Nice, effective app, but interface needs improvement.


This app strength is in allowing you to find a contact with a few thumb-clicks and a few glances at the screen, which is great in situations when only one hand is available to hold your iphone, and not much eye-time to glance and scroll through your contacts.
The weakness are its interface: red-on-white is not the most friendly color to glance at. Why not black-on-white, or let the user choose the colors via a prefs? Also the letters are too small: most of the time the app is displaying 4 letters, so make them visible (bold at least).
This app would be great if it could speak the 4 choices, in clockwise order, say. Then one could find a contact w/o looking at the screen at all. Now that would be useful and innovative.

Marginally better than built-in Contacts


Very ingenious name for this application.

I find that my thumb can easily reach any function in the iPod Touch's Contacts. That combined with the fact that this application is not very speedy does not add any value. As a matter of fact, I could find contacts faster in Contacts more than half of the time than using Thumbtacts. Surprisingly, with many contacts, it took less "thumb-clicks" with Apple Contacts than it did in Thumbtacts!

But, this app is free, so try it out and see if it works for you.

Finally an easy way to access my contacts

Excellent app. Only suggestion would be to allow for priorities

Update on the new release: definitely much faster and thanks for addressing the priority request. This is my favourite app.
