I just wrote a three star review saying that I was not able to get the highest key to align. After I submitted this review, I went back into the app and tried again and succeeded! My only issue now is that the dots are not centered on the keys correctly, which makes it difficult to play chords while looking at the screen, because I’m not sure what notes I should play. I tried realigning by standing at the center of the keyboard and pointing the camera at the highest and lowest keys, but that did not seem to help much either. As I said before, this app has a lot of potential. It just needs to have some minor bugs fixed. I just wrote a three star review saying that I was not able to get the…from apps.apple.com

  • Retoolâ–²640

    Hi all, founder @ Retool here. We initially launched Retool on HN five years ago: https://news.ycombinator.com/item?id=14515494. The feedback was extraordinarily helpful then (e.g. we launched source control, on-prem, etc. based on HN comments), and we’re grateful for all of it.

The idea is there is a large class of line-of-business mobile apps, and the process of getting a simple form + button on a mobile device, in a native app,…
