Looking to create shared notes

Howdy all, here’s a quick run down on what I’m looking to learn how to create. Basically, a friend and I are into fitness. We track our workouts as we go, recording how much strength we’ve gained. Being as competitive as we are, we’re always curious to know how much the other person did that day. Therefore, I’m looking to create something that has a daily calendar with the freedom of adding notes into each day. Then able to go back & take a look at previous days.

Is Fuse the place to start trying to learn how to design something like this? I’m pretty new to the ‘app creating world’. All comments are appreciated! Thanks in advance.
