Verdict
The clearest difference is rating: Start Stretching at 4.6 against 123 Flex's 4.0. Start Stretching also leads on ratings volume (3.6K vs 2). 123 Flex's advantage is ads (none vs shown) and update cadence (every 4 days vs every 4 months). On price, in-app purchases, monetization model and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Start Stretching sells 1 one-off in-app purchase 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.
Start Stretching holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: Start Stretching has 3.6K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 80% of Start Stretching'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.
Start Stretching ships an update every 4 months, 123 Flex every 4 days. The most recent releases landed on November 11, 2026 and November 3, 2026 respectively.
