Stop procrastinating on the big thing. Belay is an AI to do list and daily planner that breaks it into small steps and hands you the first one. You already know what you should be doing. That is not the problem. The problem is that it is one enormous thing, and no part of it looks small enough to pick up right now. Tell it what you keep putting off: finish the thesis, do the tax return, find a new flat. Belay turns it into three to five small steps, and the first one is always something you can do immediately: no preparation, no decisions, nobody else involved. Just the thing that starts it. Try your first breakdown before you create an account. MADE FOR BRAINS THAT STRUGGLE TO START Belay is an ADHD friendly planner, built with adults with ADHD and executive function difficulties in mind, and for anyone who knows what to do and still cannot begin. THE NEXT STEP, NOT THE PILE Belay shows you one step at a time. The rest are there, dimmed, so you can see the shape of the thing without carrying all of it. Finish one and the next arrives. Still too big? Break that step down again. Stuck on it? Tell the AI coach what is in the way (it is vague, there is no time, there is no energy, you do not know where to start) and get one concrete thing to do about that specific problem. THE ZEN ROOM Pick a step and do it with nothing else on screen: a breathing guide and real recordings of rain, waves or a fire. A DAY THAT FITS Ask Belay to plan your day and it lays your remaining steps into the gaps around your real calendar, with room to breathe between them. Pick one step and say when you will do it, and Belay will remind you at that time, in your own words. WHAT BELAY WILL NOT DO No streaks. No points. Nothing that punishes you for a day you missed, and nothing that makes coming back cost more than staying away. YOUR STATE, NOT YOUR SCORE Connect Apple Health and Belay reads sleep, heart rate and steps to show how your body is doing today. How well you can start changes with how you slept. Your health readings stay on your phone: read on your device, shown on your device. The one exception is off by default and asked for separately: a single word noting that your sleep was short, so the coach can suggest lighter steps. Never a number. FREE, AND WHAT PRO ADDS The free plan gives you two active goals, three AI breakdowns a week, one "I'm stuck" a week, and seven days of history. Adding and editing steps by hand is unlimited, so you are never left unable to work. Belay Pro removes the limits and adds the coach's own ordering of your day, writing your plan into your calendar, backup and syncing across your devices, and your full history. Dark by default. Twelve languages. Everything you write can be exported, on either plan, whenever you want it. AN ACCOUNT IS REQUIRED You can try your first breakdown without an account. To keep using the coach after that, Belay asks you to sign in with Apple, with Google, or with an email address and a password. The account is what keeps your work when a phone is lost. You can delete it, and everything in it, from Settings at any time. SUBSCRIPTION DETAILS Belay Pro is offered as a yearly auto-renewing subscription, which begins with a 7-day free trial, or as a monthly auto-renewing subscription, which does not include a trial. Payment is charged to your Apple Account at confirmation of purchase. A subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period, and you can manage or cancel it at any time in your Apple Account settings. Any unused portion of a free trial is forfeited if you buy a subscription during the trial. Belay is not a medical device and does not diagnose, treat, cure or prevent any medical condition.
