75 days. One rule. Zero excuses. 75 Hard Transform Tracker is the simplest way to run your 75 day challenge: check off your tasks, take your daily pic, and watch the days stack up until you meet the strongest version of yourself. SEE YOURSELF CHANGE Most trackers give you checkboxes. We give you proof. A camera overlay helps you stand the same way every day, so your photos line up perfectly. Compare any two days with a before and after slider. When you finish, export all 75 photos as one time lapse video of your transformation. SHARE THE WINS Every completed day ends with a day card worth posting. Share it to your Instagram Story in one tap, or send your before and after and your time lapse anywhere. Your progress is the best motivation, for you and for the people watching you. DO IT YOUR WAY Run the original 75 Hard by the book: two 45 minute workouts with one outdoors, follow a diet, no alcohol or cheat meals, a gallon of water, 10 pages of reading, and a daily progress pic. Or personalize the tasks and do 75 Soft, 75 Medium, or your own version. What matters is 75 honest days. THE RULE THAT MAKES IT WORK Miss a task and the count resets to Day 1. The app holds the line so you do not have to negotiate with yourself. Already mid challenge? Pick your current day and keep going. BUILT FOR THE DAILY GRIND โ€ข Custom reminders for each task, plus a "1 hour left" warning before your day ends โ€ข Your day ends when you say it does. Night owls can set their own cutoff instead of midnight โ€ข The full 75 day grid, so you always see how far you have come โ€ข Daily notes to remember the hard days PRIVATE BY DEFAULT Your photos, notes, and log stay on your phone. No cloud, no ads, no trackers, no selling your data. Nothing is shared unless you tap share, and you can delete everything. Available in English, French, German, Spanish, Portuguese, and Italian. Free for 3 days, then subscription. Cancel anytime. This app is an independent challenge. It is not affiliated with, endorsed by, or connected to Andy Frisella or 75 HARD. The challenge is physically demanding. Talk to a doctor before starting.
