About Android Apps of the Day

Android has over 450,000 apps. With so many apps out there, app discovery (aka finding new and useful apps) is extremely difficult. With our Android Apps of the Day initiative, dotTech aims to change that. Everyday we post three apps, allowing our readers to discover new apps, daily. Enjoy!

Apps for April 29, 2012


Aside from price, one of the most important factors when selecting a cell phone service provider is coverage: Will you get reception at your home and other places you visit? Sensorly is an app that aims to answer that latter question. Using data garnered from its users (“millions of recording [data readings]” according to the developer), Sensorly provides information on the cell phone reception of every cell phone company that serves your area. Sensorly tells if your area is covered by 2G, 3G, or 4G and tells you the strength of the signals; information on network speed is planned in the future. Depending on where you live, you will also be able to view cell phone coverage on maps. If you want to see cell phone coverage in an area other than your own (maybe you will travel soon and want to know which local company to go with), you can do that, too — Sensorly provides information on all/most carriers in the world.

CSS Reference

Need a reference for CSS? is an excellent website for that. Want w3schools CSS information on your Android device? CSS Reference is the app for that. CSS Reference is an app that takes all CSS information from w3schools and puts it on your Android device; it is even available offline, so no Internet access is required (although one may question why you need a CSS reference guide if you don’t have Internet access since CSS is coding for websites).
