123 collection Productivity iPhone & iPod Touch App Review & Download

in many ways we collect numbers and not things, this is a collection database manager that specialises in just that, a list with colour-coded numbers.
Mark the numbers with a color-code like you would typically do on a paper list. Simple, very fast and effective.

There is a email feature but no real import or export, so it is advised to use "123-collection" only for casual information and not for very large collections.

Features:
- email a complete category
- color-code 5 numbers with a swipe from left to right
- delete numbers
- rename colors
- long category names
- add personal info for each category
- database is 4 category's deep
