Banner Planes
Planes, biplanes, helicopters and the odd UFO fly your reminders across the screen, each with its own engine sound. Click a plane to mark it done for today. Holds during calls and screen lock, a water buddy reminds you to drink, and surprise fireworks keep long days fun.
Coming soon
This one is still being built. It will be $1 when it's ready.
