# Expert vs ShiftPower

The clearest difference is rating: ShiftPower at 4.8 against Expert's 2.7. ShiftPower also leads on review sentiment (61% vs 25%) and ratings volume (348 vs 15). Expert's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, in-app purchases and device support there is nothing between them.

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

ShiftPower holds the better App Store score, 4.8 against 2.7. That said, the two scores are not equally well evidenced: ShiftPower has 348 ratings behind it against 15, so its average is the more settled of the two. Written reviews point the same way: 25% of Expert's written reviews are positive against 61% of ShiftPower's.

Expert ships an update monthly, ShiftPower every 2 weeks. The most recent releases landed on October 3, 2026 and October 11, 2026 respectively.
