Verdict
The clearest difference is review sentiment: Pst Mail at 71% against UniFi Design's 23%. Pst Mail also leads on ratings volume (41 vs 7) and iOS requirement (11.0 vs 18.0). UniFi Design's advantage is price (Free vs $9.99) and rating (5.0 vs 4.3). On ads, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
UniFi Design is free to download; Pst Mail costs $9.99 up front. Neither carries in-app purchases, so what you see is what you pay.
UniFi Design holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Pst Mail has 41 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 71% of Pst Mail's written reviews are positive against 23% of UniFi Design's, so the app with the better star average is not the one people write more warmly about.
Pst Mail ships an update every 5 months, UniFi Design fortnightly. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
