Verdict

The call

The clearest difference is ratings volume: FeelFlow at 12K against SunAlly's 9. FeelFlow also leads on rating (4.7 vs 4.3) and device support (4 vs 2). SunAlly's advantage is update cadence (weekly vs fortnightly) and review sentiment (60% vs 50%). On price, ads, in-app purchases and monetization model there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. FeelFlow sells 5 in-app purchases, starting at $9.99 per year and SunAlly sells 3 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

FeelFlow holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: FeelFlow has 12K ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 50% of FeelFlow's written reviews are positive against 60% of SunAlly's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

FeelFlow ships an update fortnightly, SunAlly weekly. The most recent releases landed on October 16, 2026 and September 17, 2026 respectively.
