Verdict
The clearest difference is in-app purchases: T1D1 Mobile at none against T1dApp's 7. T1D1 Mobile also leads on ratings volume (109 vs 1). T1dApp's advantage is update cadence (every 5 days vs every 2 months) and rating (5.0 vs 4.7). On price, ads, monetization model and device support there is nothing between them.
