About 300 — Discipline Instrument

**Not a fitness app. A discipline instrument.** 300 is built for people who have decided to stop negotiating with themselves. It's a brutally simple contract: every single day, you complete your chosen number of push-ups and squats. No skipping. No modifications. No excuses. Choose your weight—from the INITIATE's 50 reps to the SPARTAN's 200, or the full **THE 300**: 300 push-ups and 300 squats daily. Lock yourself in for 30-day cycles. Watch the calendar fill with your decisions. **What you get:** - **The Pact:** Five difficulty tiers. Pick one. You're locked in for the full 30-day cycle. - **The Ledger:** A visual timeline of every day you fulfilled or neglected your commitment. See your discipline (and failures) laid bare. - **The Lock:** When you finish your reps, the app locks you out for 10 minutes. No distractions. No notifications. Sit in the silence you earned. - **Memento Mori:** A meditation view showing your life as a percentage. How many days have you lived? How many remain? Let that inform today. - **The Forge:** End-of-cycle verdicts. CRACKED. TEMPERED. FORGED. FORGED IN FIRE. PERFECT FORGE. Each streak is a badge earned through fire. - **Home & Lock Screen Widgets:** Carry your daily commitment on every screen. The contribution grid. The mortality counter. No escape. - **The Forge Wallpaper:** A full-year view of your discipline—365 dots, each one a decision you made. - **Daily Stoic Quotes:** Each morning, a passage to anchor your practice. **Built on Stoic principles.** 300 embraces memento mori—the practice of contemplating your mortality. You have a finite number of days. This app ensures you spend them consciously. **No subscription. No account. No tracking.** This is between you and the work. Open the app offline. Log your reps. Leave. **For the genuinely committed.** This isn't motivational. There's no celebration or virtual rewards. You get a simple calendar and the weight of your own choice. That's the design. The 300 is inspired by the ancient Spartans and the philosophical traditions of Stoicism. It's for people building character in the forge of daily discipline. _"The impediment to action advances action. What stands in the way becomes the way."_ — Marcus Aurelius
