# Timeshifter vs JetShift

The clearest difference is ratings volume: Timeshifter at 2.7K against JetShift's 1. Timeshifter also leads on chart position (#28 vs unranked) and update cadence (weekly vs fortnightly). JetShift's advantage is rating (5.0 vs 4.7) 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. Timeshifter sells 3 in-app purchases, starting at $24.99 per year and JetShift sells 3 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

JetShift holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Timeshifter has 2.7K ratings behind it against 1, so its average is the more settled of the two.

Timeshifter ships an update weekly, JetShift fortnightly. The most recent releases landed on October 31, 2026 and October 13, 2026 respectively.
