I bought a Galaxy 3 over a month back. It is a really good phone for its price and fun to use too. I have quite a few apps installed and found some really nice ones.
The phone comes with a pre-installed copy of ThinkFree Office, which is fine for editing and viewing office documents. It also lets you view PDF files.
The Daily Briefing app is useful, showing your calendar tasks and weather updates, apart from Yahoo Finance and AP News (both of which I don’t use).
I use Daily Expense Manager to keep a tab on my spendings, it’s a really useful app apart from the fact that you can only enter expenses, not income.
The Evernote and Dropbox apps are pretty usable and are actually useful, even on the slightly cramped screen.
Internet and Social:
Opera Mini is the browser of my choice, for I can get Indic fonts to work with it. Dolphin Browser is good for viewing full websites (not mobile-optimized) if you are on 3G, but Opera Mini is far more useful for those stuck with GPRS and EDGE.
There are apps for Twitter, Facebook, etc but I prefer to use TweetDeck.
The GMail app is good, and there is an app for Yahoo! Mail too. But the default mail client doesn’t work with my work mail which uses Exchange.
There is a Google Talk client, but I prefer Meebo as it lets me connect to multiple IM services.
I have the WordPress app installed, which I am using to publish this post. The Youtube app is the only place where Flash works, and the app is good enough to view a short video. The small screen doesn’t actually let you enjoy longer videos, such as movies.
Games and Entertainment:
I am not much of a gamer, but I tend to play a few games when I feel like it. I particularly love Slice It, which is a lovely game that tests your touchscreen skills and also a bit of geometry.
I have quite a few Sudoku games installed, however I’ll be uninstalling almost all of them soon. This is a situation where I might as well create an apk for my own use.
Jewels is similar to Gweled ( a.k.a Bejeweled) and I like it enough to let it stay on my phone.
I use FBReader to read books. I tried out Aldiko and a few other apps, but not fit the bill apart from FBReader.
The Google Scoreboard app is fine, but seriously seeing cricket scores like Australia 245 – 620 England is not what I wanted, so I use ESPN ScoreCenter.
The default media player works fine, but it doesn’t remember the last played song, so I use Winamp. It lacks an equaliser, but it is a decent audio player with a touch of nostalgia.
Lookout is a security app that scans applications when you install them. You can also back up your contacts online using a free account. AppBrain is useful for installing apps, and is a good replacement for the default Market app. AppMonster lets you manage your installed apps effectively and also back up the APKs to SD card. APNDroid lets you switch off and on data services easily. Google Reader, Sky Map and Maps work well too. NetCounter lets you keep track of data usage for different networks (EDGE, Wi-fi). NeoReader is the best barcode reader app I’ve seen for this phone. RealCalc is an advanced calculator and I love it.
If you have any apps that you love, do share it in the comments. Cheers!
