Verdict
The clearest difference is in-app purchases: STF Kronos at none against Avena Health's 11. STF Kronos also leads on ads (none vs shown) and iOS requirement (13.0 vs 15.1). Avena Health's advantage is update cadence (every 6 days vs every 2 months) and ratings volume (4.4K vs 9). On price and device support there is nothing between them.
