Verdict
The clearest difference is in-app purchases: TriAustria at none against Lactate Express's 4. TriAustria also leads on iOS requirement (15.0 vs 17.5). Lactate Express's advantage is update cadence (every 3 weeks vs every 6 months). On price, ads and device support there is nothing between them.
