# Bookli vs eTuning

The clearest difference is update cadence: eTuning at every 2 weeks against Bookli's every 5 months. eTuning also leads on ratings volume (6 vs 1) and iOS requirement (13.0 vs 15.0). Bookli's advantage is review sentiment (50% vs 36%). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Bookli holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: eTuning has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 50% of Bookli's written reviews are positive against 36% of eTuning's.

Bookli ships an update every 5 months, eTuning every 2 weeks. Both last shipped on November 7, 2026.
