# Devos vs Voltagen

The clearest difference is update cadence: Voltagen at fortnightly against Devos's every 6 months. Voltagen also leads on iOS requirement (13.0 vs 15.0). Devos's advantage is ratings volume (65 vs 4) and rating (4.7 vs 4.5). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Devos holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Devos has 65 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 94% of Devos's written reviews are positive against 100% of Voltagen's, so the app with the better star average is not the one people write more warmly about.

Devos ships an update every 6 months, Voltagen fortnightly. The most recent releases landed on August 20, 2026 and September 13, 2026 respectively.
