# ShiftPower vs Cartomizer

The clearest difference is in-app purchases: ShiftPower at none against Cartomizer's 1. ShiftPower also leads on update cadence (every 2 weeks vs every 3 months) and rating (4.8 vs 4.6). Cartomizer's advantage is ads (none vs shown) and review sentiment (86% vs 61%). On price, ratings volume and iOS requirement there is nothing between them.

Both are free to download. Cartomizer sells 1 one-off in-app purchase. ShiftPower asks for nothing beyond the download.

ShiftPower holds the better App Store score, 4.8 against 4.6. Both are backed by a comparable volume of ratings — 356 and 522 respectively. Written reviews complicate that: 61% of ShiftPower's written reviews are positive against 86% of Cartomizer's, so the app with the better star average is not the one people write more warmly about.

ShiftPower ships an update every 2 weeks, Cartomizer every 3 months. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
