Every account in one inbox — and Airo does the sorting. Airo reads every email and proposes what to do with it: archive, trash, star, reply. You approve a hundred at once, or veto the ones it got wrong. Nothing moves without your okay. TEN ACCOUNTS, ONE INBOX Read every Gmail and Google Workspace account together, in one list, with one set of gestures. No more thumbing between apps or logging in and out to find the email you half-remember. Screen new senders, block the ones you don't want, snooze what can wait, and schedule sends for later. THE APPROVE-OR-VETO INBOX Every email arrives pre-sorted and color-coded — shopping, finance, travel, social — with a suggested action already attached. Swipe to override any single one. Tap once to apply the rest. This is the whole app in one gesture. REPLIES THAT SOUND LIKE YOU Airo learns how you actually write and drafts in your voice, not a chatbot's. Read it, tweak it, send it — or ask for another take. IMPORTANT ON TOP, EVERYTHING ELSE BELOW Split Inbox puts mail that needs you at the top and parks the rest underneath. Pin any label, category, or filter as its own split. ASK YOUR INBOX A QUESTION "What did the landlord say about the lease?" "Show me my last utility bill." Plain English, instant answer. UNSUBSCRIBE IN BULK Airo finds every list you're on and unsubscribes from as many as you want in one pass. NO ADS. NO DATA SALES. AES-256 encryption. AI vendors never train on your mail. That's the entire privacy policy in three lines. Airo works with Gmail and Google Workspace accounts. SUBSCRIPTIONS Try Airo free for 7 days.

Read full description

Write Once is a minimal daily writing app built around one simple idea: one blank page, once a day. Start a session and write freely for fifteen minutes. There are no feeds, prompts, streak pressure, or public profiles. The timer stays out of the way so you can focus on the page. Your writing is stored locally on your device. Use Write Once to clear your head, build a small writing habit, or capture whatever is on your mind before the day moves on.
