# Flutter vs Blink

The clearest difference is ads: Blink at none against Flutter's shown. Blink also leads on review sentiment (96% vs 73%) and iOS requirement (9.0 vs 15.0). Flutter's advantage is ratings volume (4.9K vs 124) and update cadence (every 8 days vs every 2 weeks). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Flutter sells 12 one-off in-app purchases and Blink sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.7 for Flutter against 4.7 for Blink. That said, the two scores are not equally well evidenced: Flutter has 4.9K ratings behind it against 124, so its average is the more settled of the two. Written reviews are what separate them: 73% of Flutter's written reviews are positive against 96% of Blink's.

Flutter ships an update every 8 days, Blink every 2 weeks. The most recent releases landed on October 28, 2026 and October 23, 2026 respectively.
