PACT
Read full descriptionHide full description
PACT is a minimalist focus timer built on a single, uncompromising idea: a commitment you either keep or consciously break. β THE EXCEPTION SYSTEM: ZERO EXCUSES What makes PACT radically different is how it handles interruptions. You cannot simply pause the timer and walk away. Every break in focus forces a permanent choice: β’ Allow an Exception: You can pause, but your reason becomes a permanent rule for all future sessions. What you allow once, you must allow forever. Your exceptions define who you are as a focuser. β’ Break the Pact: Surrender entirely, and your accumulated chain instantly resets to zero. There is no neutral option. Over time, your exception rules build an honest, unforgiving record of how you actually work β not how you think you do. β DESIGNED FOR DEEP WORK β’ Pre-Commitment Buffer: Reserve a session in advance. A timed countdown gives you a moment to sit down, complete your start ritual, and mentally prepare before the timer locks in. β’ Visual Accountability: Every completed session adds an unbreakable link to your chain. Watch it grow. Protect it at all costs. β BUILT FOR PURE FOCUS PACT is intentionally minimal. β’ No social feeds. β’ No gamified streak animations. β’ No meaningless badges or rewards. Just you, your word, and the timer. β SEAMLESS EXPERIENCE β’ System-adaptive Light and Dark modes designed to blend into your workflow. β’ Fully localized in English, δΈζ (Chinese), FranΓ§ais (French), and ζ₯ζ¬θͺ (Japanese). PACT is for people who take their commitments seriously. Make the pact. Keep it.

You know what to do. The hard part is starting, switching, and knowing when your brain will actually cooperate. Tempo learns those patterns β your energy rhythms, your real transition costs, your reliable focus windows β and hands them back as concrete daily guidance. Built for adults with ADHD. 100% on your iPhone: no account, no cloud, nothing uploaded β the privacy label reads "Data Not Collected". WHY TEMPO IS DIFFERENT Most productivity apps hand you a to-do list and assume that starting, switching, and landing on time are free. For ADHD brains, those are the whole game. Tempo doesn't ship generic templates or streaks β it learns how one specific brain works: yours. A MORNING ENERGY FORECAST Last night's sleep, heart rate variability, resting heart rate, today's calendar β even the tone of your recent journal entries β become one honest capacity score β with the "why" behind it, so you plan the day you actually have, not the day you wish you had. TRANSITIONS THAT LAND Tempo learns how long switching really takes you β after deep work ~15 minutes, after a walk ~5 β and counts down on your Lock Screen: "Standup at 14:00 β start wrapping up around 13:40." Small, concrete micro-actions you can edit make the switch real: close your tabs, water, phone on silent. ONE-TAP CHECK-INS After an event ends: "How did that go?" Energizing, draining, hard to start β one tap, five seconds, straight from the notification. Always skippable, capped per day, silent during your quiet hours. No streaks, no guilt. PATTERNS WITH RECEIPTS "After a short night, meetings feel draining 80% of the time." Every insight is computed from your own data, shows its evidence count and confidence, and never appears until it's statistically real. Never noise, never astrology. AND MORE β’ A gentle nudge when you've been deep in one thing past your planned length β water? snack? β’ A searchable evening journal that finds tone, themes, and blockers β analyzed on-device β with your sessions and check-ins on one day-by-day timeline β’ One-tap decision logging β name the ones that cost you, and spot your decision-heavy days β’ Home Screen widgets: Daily Forecast, Next Hours with readiness scores, and your journal rhythm β’ A monthly report that reads like a friend explaining your month β’ Light and dark themes with six calm accent colors, in 10 languages PRIVACY, FOR REAL No server. No account. No analytics, no trackers, no third-party code. Everything β including the AI β runs with Apple's on-device intelligence. Export it all as one JSON file, import it back on a new iPhone, or erase it all, any time. Your patterns are nobody's business. FREE AND PRO Free forever: session tracking, one-tap check-ins, your schedule with wrap-up times, weekly stats, and 14 days of history. Tempo Pro adds the morning energy forecast, pattern insights, transition Live Activities, journal analysis, readiness on widgets, the monthly report, and unlimited history β as a monthly or yearly auto-renewing subscription (7-day free trial) or a one-time lifetime purchase. Payment is charged to your Apple Account at confirmation of purchase. Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the end of the current period. Manage or cancel any time in your App Store account settings. Tempo is a self-knowledge and routine-support tool. It does not diagnose, treat, or replace professional care.

Verdict
The clearest difference is in-app purchases: PACT at none against Tempo's 3. PACT also leads on iOS requirement (15.1 vs 26.0). On price, ads and device support there is nothing between them.
