There is an Android and web app for CLN nodes. It's called Spark Wallet.

I saw it actually. But so far it seems like it doesn't use sats, but "bits". Are they the same?
You can change it to sats:
> Display unit: Click the balance on the top-right or the unit in the "request payment" page to toggle the currency display unit. The available options are sat, bits, milli, btc and usd.
