Verdict

The call

The clearest difference is in-app purchases: GRIT at none against Interval Timer's 8. GRIT also leads on ads (none vs shown) and update cadence (every 2 days vs fortnightly). Interval Timer's advantage is device support (4 vs 2) and iOS requirement (15.0 vs 18.0). On price there is nothing between them.
