Verdict
The clearest difference is rating: Winmail Reader at 4.5 against Msg Viewer Pro's 4.0. Winmail Reader also leads on ratings volume (256 vs 4) and price ($1.99 vs $4.99). Msg Viewer Pro's advantage is review sentiment (69% vs 50%) and update cadence (every 2 months vs every 4 months). On ads, in-app purchases, monetization model 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
Winmail Reader costs $1.99 and Msg Viewer Pro $4.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Winmail Reader holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: Winmail Reader has 256 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 50% of Winmail Reader's written reviews are positive against 69% of Msg Viewer Pro's, so the app with the better star average is not the one people write more warmly about.
Winmail Reader ships an update every 4 months, Msg Viewer Pro every 2 months. The most recent releases landed on September 23, 2026 and September 22, 2026 respectively.
