There are a lot apps in the Android Market but not all of them are great. These are the ones I consider to be decent, helpful, or great to kill time.
APNdroid This app allows you to turn on or off your network data connection (3G, EDGE, etc.) Why is this useful? It helps conserve battery life when you don’t need to be “always connected” and it also helps limit data usage.
Task Manager by Rhythm Software You’d be surprised how many apps run in the background. Task Manager helps kill the apps, making your phone faster and improving battery life.
AndroZip This app compresses and decompresses files in the most common file types (zip, tar, rar) and also works as a file manager, it includes a task manager as well.
Dolphin Browser This browser adds sharing to delicious, facebook, and twitter fast and simple without installing other apps. It also gives you the option of downloading youtube videos when browsing youtube mobile (m.youtube.com). Tabbed browsing, gestures, and ease of use plus what I mentioned makes this my default browser for now.
Wapedia Wapedia is basically a mobile version of Wikipedia. It’s easy to search and gives you the option of opening a Wikipedia link from the browser (like search results) in Wapedia and it formats the content very nicely. It’s a handy tool.
AndFTP Great FTP app. You can add multiple servers, and it lets you upload, download, rename, delete, change permissions, etc.
Pixelpipe Pro This app is just great for uploading media to several sites. The free version is limited to text and pictures but for 99¢ it’s worth paying for the hassle free uploading to facebook and youtube on the go.
Seesmic I’ve tried a lot of twitter clients and when Seesmic added multiple accounts I installed it and never went back to the other options out there. I used Swift for a while but it wasn’t reliable outside of WiFi. Seesmic works great and has a lot of options.
Tumblroid If you really need to use tumblr on the go, this is the best app. I really recommend buying it. Developer improves the app with each update.
IcViewer This app opens pdf files. It takes a while to open them depending on the size but it works without a fuss.
Manga Droid Manga on the go! Read Japanese comics anywhere. The list of available manga is pretty long and it’s easy to pick up where you left off when you add to your favourites list.
Tube Downloader This app lets you search videos from Youtube, Daily Motion, and Google Video and gives you the option to preview, download or extract the audio in mp3 or AAC format.
FlashLight by Brenton Klik Use your phone as a flashlight, brightness can be adjusted with a touch/swipe of a finger.
Movies by Flixster Movie trailers, reviews, and local listings right on your phone. Simply awesome.
Last.fm Your personal radio station on the go. Great for discovering artists.
ActionPotato A cute game to kill time.
Iconic Memory Exercise your mind with this game. Aim for a higher score.
PapiJump Addictive little game to kill time.
Light Racer Inspired by the Light Cycle game from Tron.
Poke a Mole A whack a mole game for your phone.
My Days A period and ovulation tracker.
That’s it for my list. There always new apps coming out so I’ll be on the lookout for anything worth sharing.
