I've tried a handful of crypto apps, but most either hide fees until the last step or take forever to verify. Downloaded https://apps.apple.com/us/app/paybis-wallet-buy-bitcoin/id1584641245 out of curiosity and was surprised. Verification took maybe two minutes, first buy had zero fee, and the Bitcoin showed up in the built‑in wallet within seconds. No separate wallet, no waiting for bank transfers. Now I use it for all my small DCA buys. Simple as that.
