# Treinus vs Cross CheckIn

The clearest difference is review sentiment: Treinus at 79% against Cross CheckIn's 38%. Treinus also leads on ads (none vs shown) and ratings volume (114 vs 1). Cross CheckIn's advantage is in-app purchases (none vs 1) and rating (5.0 vs 4.7). On price, update cadence and device support there is nothing between them.

Both are free to download. Treinus sells 1 one-off in-app purchase. Cross CheckIn asks for nothing beyond the download.

Cross CheckIn holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Treinus has 114 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 79% of Treinus's written reviews are positive against 38% of Cross CheckIn's, so the app with the better star average is not the one people write more warmly about.

Treinus ships an update every 3 weeks, Cross CheckIn every 2 weeks. The most recent releases landed on October 18, 2026 and October 4, 2026 respectively.
