iOS APP:Coffee It - Track Caffeine in Simplest Way

PNG 图像-7186AF5662CA-1


Coffee It is an iOS APP that builds for those who drink Coffee a lot. There are a group of people who want to log all Caffeine they drink each time. And from all iOS APPs, most Caffeine Tracker APP are abandoned in a few time, without further bug fixes and improvement, the APP is difficult to use. The rest are expensive, and less functional. This is why I develop Coffee It.

Please download Coffee It - Track Caffeine in Simplest Way and give a try!

For me, it only takes a seconds to log the coffee before I throw the empty cup, so if you feel it’s not that good to use, give me feedback and I will try my best.

Using telegram to give me feedback: @o1xhack

As a student with spare time for these APPs:

Leave a 5-star if you like it or want support me!


I’m a student in Computer Science, and I learn Swift and iOS Development myself.

This APP may not fulfill every coffee lover’s requirement, but I will keep developing it with any feedback! I cannot assure I can do every function since I still need time for my University Study, but with my spare time, I will do my best in improving it.

As you can see, I’m consistently making Coffee It faster and easy to using, for me, it only takes a seconds to log the coffee before I throw the empty cup, so if you feel it’s not that good to use, give me feedback and I will try my best.


I put all my time on my developing process (beside student works) that I don’t have time to write a whole article for features, here are the summary.

I sincerely appreciate you give me any advice or leave a 5-star with comment!
