Turn inbox time into a short, timed sprint. Start a sweep, race a calm countdown, and make fast keep-or-clear decisions — all on your device. This app never reads or syncs your mail. This app is a focus timer and triage coach, not an email client. It does not connect to any account and does not read, send, or sync your email. You run the timer here and clear messages in your own mail app. WHAT YOU CAN DO - Run timed inbox sweeps — pick a length, like a 10-minute sweep, and work against a quiet countdown - Build custom triage rules — your own quick decisions: delete, archive, reply, or defer - Keep a daily streak — gentle reminders help you clear your mailbox every day - See your pace — charts and insights show how fast you sort and how your focus grows - Work fully offline — no account, no sign-in, nothing to set up HOW IT WORKS 1. Set a sweep length and start the timer 2. Open your own mail app and clear messages using your triage rules 3. End the sweep, log your streak, and check your pace WHY THIS APP Email piles up when there is no finish line. A short, timed sweep gives inbox work a clear start and end, so triage feels calm and focused instead of endless. FULL ACCESS Custom rules, complete insights, extended history, and daily reminders are part of full access, available as a weekly or yearly plan or a one-time lifetime purchase. Start your first sweep today and make inbox time feel calm and finite. — LEGAL — Terms of Use: https://web-levi.web.app/terms Privacy Policy: https://web-levi.web.app/privacy-policy Support: tphuc.work@gmail.com

Verdict
The clearest difference is ads: Focus at none against Lumisera's shown. Focus also leads on update cadence (monthly vs every 3 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.
