# Stretching Mobility vs 123 Flex

The clearest difference is rating: Stretching Mobility at 4.8 against 123 Flex's 4.0. Stretching Mobility also leads on ratings volume (15K vs 2). 123 Flex's advantage is review sentiment (100% vs 61%) and update cadence (every 4 days vs every 8 days). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Stretching Mobility sells 11 in-app purchases, starting at $4.99 per month and 123 Flex sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Stretching Mobility holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: Stretching Mobility has 15K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 61% of Stretching Mobility's written reviews are positive against 100% of 123 Flex's, so the app with the better star average is not the one people write more warmly about.

Stretching Mobility ships an update every 8 days, 123 Flex every 4 days. The most recent releases landed on September 24, 2026 and June 16, 2026 respectively.
