Verdict
The clearest difference is rating: Circuit Tools at 4.5 against OnTrack's 3.3. Circuit Tools also leads on in-app purchases (none vs 2) and iOS requirement (10.0 vs 18.6). OnTrack's advantage is review sentiment (37% vs 0%) and update cadence (every 4 weeks vs every 5 months). On price, ratings volume, ads and device support there is nothing between them.

Both are free to download. OnTrack sells 2 in-app purchases, starting at $3.99 per month. Circuit Tools asks for nothing beyond the download.
Circuit Tools holds the better App Store score, 4.5 against 3.3. Both are backed by a comparable volume of ratings — 30 and 55 respectively. Written reviews complicate that: 0% of Circuit Tools's written reviews are positive against 37% of OnTrack's, so the app with the better star average is not the one people write more warmly about.
Circuit Tools ships an update every 5 months, OnTrack every 4 weeks. The most recent releases landed on October 4, 2026 and October 11, 2026 respectively.
