For holding (HODL) I’d recommend Anonero. The site is only reachable through tor (anonero.io). And technically it’s two apps. Anon (for your offline-only device) and Nero (for your everyday/online phone).
The spend keys are stored only on Anon. Nero has only view keys. If you want to do a transaction, you need to scan QR codes with the devices a few time to transfer information and the signed transaction.

For everyday use probably cake wallet.
