Verdict
The clearest difference is rating: AMT at 5.0 against Olypsys Measure's 3.2. AMT also leads on in-app purchases (none vs 3) and update cadence (every 6 days vs every 4 weeks). Olypsys Measure's advantage is ratings volume (6 vs 1). On price, ads and iOS requirement there is nothing between them.
