Verdict
The clearest difference is monetization model: Flow Free at free with in-app purchases against Fill ·'s subscription. Flow Free also leads on review sentiment (84% vs 63%) and ratings volume (10K vs 1.6K). Fill ·'s advantage is ads (none vs shown) and update cadence (monthly vs every 5 months). On price, rating, in-app purchases and device support there is nothing between them.

Both are free to download. Flow Free sells 11 one-off in-app purchases and Fill · sells 4 in-app purchases, starting at $7.99 per 7 days. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.8 for Flow Free against 4.7 for Fill ·. That said, the two scores are not equally well evidenced: Flow Free has 10K ratings behind it against 1.6K, so its average is the more settled of the two. Written reviews are what separate them: 84% of Flow Free's written reviews are positive against 63% of Fill ·'s.
Flow Free ships an update every 5 months, Fill · monthly. The most recent releases landed on October 21, 2026 and October 20, 2026 respectively.
