# Onion Browser vs Winmail Viewer

The clearest difference is review sentiment: Winmail Viewer at 100% against Onion Browser's 42%. Winmail Viewer also leads on rating (4.7 vs 3.2) and update cadence (every 9 days vs every 3 weeks). Onion Browser's advantage is ratings volume (2.1K vs 19) and iOS requirement (15.0 vs 17). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Onion Browser sells 3 one-off in-app purchases and Winmail Viewer sells 4 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Winmail Viewer holds the better App Store score, 4.7 against 3.2. That said, the two scores are not equally well evidenced: Onion Browser has 2.1K ratings behind it against 19, so its average is the more settled of the two.
