# pliability vs Treadmill Smart Speed

The clearest difference is rating: pliability at 4.8 against Treadmill Smart Speed's 3.3. pliability also leads on update cadence (every 5 days vs every 2 months) and ratings volume (10K vs 24). Treadmill Smart Speed's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. pliability sells 2 in-app purchases, starting at $19.99 per month and Treadmill Smart Speed sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

pliability holds the better App Store score, 4.8 against 3.3. That said, the two scores are not equally well evidenced: pliability has 10K ratings behind it against 24, so its average is the more settled of the two. Written reviews complicate that: 41% of pliability's written reviews are positive against 53% of Treadmill Smart Speed's, so the app with the better star average is not the one people write more warmly about.

pliability ships an update every 5 days, Treadmill Smart Speed every 2 months. The most recent releases landed on October 20, 2026 and October 19, 2026 respectively.
