I think this app has potential, seeing as how smoothly this started up. I do think that asking the user to rate almost instantly isnt necessarily a bad thing but still. as long as you keep working on it, progress is sure to come. another word of advice, you don't have to work on multiple problems in your app to make a difference. yet another word of advice, don't only think about what you want the app to be but also what others want it to be.
