An AI inbox that triages itself, drafts in your voice, and follows up so you don’t have to remember to. ORGANIZE EMAILS YOUR WAY Upstream sorts, flags, and surfaces what needs your attention today. Noise gets filed away. No rules to set up or folders to maintain. It learns how you work and gets out of your way. DRAFTS IN YOUR VOICE. NOT A VOICE. Upstream writes like you. Not like AI pretending to be you. It studies how you write, how you talk to this specific person, and what the thread already sounds like, then drafts from there. The reply is waiting before you've finished reading the email. THE FOLLOW-UP WRITES ITSELF Upstream watches the threads going quiet, writes the nudge, and adds it to your inbox to send. The open loops close themselves. The ball never gets dropped.

About

Margin

Read full description

Margin is a calm, beautiful planner for people who think in sentences, not forms. Type “dentist tomorrow 4 to 5” or “lunch with Sara Friday at 1” and Margin reads the day, the time, the list and even the repeat, then saves it to Apple Calendar or Reminders. It reads Arabic too, so you can write your day in either language. YOUR DAY, HOUR BY HOUR Every hour gets the same space, so you see where the time goes at a glance. Each hour tells you what is inside, meetings are drawn at their real minutes, and the current hour carries a live line through it. Tap an hour to open it and tick things off, or drag a task to another hour. FOCUS THAT FOLLOWS YOU Start a pomodoro or a simple timer and give it a name. It runs on your Lock Screen and in the Dynamic Island, where you can pause it or add five minutes without unlocking. Your timers stay in step between iPhone, iPad and Margin for Mac through your own iCloud: start on one, pause on another. MORE ROOM ON IPAD On iPad your day sits beside the month, the next few things and your undated tasks, with a week view and keyboard shortcuts. ON YOUR WRIST The Apple Watch app shows the hour you are in and what comes next, with your running timer on top. Say a task and it lands on your iPhone. WIDGETS AND SHORTCUTS Home Screen and Lock Screen widgets show now and next, your coming hours and your focus timer. Add to Margin with Siri, the Action button or a Control Center control. PRIVATE BY DESIGN No account, no ads and no tracking. Your plans live in your own Apple Calendar and Reminders, and timers sync through your own iCloud. One purchase. No subscription.

Margin's advantage is update cadence (daily vs every 2 weeks) and chart position (#198 vs unranked). On ads, in-app purchases and device support there is nothing between them.
