Tempus is a calm daily planner built for ADHD brains — one clear timeline for your day, real app blocking for your focus, streaks that forgive, and a Siri that finally understands what you mean. MADE FOR REAL ADHD CHALLENGES Most planners assume your brain cooperates. Tempus is designed for the days it doesn't: • Time blindness — see time as space on a visual timeline • Task paralysis — describe your day and let Apple Intelligence draft the plan; you review it before anything is saved • Forgetfulness — alarms, smart reminders and Live Activities that meet you where you are • Overwhelm — one signal per state, one accent per screen. Nothing shouts. • Broken routines — streaks that forgive a day off, because coming back is the win PLAN — DESCRIBE YOUR DAY, THEN DECIDE • Say or type what needs to happen: "deep work this morning, gym after lunch, call the clinic" • Tempus turns it into tasks with a duration, a priority and an energy level, and fits them around what's already on your calendar • Watch the plan take shape on the timeline as it's written. Fix a title, drop what you don't want, then add it to your day. Nothing lands until you say so. • Plan today or tomorrow — from the app, or by asking Siri • Tasks, habits, routines, Apple Calendar (including the Google and Outlook accounts on your iPhone) and Reminders on one timeline • Inbox to capture thoughts now and sort them later ASK SIRI — IN YOUR OWN WORDS • "Plan my day in Tempus", "What's next in Tempus", "Start focus in Tempus" — ten Siri shortcuts, most of them without opening the app • On iOS 27, Apple Intelligence understands Tempus like a calendar: "Create a dentist appointment in Tempus tomorrow at 3pm" just works, with no phrase to memorize • Siri answers with cards you can act on — mark the next task done or start a focus session right from the card • Find any task in Spotlight and open it directly • With a task on screen, "Start focus in Tempus" starts on that one • Shortcuts for Prepare Tomorrow, Reschedule Task, Move Unfinished Tasks (with undo) and Review Day PROTECT — FOCUS THAT CAN'T BE STOLEN • Focus Mode blocks distracting apps with one tap, using Apple's Screen Time technology • The world dims until you're done — Live Activities keep the session on your Lock Screen • Timers, interactive widgets and Apple Watch support FORGIVE — PROGRESS WITHOUT PUNISHMENT • Streaks that forgive: a day with nothing planned never breaks your streak • Quiet statistics by week, month or year that celebrate coming back, not output • No confetti. No guilt. Just a calm acknowledgment and your next step. PRIVATE BY DESIGN • No account required. Your tasks live on your device and in your own iCloud. • With Apple Intelligence, planning runs on Apple silicon — where neither Apple nor Tempus can read your request • Where Apple Intelligence isn't available, Tempus's own planning service drafts the plan, and you still review everything before it's saved ALSO IN TEMPUS • iCloud sync across iPhone, iPad and Mac • Works offline • Home Screen and Lock Screen widgets, Live Activities, an Apple Watch app and complications • A native Liquid Glass interface, with a proper split view on iPad PERFECT FOR • Adults with ADHD or executive function challenges • Students managing classes, deadlines and revision • Professionals who need deep work without distractions • Anyone overwhelmed by traditional productivity apps Tempus is free to download. Tempus Pro unlocks the full experience, available monthly, yearly, or as a one-time lifetime purchase — stated once, no countdown timers. Requires iOS 26.2 or later. Planning with Apple Intelligence needs a supported device with Apple Intelligence turned on. Siri in your own words needs iOS 27.

Verdict
