About

Every day, you open six apps and stitch them together. A planner. A calendar. A timer. A sleep tracker. A focus app. A content feed. None of them know the others exist. AXIS is the stitch. One app that plans your day, schedules it on your calendar, holds you to the work, feeds you knowledge during your rests, and tracks your sleep debt so tomorrow is better than today. TODAY Three tasks, in order, already on your calendar. Each one chosen by an AI that read your goals last night and matched them against your energy windows, your sleep debt, and the hours you already gave away. Tap the first task. The screen turns black. The work begins. PLAN You speak one goal. The AI decomposes it into four weeks, this week, and today — with specific deadlines built from your available hours and your chronotype peak. Not "next week." Wednesday, April 30, by 6pm, because you have three free hours on Tuesday and two on Wednesday. LOCK IN Full-screen. Timer. A sound you chose is playing. An emergency exit exists — it costs a Face ID and goes in your weekly review. Every early exit is logged. The AI uses that data to calibrate your next session. RECOVER Five minutes. One card. A real idea — not a notification, not a feed. A neuroscientist's finding about what happens to your memory after one bad night. A decision framework used by people who make decisions for a living. The Stoic technique Marcus Aurelius wrote about when Rome felt like too much. One hundred fifty cards at launch. You scroll inside our walls, not theirs. BODY Sleep debt, calculated from your last seven nights and your chronotype target. Shown on the Today screen every morning. When your debt is over 90 minutes, AXIS reduces your Deep Work allocation and adjusts your schedule automatically. The alarm does not let you snooze — it asks you to breathe for 90 seconds, state your intention for the day, and walk to another room. Then it stops. THE DIFFERENCE The AI plans. Deterministic math schedules. Apple Calendar is the source of truth. HealthKit tracks sleep debt. Five apps, one spine. PRICING Free: Today, Plan, three locks per day, first 20 cards. Founding (one-time): US$49.99 — AXIS Pro for life, no renewal. Pro: US$14.99/month or US$99.99/year. Everything — unlimited locks, all 150 cards, all music categories, sleep tracking, cross-device sync. Most committed users choose annual. AXIS is not for everyone. It is for people who want to do more with their day and have given up on willpower as a strategy. Subscriptions: AXIS Pro is an auto-renewing subscription — US$14.99 per month or US$99.99 per year. Payment is charged to your Apple Account at confirmation of purchase. It renews automatically unless cancelled at least 24 hours before the end of the current period; manage or cancel in Account Settings.

Verdict

The call

The clearest difference is in-app purchases: Obsidian at none against AXIS's 3. Obsidian also leads on chart position (#116 vs unranked) and device support (3 vs 1). AXIS's advantage is update cadence (every 9 days vs every 3 weeks). On price and ads there is nothing between them.
