75 days. Your rules. No excuses. Choose a 75-day protocol, customize it to fit your life, then lock it in and follow through. Start or continue with a proven challenge like Hard, 75 Medium, 75 Soft, or Her 75 — or build your own from scratch. Set the daily rules that matter to you: workouts, water, reading, nutrition, journaling, skincare, progress photos, or anything else you want to commit to. Each day, check off your tasks. This is a clean, focused tracker built for one thing: helping you complete 75 consecutive days of the habits you said would change your life. Choose your protocol: - Hard: Two workouts per day, one outdoors, plus water, reading, diet, no alcohol, and a daily photo. - 75 Medium: One workout per day with the core structure of a classic 75-day challenge - 75 Soft: A lighter version focused on consistency, movement, reading, water, and mindful eating. - Her 75: A wellness-focused protocol with movement, journaling, skincare, and weekly progress photos. - Custom: Build your own protocol from scratch. Add the habits, rules, and commitments that fit your goals. How it works Choose a protocol or start blank. Customize every rule until it fits your life. Lock it in for 75 days. Check off your tasks from the app or home screen widget. Built for discipline, not noise No guilt-driven notifications. No fake motivation. No 6 a.m. buzzes. Your daily tasks live on your home screen widget, ready when you are. The discipline stays where it belongs: with you. Why 75 days? One good day is easy. A week feels good. Seventy-five days changes your baseline. The reset rule keeps the challenge honest. You either complete the day or you start again. That clarity is what makes the commitment powerful. Designed for: - First-timers - Restarters. - Habit builders. - Anyone ready to spend 75 days becoming the version of themselves they keep meaning to become.
