# Lemio vs Chassis.build

The clearest difference is update cadence: Chassis.build at every 4 days against Lemio's monthly. Chassis.build also leads on review sentiment (100% vs 80%) and rating (5.0 vs 4.8). Lemio's advantage is ratings volume (87 vs 1) and iOS requirement (17.0 vs 26.2). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Lemio sells 10 in-app purchases, starting at $8.49 per month and Chassis.build sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Chassis.build holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Lemio has 87 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 80% of Lemio's written reviews are positive against 100% of Chassis.build's.

Lemio ships an update monthly, Chassis.build every 4 days. The most recent releases landed on November 3, 2026 and October 31, 2026 respectively.
