# BlueLoop vs Level One

The clearest difference is rating: Level One at 4.9 against BlueLoop's 4.0. Level One also leads on review sentiment (89% vs 65%) and ratings volume (305 vs 24). BlueLoop's advantage is update cadence (every 9 days vs monthly) and iOS requirement (13.4 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.

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

Level One holds the better App Store score, 4.9 against 4.0. That said, the two scores are not equally well evidenced: Level One has 305 ratings behind it against 24, so its average is the more settled of the two. Written reviews point the same way: 65% of BlueLoop's written reviews are positive against 89% of Level One's.

BlueLoop ships an update every 9 days, Level One monthly. The most recent releases landed on October 23, 2026 and October 28, 2026 respectively.
