Verdict
The clearest difference is in-app purchases: FlexFit at none against SisuLift's 2. FlexFit also leads on ads (none vs shown) and iOS requirement (13.0 vs 15.0). SisuLift's advantage is update cadence (every 5 days vs every 24 months). On price and device support there is nothing between them.
