Email, by voice. Lumin is a voice-first email assistant for your iPhone. Tap once, talk to it, and it reads, replies to, deletes, and triages your email — without you having to look at a screen. Designed alongside the blind and low-vision community. Useful for anyone who'd rather work with their voice than their thumbs. What you can do • Triage your morning inbox — "What's new?" and Lumin reads through your unread mail, one by one. Say "delete," "archive," "mark as read," "reply," or "next." • Write replies by voice — Dictate naturally. Lumin writes professional, full-sentence emails that don't sound like AI. Review before you send. • Find what you need — "Find the email from my doctor last week." Lumin searches your inbox and reads back what it finds. • Get the gist of a long email — "Summarize this." Lumin reads you the key points instead of the full message. • Hands-free, eyes-free — Works while you're making coffee, walking the dog, or anywhere you don't want to stare at a screen. Built for accessibility Lumin is designed to work alongside VoiceOver — or to replace the parts of email that VoiceOver makes painful. No more swiping through subject lines. No more wrestling with HTML emails. Just talk. Privacy Your email stays yours. Lumin only reads what you ask it to read, and only writes when you tell it to. We never sell, share, or train on your inbox content. Built by Luminade Inc. in San Francisco.

Verdict
The clearest difference is update cadence: Lumin at weekly against SmartCE's every 33 months. SmartCE's advantage is device support (3 vs 1) and iOS requirement (11.0 vs 18.6). On price, ads and in-app purchases there is nothing between them.
