Verdict
The clearest difference is in-app purchases: OpenHIIT at none against Exercise Timer's 3. OpenHIIT also leads on review sentiment (100% vs 73%) and rating (5.0 vs 4.8). Exercise Timer's advantage is ratings volume (1K vs 8). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. Exercise Timer sells 3 in-app purchases, starting at $4.99 per month. OpenHIIT asks for nothing beyond the download.
OpenHIIT holds the better App Store score, 5.0 against 4.8.

Both ship on a similar rhythm, roughly monthly. The most recent releases landed on September 25, 2026 and August 14, 2026 respectively.
