I'm iOS too but do have an android phone to test apps. I used Overcast for years before PC 2.0 but the Boosts are too cool to go back.

Fountain was super buggy when it launched a few years ago but that was all ironed out until they added Nostr and now it needs ironed out again. All part of the process and why I use multiple apps because if one is buggy I have others to use.

Love Castamatic and the only thing its missing is the Live stuff but other than that it has it all.
