# COROS vs Lattice

The clearest difference is rating: COROS at 4.3 against Lattice's 3.4. COROS also leads on in-app purchases (none vs 3) and ratings volume (802 vs 25). Lattice's advantage is review sentiment (66% vs 54%). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. Lattice sells 3 in-app purchases, starting at $29.99 per month. COROS asks for nothing beyond the download.

COROS holds the better App Store score, 4.3 against 3.4. That said, the two scores are not equally well evidenced: COROS has 802 ratings behind it against 25, so its average is the more settled of the two. Written reviews complicate that: 54% of COROS's written reviews are positive against 66% of Lattice's, so the app with the better star average is not the one people write more warmly about.

COROS ships an update every 3 weeks, Lattice fortnightly. The most recent releases landed on November 6, 2026 and November 7, 2026 respectively.
