# FlowFast vs Doubtful

The clearest difference is rating: Doubtful at 5.0 against FlowFast's 3.4. Doubtful also leads on ads (none vs shown) and monetization model (free vs ad-supported). FlowFast's advantage is ratings volume (5 vs 1) and iOS requirement (15.0 vs 17.6). 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.

Doubtful holds the better App Store score, 5.0 against 3.4. That said, the two scores are not equally well evidenced: FlowFast has 5 ratings behind it against 1, so its average is the more settled of the two.
