Try to look for theses ones 
- Wallet Of Satoshi (open source but custodial, the simplest for zaps and Lightning)
- Zeus (open source, self custodial, a little bit more for advanced users but not too hard to use, you need to "buy" your Lightning address to receive and send zaps)
- Mutiny (open source, self custodial, you need to pay a subscription to have a Lightning address but they say if you pay only one month and then stop you keep the address and they don’t care) 

 What do you mean by "zap compatible"? Every lightning wallet can "send" zaps, receiving on the other hand is much more involved.

You should also avoid fdroid: it's full of security issues and outdated software. Use Obtainium or zap.store
