Verdict

The call

The clearest difference is ratings volume: Intervals Pro at 14K against ExRelief's 3. Intervals Pro also leads on update cadence (weekly vs every 2 weeks) and iOS requirement (17.5 vs 26.2). ExRelief's advantage is rating (5.0 vs 4.8) and review sentiment (100% vs 85%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Intervals Pro sells 8 in-app purchases, starting at $2.99 per month and ExRelief sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
