# Charging Engine vs Sticker Maker

Charging Engine and Sticker Maker both sit at 4.8 stars, but that hides the real split: 94% of Sticker Maker's written reviews are positive against 52% of Charging Engine's. Sticker Maker also leads on monetization model (freemium vs subscription). Charging Engine's advantage is ads (none vs shown) and ratings volume (11K vs 2.1K). On price, rating, update cadence and in-app purchases there is nothing between them.

Both are free to download. Charging Engine sells 12 in-app purchases, starting at $3.99 per 7 days and Sticker Maker sells 4 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.8 for Charging Engine against 4.7 for Sticker Maker. That said, the two scores are not equally well evidenced: Charging Engine has 11K ratings behind it against 2.1K, so its average is the more settled of the two. Written reviews are what separate them: 52% of Charging Engine's written reviews are positive against 94% of Sticker Maker's.

Charging Engine ships an update every 6 weeks, Sticker Maker every 3 weeks. The most recent releases landed on October 28, 2026 and October 27, 2026 respectively.
