Verdict
The clearest difference is monetization model: Interval Timer at free with in-app purchases against Instruct's subscription. Interval Timer also leads on update cadence (every 9 days vs every 2 months) and ratings volume (19K vs 5). Instruct's advantage is rating (5.0 vs 4.5) and ads (none vs shown). On price, in-app purchases, device support and iOS requirement there is nothing between them.
