# Morpholio Trace vs 6F

The clearest difference is rating: Morpholio Trace at 4.7 against 6F's 4.2. Morpholio Trace also leads on ratings volume (11K vs 19). 6F's advantage is update cadence (every 2 days vs every 2 weeks) and review sentiment (87% vs 70%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Morpholio Trace sells 4 in-app purchases, starting at $4.99 per year and 6F sells 2 in-app purchases, starting at $2.49 per month. Whichever you choose, the download price is not the number that matters.

Morpholio Trace holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: Morpholio Trace has 11K ratings behind it against 19, so its average is the more settled of the two. Written reviews complicate that: 70% of Morpholio Trace's written reviews are positive against 87% of 6F's, so the app with the better star average is not the one people write more warmly about.

Morpholio Trace ships an update every 2 weeks, 6F every 2 days. Both last shipped on November 11, 2026.
