# Kala vs JustStretch | Flex & Mobility

The clearest difference is ads: Kala at none against JustStretch | Flex & Mobility's shown. Kala also leads on rating (5.0 vs 4.7). JustStretch | Flex & Mobility's advantage is ratings volume (2.4K vs 1) and review sentiment (64% vs 50%). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Kala sells 2 in-app purchases, starting at $0.99 per month and JustStretch | Flex & Mobility sells 17 in-app purchases, starting at $7.49 per month. Whichever you choose, the download price is not the number that matters.

Kala holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: JustStretch | Flex & Mobility has 2.4K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 50% of Kala's written reviews are positive against 64% of JustStretch | Flex & Mobility's, so the app with the better star average is not the one people write more warmly about.

Kala ships an update fortnightly, JustStretch | Flex & Mobility every 2 weeks. The most recent releases landed on September 24, 2026 and October 2, 2026 respectively.
