Verdict

The call

The clearest difference is price: Autodesk Fusion at Free against Pst Mail's $9.99. Autodesk Fusion also leads on ratings volume (4.1K vs 41) and update cadence (monthly vs every 5 months). Pst Mail's advantage is review sentiment (71% vs 60%) and iOS requirement (11.0 vs 13). On rating, ads, in-app purchases and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Autodesk Fusion holds the better App Store score, 4.5 against 4.3. That said, the two scores are not equally well evidenced: Autodesk Fusion has 4.1K ratings behind it against 41, so its average is the more settled of the two. Written reviews complicate that: 71% of Pst Mail's written reviews are positive against 60% of Autodesk Fusion's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Pst Mail ships an update every 5 months, Autodesk Fusion monthly. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
