[Samsung Galaxy Gear] BarryH_GEG:
Let's face it, none from Android that are missing or those so far available on Tizen are life altering.

Here are one's I've used with some commentary.

News

It's kind of cool to stay on top of the news without pulling out your phone, especially late breaking stories.

Feedly

- It's an RSS aggregator on your phone and sends top stories to your Gear. I stopped using it on Android because CNN and News Republic were better. CNN was missing in Tizen (it's back as of today) so I started using Feedly again. The Tizen Gear apps sucks. It only gives you the headline and the lead sentence in micro-type where on Android you could see the guts of the story. Now, you can either "open on phone" or "save" to read later on your phone which, to me, defeats the purpose of having it on my Gear. With CNN's return I uninstalled Feedly.

CNN

- The Android Gear app was always wonky. Sometimes it would deliver breaking news, sometimes it wouldn't. Once you received a breaking news notification CNN stayed in notifications forever even though there was no notification which was kind of annoying. The Tizen app's great. It's cleaner, easier to navigate, and provides more info per story.

News Republic

- The best news reader for the Gear so far. It lets you choose topics (EG: top stories, breaking news, sports) from the topics you have set up on your phone. It includes pictures on the Gear and the the complete story is available by scrolling. Mobile Republic makes BlinkFeed for HTC and their mobile experience shows in the quality of their Gear app.

MarketWatch

- It was a great business oriented news app until the WSJ abandoned it on Android. It stopped updating from my phone months ago.

Lifestyle

Vivino

- What a cool friggin app. You use the Gear's camera to take a picture of a wine bottle label and it returns a rating for the wine, where it's available locally, selling price, and user reviews on your Gear. It's great somewhere like Costco where there are hundreds of wine choices; a lot of them not recognizable. You want to get people's attention stand up a bottle of wine and take a picture of it with your Gear. This came back to Tizen today and it's one I missed from Android.

TripIt

- This is the app I used most heavily on Android and the one I miss the most. It doesn't appear to be coming to Tizen at all so I'm kind of bummed. It basically allowed you to monitor your trips and track flight delays and gate changes without pulling out your phone. It was also great for just looking up something like a hotel phone number or car confirmation number. Their phone app provides real-time notifications so things like flight delays come in via notifications on the Gear but being able to proactively view and monitor your trip on your wrist was a great feature. May the app rest in peace. ;)

Glympse

- Another killer app. If you don't use Glympse on your phone it's an app that allows you to send a notification to people of where you're going, your progress in getting their, and an ETA. So if you're picking someone up or expected to arrive somewhere people can see your progress (on a map) in real time. As the sender, there's no value in seeing what you sent. So with the Gear app you could send a Glympse without ever having to look at your phone. This one's on Tizen for the 2's so it should show up for the GG1 shortly.

eBay

- I'm not a big eBay'r so this app didn't hold a lot of value for me. It was pretty flaky on Android in terms of providing real-time bidding information. It shows up in my "purchased apps" in Gear Manager but won't install so I don't know if there's a Tizen version that just might not be available for us yet. Might be a great app for heavy eBay'rs.

Social

Path

- Path was great for one reason - you could set it up on your phone to post to Facebook and Twitter and when you added something to Path via your Gear those two sites were updated also. It was also a "share" option in the Gear's Gallery App and a great way to get pics and videos off your Gear and on to the web to do something else with them (including sending links to content to non-Path users). I hope Path comes back, I miss the functionality it provided.

So in the move to Tizen I've lost three meaningful (to me) apps - Glympse, Path, and TripIt. The first is coming, the second's a maybe, and the third looks gone forever.

But, after using Tizen for about a week, I'm still glad I made the switch. Battery life is significantly better, connectivity between the Gear and my N3 greatly improved, and the on-board apps are much better when compared to their Android predecessors. I haven't seen it discussed here but Notifications in Tizen work very differently then on Android. Notifications are now just that, notifications. Samsung added a dedicated messaging app and updated logs and the e-mail app. Now, if you clear notifications, the content remains in one of those three apps until your clear them; just like it works on your phone. So you can keep the notification app clean while retaining received e-mail, MMS, and call log items. Within their respective apps you can also act (EG: reply) on one of the retained items. Pretty clean and neat.

Everyone uses their Gear differently so my commentary is based on my use. YMMV; a lot. ;)
