Tempo

Life doesn't follow a schedule. Tempo does. Tempo is a smart daily planner that automatically adapts your schedule when real life interrupts. Late start? Back-to-back meeting ran long? Unexpected task dropped in your lap? Tempo quietly reshuffles your day so your priorities survive, your habits hold, and nothing important gets lost. **Your tasks, ranked by what matters** Tempo organizes everything you need to do into four clear tiers: - Non-Negotiable ā fixed commitments that never move (meetings, classes, appointments) - Identity Habits ā the daily practices that define who you are (workouts, journaling, reading) - Flexible Tasks ā important work that can shift when needed - Optional Goals ā aspirations that flow around everything else When your day runs over, Tempo knows exactly what to protect and what to rearrange. **Intelligent conflict resolution** Add a new task and it overlaps with something already scheduled? Tempo instantly suggests the best resolution ā move the new task, shift the existing one, or keep both with a clear view of the overlap. You decide. Tempo executes. **Habits that survive a bad day** Most planners let habits disappear when life gets busy. Tempo compresses identity habits to their minimum useful duration rather than dropping them entirely. A 60-minute workout becomes a 15-minute session. Your streak stays alive. **Calendar import** Pull your Apple Calendar events directly into Tempo as non-negotiable tasks. Your existing commitments land exactly where they belong, automatically protected from being overwritten. **Recurring tasks built in** Set tasks to repeat daily or weekly. Tempo handles the scheduling automatically, resolving conflicts across recurring and one-off items together. **Timeline view** See your entire day at a glance on a clean hour-by-hour timeline. Overlapping tasks display side by side. Open gaps show exactly how much time you have to fill. The current time indicator keeps you anchored in the present. **Private by design** Everything stays on your device. No accounts, no servers, no cloud sync, no ads. Your schedule is yours. --- **Why Tempo?** Most planners are just lists. Tempo understands that a schedule is a living thing ā it bends, compresses, and recovers. It helps you end every day having protected what matters most, even when the day tries to take it all away.
