About

Stack

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.

About

July

July is a private, quietly beautiful period and fertility tracker. One glance tells you where you are in your cycle โ€” and nothing you log ever leaves your phone. You log one thing: the day your period starts. That's it. No symptoms to rate, no charts to fill in, no daily nagging. July does the rest. FREE, FOREVER โ€ข Today's status and the signature dot ring โ€” your whole cycle at a glance โ€ข One-tap period logging and complete cycle history โ€ข A clean calendar of past cycles and what's ahead โ€ข Gentle health flags worth mentioning to your doctor HONEST ABOUT UNCERTAINTY Bodies aren't calendars. July tells you when pregnancy is "possible," "less likely," or "unlikely" โ€” never a false guarantee. Every estimate is shown with a "~", because that's the honest way to talk about a prediction. TRULY PRIVATE โ€ข No account to create โ€ข No cloud โ€” everything is stored on your device โ€ข No ads, no analytics, no trackers, nothing to sell Optional end-to-end encrypted iCloud backup, only if you choose to turn it on. JULY LIFETIME โ€” ONE PAYMENT, NO SUBSCRIPTION Unlock the forecast curve and weekly ~chances, ovulation prediction, a doctor-friendly export, Home & Lock Screen widgets, and encrypted iCloud backup. Pay once โ€” it's yours forever. Subscriptions rot apps; we'd rather earn your trust. July is a tracker, not a doctor. It uses the dates you log to estimate your cycle and can't tell you for certain whether you can or can't become pregnant on any given day. For decisions about your health or family planning, please talk with a healthcare professional.
