Mailo
Native iOS and Android apps that send notes and links straight to your own Gmail inbox.
Mailo sends quick notes, links, and images straight into your own Gmail inbox using Gmail's insert API, without ever reading your existing mail.
Compose in the app or share from anywhere with the iOS Share Sheet or Android share menu. A local, device-only history tracks what you have sent. The native apps use SwiftUI on iOS and Kotlin with Jetpack Compose on Android. No backend, no analytics, and no cloud sync.
mailo.cpd.dev is the front door: one static page, no build step, carrying the product story, the support notes, and the privacy policy App Store review asks for. The first Mailo grew past the point where a tiny Gmail experiment could stay tiny, so v2 stays private: invite-only TestFlight on iOS and direct installation on Android. The insert scope needs OAuth verification before anything public, and small is the point.
