Verdict
The clearest difference is in-app purchases: Best Interval Timer at none against Fitsifu Timer's 2. Best Interval Timer also leads on review sentiment (89% vs 63%). Fitsifu Timer's advantage is ads (none vs shown) and update cadence (every 5 days vs every 12 months). On price, device support and iOS requirement there is nothing between them.
