The call

The clearest difference is review sentiment: T at 100% against RestOrTrain's 64%. T also leads on in-app purchases (none vs 4) and rating (5.0 vs 4.8). RestOrTrain's advantage is ratings volume (606 vs 2) and update cadence (every 4 days vs every 3 weeks). On price, ads, device support and iOS requirement there is nothing between them.
