Used by millions worldwide, our all-new email app protects your communications and has everything you need to easily manage your inbox.

Proton is privacy, guaranteed by end-to-end and zero-access encryption. • Unmatched protection — We offer strong phishing, spam, and spying/tracking protection for all your communications. Industry Leading Security Features Messages are stored on Proton Mail servers using end-to-end encryption at all times and are transmitted securely between Proton servers and user devices. This largely eliminates the risk of message interception. Zero Access to Your Email Content Proton Mail's zero access architecture means that your data is encrypted in a way that makes it inaccessible to us. Data is encrypted on the client side using an encryption key that Proton does not have access to. This means we don't have the technical ability to decrypt your messages. Open-Source Cryptography Proton Mail's open-source software has been thoroughly vetted by security experts from around the world to ensure the highest levels of protection. Proton Mail only uses secure implementations of AES, RSA, along with OpenPGP, while all of the cryptographic libraries used are open source. By using open-source libraries, Proton Mail can guarantee that the encryption algorithms used do not have clandestinely built-in back doors. Proton Mail in the press: “Proton Mail is a Gmail-like email system which uses end-to-end encryption, making it impossible for outside parties to monitor.” Forbes “A new email service being developed by a group who met at MIT and CERN promises to bring secure, encrypted email to the masses and keep sensitive information away from prying eyes.” Huffington Post Follow Proton on social media for all the latest news and offers: Facebook: /proton Twitter: @protonprivacy Reddit: /protonmail Instagram: /protonprivacy Our open-source code base: https://github.com/ProtonMail EULA: http://www.apple.com/legal/itunes/appstore/dev/stdeula

Verdict
The clearest difference is ratings volume: Proton Mail at 48K against Ruby's 1. Proton Mail also leads on chart position (#59 vs unranked). Ruby's advantage is rating (5.0 vs 4.8) and review sentiment (60% vs 46%). On price, update cadence, ads and in-app purchases 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
Both are free to download. Proton Mail sells 6 in-app purchases, starting at $5.99 per month and Ruby sells 6 in-app purchases, starting at $4.79 per month. Whichever you choose, the download price is not the number that matters.
Ruby holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Proton Mail has 48K ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 46% of Proton Mail's written reviews are positive against 60% of Ruby's.
Both ship on a similar rhythm, roughly every 10 days. The most recent releases landed on October 13, 2026 and September 30, 2026 respectively.
