Verdict
The clearest difference is in-app purchases: Libre Fasting at none against Fasty's 3. Libre Fasting also leads on update cadence (every 3 months vs every 9 months). Fasty's advantage is ratings volume (1.5K vs 2) and rating (4.7 vs 4.5). On price, ads, device support and iOS requirement there is nothing between them.
