In one sentence, describe what the following article is about: The design should be simple enough for a new user to navigate easily. Test your app with a few friends or ideally a larger group of people who are not well versed in cell phone use. See how they perform, where they get stuck, are these intuitive, attractive and fun to use? Change your design accordingly. Similarly, people who are less educated and young users (kids) are a big market sector. The design must be intuitive enough to help them use your app without hassle. Mobile internet market is divided among different operating systems. Consider these differences before designing the app. Use responsive design to ensure that your app appears as intended throughout different platforms and operating systems. For making an app for Android your need Android Studio and for making an iOS app you can use XCode Development Kit. Use responsive design strategy to create an app that is flexible and customizable for different platforms. Responsive design refers to the idea that app or website changes its layout, fonts, and graphics according to the hosting device. Don't go for the strategy of creating a trimmed down version of your site for cell phones. Instead, first build the site for the small screen and then enlarge it for the bigger screens. The grid is an excellent tool to keep your app design consistent and on the track across multiple pages. Consistency in graphics, fonts, and icons create a professional look. Not to mention, it reflects your brand image. Not all areas have network coverage. Decide on offline usability factor of your app. Make sure that most of the features in your app work during offline sessions. In some parts of the world power outages are a regular feature of daily life, so ideally your app would be usable even if you don't have an internet connection. For making an offline experience, you need to learn serverless computing. It will be helping you in creating an offline software application.
Summary: Make new user your benchmark for design. Keep different operating systems in mind. Make sure your app works across different platforms seamlessly. Don't ignore grids. Don't forget the offline experience.

In one sentence, describe what the following article is about: Dental professionals recommend oral irrigation as a great way to really clean teeth and gums. Brushing and flossing will not get under the gums where the bacteria have set up housekeeping. Oral irrigators get what tooth brushes and floss don't, so plaque and tartar never come back. Oral irrigators flood the mouth with a jet of water under pressure to flush offending food particles and bacteria from the mouth. They can remove any debris leftover after brushing. They also give you a good gum massage, which improves blood circulation and prevents inflammation. Oral irrigators, such as Oral Breeze or WaterPik can now be found that attach to your shower-head or your bathroom sink faucet and are very easy to use. Oral irrigators should never be used as a replacement for flossing. If your diet is heavy on sweet sodas, candy, and other sources of sugar, try cutting back on these foods to decrease the buildup of plaque on your teeth. Even fruit juices have enough sugar to cause plaque to grow, and starchy foods like pizza create the same problem. When you do eat or drink sugar, follow it with a glass of water. Swish the water around in your mouth before swallowing to clean off the sugar. Consider brushing your teeth after a sugar or starch heavy meal, even if it means brushing three times a day instead of two. Carry a toothbrush in your car, office or bag so you can use it each time you feel a film start to form on your teeth. Be aware that brushing your teeth immediately after meals can potentially help to erode the natural enamel on your teeth, so make sure you only do this after eating meals that will contribute to bacteria buildup. There are some foods that have high acid contents. These acids wear away the enamel of your teeth and promote the growth of bacteria, putting you at higher risk of forming gingivitis. Some foods and drinks that are high in acid are: Citrus juices and fruits Alcohol with a high phosphorus content Certain types of meats, like corned beef or turkey Some cheeses, like parmesan, are also high in acid content
Summary:
Use oral irrigators. Avoid eating sweets. Brush after meals. Eliminate acidic foods and drinks.
