Found this app to track my progress

I found a pretty cool app on the Play Store to track my progress. Just thought I would share it just in case anyone wants to try it. It’s called “Track my Progress”. I’m not sure if it’s for iPhone or not. What apps do you guys use to help with your endmyopia journey?

Also… Is that normal for my eyes to improve that quickly in the first month? Or maybe I am just being inconsistent on what I consider “edge of blur” which could throw off the cm measurments
