# Keep vs SwimLog

Keep and SwimLog both sit at 4.8 stars, but that hides the real split: 100% of SwimLog's written reviews are positive against 52% of Keep's. SwimLog also leads on ads (none vs shown) and update cadence (every 3 days vs weekly). Keep's advantage is ratings volume (17K vs 2) and device support (4 vs 2). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Keep sells 5 in-app purchases, starting at $2.99 per month and SwimLog sells 2 in-app purchases, starting at $14.99 per year. Whichever you choose, the download price is not the number that matters.

SwimLog holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Keep has 17K ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 52% of Keep's written reviews are positive against 100% of SwimLog's.

Keep ships an update weekly, SwimLog every 3 days. The most recent releases landed on November 10, 2026 and November 5, 2026 respectively.
