# Pace Watch vs RUN interval

The clearest difference is rating: RUN interval at 4.7 against Pace Watch's 3.8. RUN interval also leads on review sentiment (77% vs 50%) and ratings volume (1K vs 4). Pace Watch's advantage is in-app purchases (none vs 2) and update cadence (every 8 days vs every 3 months). On price, ads and device support there is nothing between them.

Both are free to download. RUN interval sells 2 one-off in-app purchases. Pace Watch asks for nothing beyond the download.

RUN interval holds the better App Store score, 4.7 against 3.8. That said, the two scores are not equally well evidenced: RUN interval has 1K ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 50% of Pace Watch's written reviews are positive against 77% of RUN interval's.

Pace Watch ships an update every 8 days, RUN interval every 3 months. The most recent releases landed on June 1, 2026 and September 25, 2026 respectively.
