In this thread - https://cake.co/c/yzgJBVC/fF51zw8 - there is a comment from @Chris about why the iOS app was developed first.
I added a shortcut to Cake on my Android phone and I find it works quite well. I didn't know that was possible until someone here pointed it out. With the site open in Chrome on your phone, click the 3 dots in the upper right, then "Add to Home Screen".
I plan to try the Android app when it is available but for now the shortcut is very usable.
