TLDR and FAQ
Do I need to pay for In-App purchase to zap?
NO!
In App purchase is an optional feature that you do not need to use.
Check out the App yourself and let us know.

are my keys safe?
Great question. YES. The keys are only stored on your phone and never leaves the phone. The key storage on the phone is encrypted and only used when you trigger an action on the App. It also uses all Apple encryption features on the App and phone.
Looks great!
Checking it out via the TestFlight version. Couple of issues on iPhone 13
1. I can’t zap. I reloaded my wallet, but when I try to set a default zap amount I can’t close the keyboard (so I can’t save the default amount)
2. Before I enabled the premium features, I tried to enable the push notifications. I saw the warning about needing premium, then the app froze up
Thanks for reporting. Will go into our issues list. Push notifications is not linked to the subscription option yet.
