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
The clearest difference is ratings volume: Tempus at 61 against MasterKey's 1. MasterKey's advantage is rating (5.0 vs 4.7) and iOS requirement (13.0 vs 26.2). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. MasterKey sells 2 in-app purchases, starting at $1.99 per month and Tempus sells 6 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.
MasterKey holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Tempus has 61 ratings behind it against 1, so its average is the more settled of the two.
