# Engine Sounds vs RevApp

The clearest difference is review sentiment: Engine Sounds at 100% against RevApp's 0%. Engine Sounds also leads on rating (3.4 vs 2.0) and in-app purchases (none vs 2). RevApp's advantage is ads (none vs shown) and update cadence (fortnightly vs every 3 months). On price there is nothing between them.

Both are free to download. RevApp sells 2 one-off in-app purchases. Engine Sounds asks for nothing beyond the download.

Engine Sounds holds the better App Store score, 3.4 against 2.0.
