# Levelgas vs DuoSmart

The clearest difference is rating: DuoSmart at 4.2 against Levelgas's 2.0. DuoSmart also leads on in-app purchases (none vs 2) and ratings volume (19 vs 4). Levelgas's advantage is update cadence (every 3 weeks vs every 9 months) and review sentiment (40% vs 25%). On price, ads, monetization model and device support there is nothing between them.

Both are free to download. Levelgas sells 2 in-app purchases, starting at $1.99 per month. DuoSmart asks for nothing beyond the download.

DuoSmart holds the better App Store score, 4.2 against 2.0. Both are backed by a comparable volume of ratings — 4 and 19 respectively. Written reviews complicate that: 40% of Levelgas's written reviews are positive against 25% of DuoSmart's, so the app with the better star average is not the one people write more warmly about.

Levelgas ships an update every 3 weeks, DuoSmart every 9 months. The most recent releases landed on August 15, 2026 and August 6, 2026 respectively.
