# TrainRox vs HYDROX

The clearest difference is review sentiment: HYDROX at 100% against TrainRox's 52%. HYDROX also leads on ads (none vs shown) and rating (5.0 vs 4.7). TrainRox's advantage is ratings volume (63 vs 4). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. TrainRox sells 6 in-app purchases, starting at $2.99 per month and HYDROX sells 4 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.

HYDROX holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: TrainRox has 63 ratings behind it against 4, so its average is the more settled of the two.
