WhoMail

Most email apps now quietly send your mail to a cloud AI β for summaries, smart replies, "priority" ranking. WhoMail doesn't. Your email never leaves your device for an AI service. Ever. WhoMail is a fast, genuinely private email app for iPhone, iPad and Mac that brings Outlook, iCloud, Fastmail, Yahoo and any IMAP account into one unified inbox. WHAT MAKES IT DIFFERENT β’ No cloud AI. Ever. Your messages aren't uploaded, summarised, scanned, or used to train anything. Anything that feels smart happens on your device. β’ Know your people. WhoMail builds a private picture of who you actually email β your reply times, how often you talk, your busiest hours, and a profile for each contact assembled from their own email signatures. No other inbox shows you this. β’ Push that stays blind. New Outlook mail arrives the second it's sent, even with the app closed β but our relay only ever learns "this mailbox got something." The sender and subject are fetched on your phone, by your phone. β’ One unified inbox across every account, or jump to any single mailbox in a tap. β’ Native and fast β opens, syncs and searches instantly, with a calendar built in. PRIVACY ISN'T A FEATURE HERE β IT'S THE DESIGN β’ No AI servers. No mail content on our servers. No tracking, no ads, no profile of you sold to anyone. β’ You sign in straight with your provider; your tokens stay in the device keychain. β’ Turn our push service off tomorrow and you lose nothing but a little speed. Supports Outlook / Microsoft 365, iCloud, Fastmail, Yahoo and standard IMAP. Built by Calligo IT. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
The clearest difference is in-app purchases: xCalendar at none against WhoMail's 2. xCalendar also leads on iOS requirement (13.0 vs 26.0). WhoMail's advantage is update cadence (every 3 days vs every 11 days). On price, ads and device support there is nothing between them.
