Verdict

The call

The clearest difference is ratings volume: RUN interval at 1K against Yollo's 15. Yollo's advantage is rating (5.0 vs 4.7) and update cadence (every 4 weeks vs every 3 months). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. RUN interval sells 2 one-off in-app purchases and Yollo sells 2 in-app purchases, starting at $39.99 per year. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Yollo holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: RUN interval has 1K ratings behind it against 15, so its average is the more settled of the two. Written reviews complicate that: 77% of RUN interval's written reviews are positive against 74% of Yollo's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

RUN interval ships an update every 3 months, Yollo every 4 weeks. The most recent releases landed on October 9, 2026 and October 8, 2026 respectively.
