Verdict
The clearest difference is rating: Trax4 at 4.0 against Flashcal+'s 2.3. Trax4 also leads on in-app purchases (none vs 5) and device support (3 vs 1). Flashcal+'s advantage is review sentiment (50% vs 20%) and update cadence (every 3 weeks vs every 4 months). On price, ratings volume, ads and monetization model there is nothing between them.

Trax4 holds the better App Store score, 4.0 against 2.3. Both are backed by a comparable volume of ratings — 11 and 6 respectively. Written reviews complicate that: 20% of Trax4's written reviews are positive against 50% of Flashcal+'s, so the app with the better star average is not the one people write more warmly about.
Trax4 ships an update every 4 months, Flashcal+ every 3 weeks. The most recent releases landed on September 13, 2026 and September 11, 2026 respectively.
