Ink Cartridge Compare app for iPhone and iPad

I was standing in a store trying to figure out which ink cartridge was the best one for me to buy. The one in this store? The one in the previous store Id been into... Or the one on eBay??

I tried to do it in my head and managed to get it wrong. The problem was that each cartridge printed a different number of pages and I couldnt figure out which was the best value.

So, I developed Ink Cartridge Compare so that I can figure it out easily each time I shop.

Ink Cartridge Compare allows you to:
- Enter the name, price and expected number of pages printed of two ink cartridges.
- Adjust the cost of them for a fixed number of pages of your choice.
- See which one is best value.

Ink Cartridge Compare:
- Keeps your data saved so its there the next time you launch the app.
- Allows you to reset all data.
