smrtPhone holds the better App Store score, 4.6 against 3.3.

Written reviews complicate that: 41% of Zadarma's written reviews are positive against 25% of smrtPhone's, so the app with the better star average is not the one people write more warmly about.

Zadarma ships an update every 2 months, smrtPhone fortnightly. The most recent releases landed on September 24, 2026 and September 22, 2026 respectively.
