Verdict
The clearest difference is in-app purchases: Fuel Lock Device Simulator at none against Libra Harvest's 3. Fuel Lock Device Simulator also leads on iOS requirement (11.0 vs 13.0). Libra Harvest's advantage is update cadence (every 3 weeks vs every 6 months). On price, ads and device support there is nothing between them.
