About

Stack

Features
Read full description

Stack is a routine execution system for people who already know what they should be doing. You have a supplement stack. A skincare routine. A training programme. The problem isn't information, it's execution. Stack turns everything you already have into a clean daily checklist, then gets out of your way. IMPORT ANYTHING Paste your routine as raw text like notes, a WhatsApp message, a list, an AI summary. Stack reads it and builds your structured routine automatically. No templates. No manual entry. Just paste and go. TODAY VIEW Every block due today appears in one flat list, in order. Morning supplements. Evening skincare. Push day. You open the app, work through the list, and close it. That's the entire interaction. PROTOCOLS LIBRARY All your routines live in one place. Skincare, Supplements, Fitness, anything else. Each protocol shows how many steps are scheduled today and your current completion rate. Tap in to drill down to individual steps. HISTORY LOG Look back at any day. See exactly what you completed, what you skipped, and any notes you added. Useful for spotting patterns over time like realising you always miss Tuesday evening. INSIGHTS Weekly and monthly adherence charts with AI-generated analysis. Stack looks at your completion data across all protocols and surfaces specific, actionable observations, not generic encouragement. BUILT FOR PROTOCOL PEOPLE Stack is not a habit-building app. There are no streaks, no badges, no motivational quotes. It assumes you already have the discipline. It just removes the friction between knowing what to do and actually doing it. Works with any routine: supplements, skincare, training splits, mobility work, morning shakes, medication, meal prep. If it has steps, Stack can hold it. Dark and light mode. Notification reminders. Cloud sync across devices.
