As the developer of Puff Counter AI, I hit my first $1K in revenue within a month. But this is just the beginning—I’ve been refining the product using AI, behavioral science, and data-driven monetization strategies. Here’s what worked for me and how I’m scaling further:

How I Reached $1K in a Month with My Puff Counter AI App

1. Solving a Real Problem with AI & Behavioral Science
Most vaping trackers simply log usage, but they don’t help users change behavior.

I designed AI-powered reduction plans based on BJ Fogg’s behavior model, ensuring users reduce puffs gradually and sustainably.

The app personalizes recommendations using prompt engineering, analyzing the user’s patterns to provide tailored reduction strategies.

Instead of generic tips, every user gets a dynamic AI-generated plan based on their onboarding data.

Use Apple Shortcuts and Siri to add new puff, Even app is close you can add puff just click back off device (People love that easy life trick use them !)

2. Leveraging Subscription Model & A/B Testing with RevenueCat
Instead of a one-time purchase, I launched a freemium model with RevenueCat v2 paywalls.

The free tier provides core tracking, while premium unlocks AI-powered insights, personalized reduction plans, and savings calculations.

A/B testing with RevenueCat helped me fine-tune the best-performing paywall design. Early results? A 20% increase in trial-to-paid conversions.

And you can see, I have many A/B Test not one!

3. Optimizing ASO & Targeted Growth Strategies
Keyword Strategy: Focused on not really high search terms like “quit vaping,” “puff tracker,”

Tiktok & Twitter Marketing: Targeted content around real user progress stories brought in engaged users at a low CAC.

4. Reimagining Onboarding for Long-Term Engagement
Instead of rushing users into the app, I designed a longer, in-depth onboarding process that captures their habits, motivations, and reduction goals.

This is where AI meets behavioral science:

Users input their smoking habits →

The AI constructs a personalized behavior-change plan →

Dynamic messaging adjusts based on user progress

The result? Users stay longer and actually engage with the reduction plans.

5. Automating Analytics & Scaling for Growth
Firebase & serverless functions handle tracking, engagement analysis, and personalized recommendations.

Stripe API + RevenueCat seamlessly manages subscriptions.

Automated feedback collection helps continuously refine features based on real user insights.

I use for mixpanel for eventing. Events are reaaly matters ! COLLECT EVENTS !

What’s Next?
Now that I have a solid monetization foundation, my next steps include:
Expanding A/B testing on pricing models and paywall variations
Enhancing AI-driven coaching based on more advanced habit-forming techniques
Experimenting with longer-term engagement strategies (gamification, deeper analytics)

If you are here please I really need your feedbacks. Thanks :)

NEXT GOAL IS $2K

This is just the beginning—if you’re an indie dev, my biggest advice is: Solve a niche problem, experiment fast, and leverage data to optimize!
> Are AI build games a real thing?

No.

Making the game with AI isn't the point.

What you've just described is a power law distribution.

One person who has a huge audience and has a lot of distribution has the most attention, the others who want to ride the wave/latest fad have a smaller reach will most likely make 0-$100 annually copying Levels with this game and nowhere near or more than $38K currently made by Levels.

Why not make the 50,000th Wordle clone with AI and try to make $1M+ with it?
It is a OS.
Intended to run on mainstream devices.

Main difference to Linux: stable driver API. So vendors could make their blobs and support them easier, without open sourcing, like linux demands.
it is still supported and developed.
It depends on the exact meaning of "YCbCr" and the meaning of "RGB". Is it BT.601? BT.709? BT.2020? Adobe RGB? Display P3?

Also extra fun is guaranteed if one end of the video cable is encoding with e.g. BT.601 primaries, while the other end is decoding as e.g. BT.709, or vice versa.
There’s no “propaganda network.” America has a president that overthrew the GOP leadership by destroying Jeb Bush over the Iraq War: https://youtu.be/H4ThZcq1oJQ?si=ZawKMFFY3LmAhYMr. After the mistakes of the last two decades, there is little appetite in America to do anything in foreign countries americans can’t find on a map beyond empty virtue signaling.
I'd watched the whole thing live when it happened. I went back and watched from around 21min in to see what self-immolation you mean.

Sequence of events -

Trump downplays the need for security guarantees. "Security is maybe 2% of the problem, security is the easy part, I'm worried about getting the deal done."

A "reporter" from OAN asks a kiss-ass question that can be summarized as "President Trump, how amazing and courageous are you for negotiating with Putin?"

Trump gives a rambling answer including his usual vague statements of how the war wouldn't have existed if he'd been in power and then starts talking about Hamas for some reason.

There's a moment of levity where Trump says Zelensky's attire is fine.

Zelensky indicates he wants to respond to some of the earlier statements. He says Russia has broken many promises made in past negotiations and this is why security guarantees are actually critical to Ukraine.

"Reading the room" in this situation would mean "buying into the Putin-led narrative currently being peddled by the Trump administration."

Fuck that.
I've read that in war gaming a Chinese invasion of Taiwan the US can stop it BUT they usually lost TWO aircraft carriers. That would be almost 14,000 dead US soldiers.
When those people get richer they'll want to drive. We see this all over the developing world. The growth might be less than the growth in mass transit but as populations become richer they become more mobile so the absolute demand will likely increase.
A blockade takes time to have an effect and that time gives US Navy SSNs time to start sinking the PLAN (in righteous response to the PLAN attacking merchant ships approaching Taiwan.)

For the PRCs invasion of Taiwan to work with minimal risk of excessive losses, they need to do it very quickly so that it's a fait accompli, minimizing the chance of any American response at all.
Man every time I read someone complaining about the new photos app it feels like they never even tried looking for a solution. "It changed, so it's broken."

I hope they reconsider. The US does not appear to be a counterparty which can be trusted to follow through with their obligations anymore and this venture sounds quite risky.

I found a cheap plastic Faber-Castell sharpener in the drawer yesterday. No idea where it came from, but it was razor sharp and the perfect angle for my double-ended Mitsubishi 772 red/blue. I’ll definitely be ordering more of those, and will check out their other offerings too.
It's the only explanation that makes any sense.

But it wouldn't be a financial debt more likely some humiliating kompromat. That's Trump's biggest fear.

And Putin probably has plenty from Trump's visits there.
How would that help? Someone still has to write drivers for devices.
One of the reasons for the collapse of the USSR was that the propaganda done by the US was better than the propaganda done by the Soviets. So it's not like there isn't a historical reason for this either.
This seems like one of Putin's motivations for invading Ukraine. He couldn't stand having a prosperous Ukraine aligned with the EU and the US that could foment discontent inside Russia.
People are using Super Mario to benchmark AI now
I disagree. I believe it's the load-bearing analogy that's carrying all the ideas in the article. Consider e.g. the sections "The benefits of small docs" and "Avoid blocking yourself during reviews" - they're mostly about workflow. They apply to changesets, not the artifact itself.

I feel like there's an implied assumption in the article, that documents are always submitted and reviewed wholesale, so to get the benefits of small commits, you need to make the document small enough to qualify as a small commit. If that's the idea, then I disagree with it.
I guess the market regulated itself. /s

The quality crisis is systemic throughout the whole economy. So many fields are getting more disorganised, messy and chaotic.

On the one hand things are moving faster, doing more with less, being more responsive etc. But this comes at the expense of quality and long-term reliability / support. Applies to hardware too.
Yes. And it works (well enough) because at speed the chunk of air it forces up mixes with the air above the bike (that the rider would otherwise hit with their face) and disturbs it so the rider experiences something more a akin to riding in a pickup bed than to sticking their head out a sunroof.

How are Taiwan and Hong Kong at all comparable? Hong Kong never had their own military, was never an independent nation, and was officially handed over from Britain to China in 1997. There was no armed invasion of Hong Kong - Chinese military was already garrisoned there for 25 years.
The question is about systems programming.
Which is a valid but entirely different complaint from claiming those reports are being sent every 15 minutes. What sense would that even make? They could just log your data anyway without you knowing or providing a setting for it. Why would they make it a toggle for something you need to provide authentication to access?
Those are massive SUV-type things with apparently rather weak engines (ie almost light hybrids, but with a plug); the typical plugin hybrid is a fair bit smaller. And has a bigger battery; the Mitsubishi Outlander mentioned had a 12kWh battery, vs, say, a plug-in Prius, a much smaller car with a 14kWh battery,

Many plugin hybrids only need to use their petrol engine when they actually run out of power. I would wonder if whoever came up with the above study was deliberately looking for a worst case scenario, tbh; they didn't include any small/normal-sized cars at all (everything they mention is over two tonnes), even though the _average_/most typical plugin hybrid car is probably some sort of smallish hatchback.

(Even then, though, I'm curious what conditions they're testing under. I know someone who has a BMW 5-series plugin hybrid saloon, which is a close relative of the X5 mentioned, albeit a bit lighter and more aerodynamic, and it operates pretty much entirely on battery when charged.)
Even if the PRC can't be sure America would respond, a small risk of America responding has some deterrent effect. Hopefully enough.

> We need to get behind Mozilla and Firefox

That's some bizarre upside-down-world Stockholm Syndrome thinking on display here. That or you are a paid PR influencer working on behalf of Mozilla. Just absolutely astonishingly weird psychological behavior.

Mozilla is violating user privacy. They are the bad guy. You don't ask the bad guy for help. You punch them in the face. These guys are making it worse, not better, and helping them will only make privacy worse, not better.

There are already multiple forks for Firefox and destroying Mozilla as an organization would greatly help one or more of them take off and carry the banner of true enabling privacy for the user, which Mozilla is not doing.

> "it's not meant to replace JavaScript"

The word meant is doing a lot of heavy lifting here. Meant - by who? The technology itself doesn’t want anything.

Do some people want to use wasm instead of JavaScript for websites? Yes. Will JS ever be removed from web browsers? Probably not, no. Wasm isn’t a grand design with a destiny it’s “meant to” reach. It’s actually just some code written by a bunch of people trying to solve a bunch of disparate problems. How well wasm solves any particular problem depends on the desires and skills of the people in the room, pushing the technology forward.

It’s kind of like that for everything. Rust was never meant to be a high performance systems language by its original creator. But the people in the room pushed it in that direction. Fuscia could replace Linux in Android. I’m sure some people want that to happen, and some people don’t. There’s no manifest destiny. What actually happens depends on a lot of arguing in meeting rooms somewhere. How that turns out is anyone’s guess!
Simple Explanation of LLMs
Hello, tried to explain Large Language Models with some visualizations, especially the attention mechanism.
I don't think that's accurate. The population is concentrated on the west coast, all that mountainous terrain is unpopulated. Also it's an island that's very close to China.
During the cuban missile crisis back in 1960ish, R̶u̶s̶s̶i̶a̶n̶ Soviets actually had reached the point where they had launch-ready, on-ramp nuclear missiles.
We learned some 20 years later that the US had deployed nuclear missiles of their own in Turkey, and the agreement was to remove those missiles in return.
Back in those days, we had no "nuclear suitcase" for approving a nuclear launch,
and we had US warships surrounding Cuba ("quarantine", brilliant Pres. Kennedy!), themselves encircled by Soviet nuclear-equipped submarines.
I'm glad these men knew what is war like, and didn't get humanity dragged into a MAD, like all of these civilians today are trying to do.
Let's just do a cease-fire, whatever the reason, let's just stop firing, and let's talk.
The enemy is the enemy, this is what it is, but let's not forget, quoting Hemingway, that they are the enemy just because we were born on this side of the mountain, and them on the other side.

Why is this stuff not reported in the mainstream media?

The general publics opinion of Apple is that they are golden and untouchable, the best tech company out there. The reality is much different.
This fine. But from the fact that prices are sometimes high, we can conclude that overlll there is a shortage of windpower. Which will factor into the prices. The owner of the windpark can take the prices for each hour, and compute weighted average with production. And set that as the constant price.

So the consumer does not gain anything.

As the sibling comment says: Ability to resell EVs is a problem. But that's mostly because you can get a new car today (i.e. deliverable and everything) for the same price as an older EV and likely the new car is even better (larger battery, faster charging). That's unfortunate for first adopters and is a significant problem for adaption in lower-income circles (those typically buying second hand), but not a reason for going back to gasoline cars.

At least here in Germany we are rapidly approaching the point where we will require power sinks in order to absorb solar around noon. And EVs are extremely well-positioned for that. Typically the charging time can be shifted around a bit and charging stations will come with their own buffer stage. That means that most people won't pay anywhere near the normal sticker price for electricity for their cars.

All that being said: I agree that "green agenda items" will decrease in popularity (or really: they weren't that popular to begin with). But EVs in particular are just straight up cheaper. If not by construction, then definitely by the air pollution reduction interest of the Chinese government. I'd be highly surprised if incentive reduction has more than a delaying effect, if even that
>Invading a neighboring nation doesn't seem too appealing if it means sending tens/hundreds of thousands of your young people (a resource that's getting scarcer and scarcer most everywhere in the world) to the meat grinder. Millions of drones though...

Sorry but this is alarmist bullshit. What keeps countries from going to war is not the cost in soldiers; it's the cost of retaliation on its home soil. Indeed, countries that don't anticipate the enemy to meaningfully retaliate on its civilians are quite trigger-happy to engage in various small wars around the world.
> I think the problem you describe can be solved by having more contributors focussing on the standard library.

I don't think so, my impression is that stdlib improvements are volontarily frozen for now, not because of a lack of contributors but because of a lack of clear plan as to what the stdlib should look like. There are a number of issues and PR of people willing to contribute to stdlib that are stalled.

That's not to say that's its bad per se, "we don't have a plan for now and don't want people to commit time for an unclear target" is a perfectly OK answer.

> when Russia attacks the Baltics in a few years

I wonder what media do you consume to get this absolutely ridiculous idea? baltic states have no beef with Russia (except petty provocations which Russia seem to dismiss), Putin never ever said he will do anything like that and actively emphasised he won't. Where the idea of Russia attacking Baltic states or any other european nation to that matter, have stemmed from (besides nonsensical statements of unelected EU bureaucrats like ursula, who have vested interest in stealing money through warmongering)?
Rental bikes use heavy, incompatible components so it’s pointless to steal them for resale, or to strip for parts. And they have a tracker.

> Corruption bugs are exceptionally rare in SQLite these days.

I develop a third party software and I receive reports of corrupted SQLite databases roughly every 2 months.

However, without any reproducibility, it might very well be due to hardware faults etc.

Trump cited Russian propaganda of Zelensky‘s 4% approval rate.

So where did he get that from?
The most frustrating thing with PowerToys is trying to remap keys (like caps lock to Ctrl). It feels like it's done by intercepting the keypress at runtime in the app rather than being configured at the system level, so if you happen to, say, hit your new Ctrl key when the CPU is pegged, it'll revert back to caps lock and then also get stuck. So you have to go into PowerToys to unbind the key, turn off caps lock, then rebind it.

There's another app that does this in the registry I think, but I keep forgetting the name of it.

DVDs whilst not a great medium for archival storage, are essential for archival purposes, so many films, TV shows, or just removed scenes or alternate cuts of each are on DVD only.

>Exceptional circumstances, or exceptions for short, mean "things aren't working as expected due to programmer error".

Interesting. In Javaland this describes assertions, and the term exception is for operating errors, i.e. problems not necessarily attributable to programmer error, including your example of a network failure.
