The first one looks the best,...the peace signs look terrible.
And I know you're not asking for it, but just in case you value feedback; I agree that the app should be free. But lets be real, you are putting in time, and you do have to recoup SOME costs. But $3.00? No. The app does not hold $3 worth of value. The problem is the website is so basic, it functions fine on the phone. Loads quick, runs smooth. But even so, I would be willing to pay for a more refined, iphone specific app, IF it was reasonably priced. To me, $3 just seems greedy. It's not like its a lot of money, but its the principle.
Just my .02 🙂
