Let me start, I suppose. Although, at the moment, I really don't use many (except the AOSP ones) at all
gStrings Free Tuner
- I play the bass and having a phone as a decent tuner comes in rather handy at many occasions and I've found this app to be pretty accurate, as well. The author has since made a fancier version called "Waves" but I've remained faithful to this one.
CM Next Camera - this has been my favourite camera app ever since I first installed it while I was on CM11 with my R HD. The UI is simplistic, yet absolutely perfectly intuitive for me - you set all your modes up and just flick through them with up and down swipes, while video recording starts as soon as you hit the dedicated in-app button. No need to switch to video camera mode first, as in many other apps, and no need to go into any menus if you, say, want to capture that beautiful scenery before you in HDR mode. But, ever since CM12 came along, it just doesn't seem to work as well, at least not for me. It often does a shot off-focus and the exposure and colour balance just aren't as good as they should be. I've searched and found newer versions of the apk, but it didn't help. I'm looking for an alternative now... Might switch to Camera Zoom FX, because that has given me great shots whenever I used it, but I'm open for other suggestions! I don't expect an DSLR-like pictures, don't get me wrong, but there's clearly something amiss here.
- I've tried all of the fancy e-mail clients, but I always come back to K-9. It's just feels the most robust of all and it does everything I need. I don't mind if I need to tap the screen once or twice more than I would with a different e-mail client.
QuickOffice Pro - version 5.5.209 - this is an app I got from my old Defy and just continued installing it on the R HD. I've tried switching to different, newer versions and apps and I just don't find them as good. This works very fast, isn't bloated with a fancy UI, and has been able to open everything else any other office app can as of now. Is there a worthy replacement?
