# 123 Flex vs Stretchlet

The clearest difference is review sentiment: 123 Flex at 100% against Stretchlet's 50%. 123 Flex also leads on update cadence (every 4 days vs every 9 days) and iOS requirement (13.0 vs 16.4). Stretchlet's advantage is rating (4.7 vs 4.0) and ratings volume (30 vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. 123 Flex sells 2 in-app purchases, starting at $9.99 per month and Stretchlet sells 6 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Stretchlet holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: Stretchlet has 30 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 100% of 123 Flex's written reviews are positive against 50% of Stretchlet's, so the app with the better star average is not the one people write more warmly about.

123 Flex ships an update every 4 days, Stretchlet every 9 days. The most recent releases landed on October 24, 2026 and October 21, 2026 respectively.
