# Proton Mail vs InvenTree

The clearest difference is review sentiment: InvenTree at 100% against Proton Mail's 47%. InvenTree also leads on in-app purchases (none vs 6) and iOS requirement (15.6 vs 17.2). Proton Mail's advantage is price (Free vs $7.99) and rating (4.8 vs 3.7). On update cadence, ads, chart position and device support there is nothing between them.

Proton Mail is free to download; InvenTree costs $7.99 up front. Proton Mail sells 6 in-app purchases, starting at $5.99 per month. InvenTree asks for nothing beyond the download.

Proton Mail holds the better App Store score, 4.8 against 3.7. That said, the two scores are not equally well evidenced: Proton Mail has 49K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 47% of Proton Mail's written reviews are positive against 100% of InvenTree's, so the app with the better star average is not the one people write more warmly about.

Proton Mail ships an update every 10 days, InvenTree weekly. The most recent releases landed on October 20, 2026 and October 10, 2026 respectively.
