# PRO TREK Connected vs Twelve O'clock

The clearest difference is review sentiment: Twelve O'clock at 91% against PRO TREK Connected's 48%. Twelve O'clock also leads on update cadence (every 3 weeks vs every 2 months). PRO TREK Connected's advantage is in-app purchases (none vs 1) and rating (4.6 vs 4.4). On price, ads and device support there is nothing between them.

Both are free to download. Twelve O'clock sells 1 one-off in-app purchase. PRO TREK Connected asks for nothing beyond the download.

PRO TREK Connected holds the better App Store score, 4.6 against 4.4. Both are backed by a comparable volume of ratings — 345 and 83 respectively. Written reviews complicate that: 48% of PRO TREK Connected's written reviews are positive against 91% of Twelve O'clock's, so the app with the better star average is not the one people write more warmly about.

PRO TREK Connected ships an update every 2 months, Twelve O'clock every 3 weeks. Both last shipped on October 24, 2026.
