# WasTrans vs eRMT

The clearest difference is in-app purchases: eRMT at none against WasTrans's 14. eRMT also leads on review sentiment (33% vs 25%). WasTrans's advantage is update cadence (every 3 weeks vs every 2 months) and ratings volume (28 vs 6). On price, rating, ads and device support there is nothing between them.

Both are free to download. WasTrans sells 14 one-off in-app purchases. eRMT asks for nothing beyond the download.

WasTrans holds the better App Store score, 2.4 against 2.2. Both are backed by a comparable volume of ratings — 28 and 6 respectively. Written reviews complicate that: 25% of WasTrans's written reviews are positive against 33% of eRMT's, so the app with the better star average is not the one people write more warmly about.

WasTrans ships an update every 3 weeks, eRMT every 2 months. The most recent releases landed on September 17, 2026 and August 19, 2026 respectively.
