# StopJetLag vs Timeshifter

The clearest difference is review sentiment: Timeshifter at 92% against StopJetLag's 8%. Timeshifter also leads on rating (4.7 vs 2.3) and update cadence (weekly vs every 2 months). StopJetLag's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. StopJetLag sells 1 one-off in-app purchase and Timeshifter sells 3 in-app purchases, starting at $24.99 per year. Whichever you choose, the download price is not the number that matters.

Timeshifter holds the better App Store score, 4.7 against 2.3. That said, the two scores are not equally well evidenced: Timeshifter has 2.7K ratings behind it against 12, so its average is the more settled of the two. Written reviews point the same way: 8% of StopJetLag's written reviews are positive against 92% of Timeshifter's.

StopJetLag ships an update every 2 months, Timeshifter weekly. The most recent releases landed on October 15, 2026 and October 20, 2026 respectively.
