Verdict

The call

The clearest difference is review sentiment: 123 Flex at 100% against pliability's 41%. 123 Flex also leads on ads (none vs shown) and iOS requirement (13.0 vs 16.6). pliability's advantage is rating (4.8 vs 4.0) and ratings volume (10K vs 2). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. pliability sells 2 in-app purchases, starting at $19.99 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.

ReceptionRating · Positive reviews · Number of ratings

pliability holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: pliability has 10K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 41% of pliability'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.

UpkeepUpdate frequency

pliability ships an update every 5 days, 123 Flex every 4 days. The most recent releases landed on September 24, 2026 and June 16, 2026 respectively.
