NOT EVERY TASK IS URGENT. Some things can wait — but shouldn't be forgotten. Changing bed sheets, renewing your passport, checking food expiry dates, calling your parents. They're not on your daily to-do list, but they still need to happen. What-Else tracks them so you don't have to think about them — until it's time. It's the to-do list for everything else. THE CONCEPT • Flexible Intervals Real life isn't a calendar. With "Smart Intervals" (e.g., Every 2 weeks), the next due date only sets after you actually complete the task. No stress if you're a day late—the schedule adjusts to you. • Precision When Needed Need strict dates? You can also schedule tasks for specific days (e.g., "Every Tuesday" or "1st of the month"). Or combine both—flexible intervals with calendar-specific dates in a single task. • Track Reliability with On-Time Rate Unlike apps that just show checkmarks, What-Else tracks whether you completed tasks on-time or late. See which routines you're great at and which need interval adjustments based on YOUR patterns, not guesswork. KEY FEATURES • Dual Scheduling: Combine flexible intervals with calendar-specific dates in one task (e.g., "Every 5 days" + "Every Tuesday"). Most apps force you to choose one approach—What-Else gives you both • On-Time Rate Tracking: See completion reliability percentages for each task, not just checkmarks. Identify patterns and adjust intervals based on real data • Widgets: See your task status directly on your Home Screen or Lock Screen • iCloud Sync: Seamlessly syncs between devices. No account required • Daily Overview Notifications: Get a summary of what's due today • Native Design: Built with SwiftUI for a smooth experience with Dark Mode and Haptic Feedback • iPad and Apple Watch Support • Siri Shortcuts: Automate your routines with voice commands PERFECT FOR • Household: Changing bed sheets, watering plants, deep cleaning the bathroom • Maintenance: Descaling the coffee machine, backing up photos, digital cleanup • Health: Replacing toothbrush, taking vitamins, washing hairbrushes • Life Admin: Renewing your passport, checking food expiry dates, annual subscriptions • Social: Calling parents, reaching out to old friends and so much more ... WHAT-ELSE PRO Upgrade to Pro to unlock: • Unlimited Tasks • Advanced Analytics: On-Time Rate trends, completion patterns, and historical context. Each completion records the interval at that time—providing true historical analysis when you adjust task schedules over time. • Premium Icons (90+ Symbols) • Timeline Navigation • Support for indie development PRIVACY FIRST • No Account Required. • No User Tracking. • Data stays on your device and private iCloud.
