Verdict
The clearest difference is rating: FastR at 4.4 against UAF Control's 3.3. FastR also leads on review sentiment (38% vs 0%) and ratings volume (290 vs 4). UAF Control's advantage is in-app purchases (none vs 2) and update cadence (every 2 months vs every 5 months). On price, ads, device support and iOS requirement there is nothing between them.
