# Ameren Mobile vs FastBack Rewards

The clearest difference is rating: Ameren Mobile at 4.7 against FastBack Rewards's 3.6. Ameren Mobile also leads on ads (none vs shown) and ratings volume (13K vs 17). FastBack Rewards's advantage is review sentiment (50% vs 17%) and iOS requirement (13.0 vs 15.0). On price, in-app purchases and device support there is nothing between them.

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

Ameren Mobile holds the better App Store score, 4.7 against 3.6. That said, the two scores are not equally well evidenced: Ameren Mobile has 13K ratings behind it against 17, so its average is the more settled of the two. Written reviews complicate that: 17% of Ameren Mobile's written reviews are positive against 50% of FastBack Rewards's, so the app with the better star average is not the one people write more warmly about.

Ameren Mobile ships an update every 6 weeks, FastBack Rewards every 7 months. The most recent releases landed on October 28, 2026 and October 24, 2026 respectively.
