Which platforms and devices are supported?
Lonzo is a mobile app, on Android today with iOS following. Get it on Google Play — that is also where you subscribe.
There's a web app too, for a desktop browser (it works best in Chrome). You can sign in to it on either plan. What Lonzo Agenda doesn't include is sync: it's a single-device plan, so a phone and a browser aren't kept in step with each other. Sync across devices is part of Lonzo Assistant.
The AI work runs on our servers, not on your phone, so every supported device gets the same quality — a budget phone classifies your mail exactly as well as a flagship. Your device needs a network connection to do new work; an offline device still shows your last-synced Agenda.
What you need: Android 8.0 (Oreo) or later, and a Google account. For the web app, a current version of Chrome, Edge, Safari, or Firefox.
