# Rock Collector vs TrainClicker Idle Evolution

The clearest difference is ads: TrainClicker Idle Evolution at none against Rock Collector's shown. TrainClicker Idle Evolution also leads on update cadence (weekly vs every 3 weeks) and review sentiment (53% vs 44%). Rock Collector's advantage is rating (4.7 vs 4.4). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Rock Collector sells 10 one-off in-app purchases and TrainClicker Idle Evolution sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Rock Collector holds the better App Store score, 4.7 against 4.4. Both are backed by a comparable volume of ratings — 146 and 482 respectively. Written reviews complicate that: 44% of Rock Collector's written reviews are positive against 53% of TrainClicker Idle Evolution's, so the app with the better star average is not the one people write more warmly about.

Rock Collector ships an update every 3 weeks, TrainClicker Idle Evolution weekly. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
