Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Z5 Mobile holds the better App Store score, 3.7 against 3.0. That said, the two scores are not equally well evidenced: Z5 Mobile has 127 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 36% of Z5 Mobile's written reviews are positive against 50% of Elioz's, so the app with the better star average is not the one people write more warmly about.
Z5 Mobile ships an update every 2 months, Elioz every 6 months. The most recent releases landed on September 30, 2026 and September 14, 2026 respectively.
