Lightest 2048 I've found that works well: https://play.google.com/store/apps/details?id=com.alexblackapps.game2048
A powerful image editor (you can also paint and add shapes, etc): https://play.google.com/store/apps/details?id=com.iudesk.android.photo.editor
Several (I think 36) puzzle games in a small package: https://play.google.com/store/apps/details?id=name.boyle.chris.sgtpuzzles
One of the lightest Launchers, yet extremely powerful and customizable. Give it a try: https://play.google.com/store/apps/details?id=com.ss.launcher2
If you don't have a new Android (I think 4.2 or above), you may want to check out Settings extended. It gives you fast shortcuts on the notification area (BT, WiFi, 2g/3g, auto-rotation, etc). It grew up a little recently because now also offers a weather tile, but I can't complain: https://play.google.com/store/apps/details?id=com.hb.settings
I might add more later, but for now I have those.
I'm on Android and the one I use has sound.
