RETO100 is a 100-day program that builds real discipline, with daily missions across four areas: Cuerpo, Conciencia, Conexión and Capital. Every morning you open the app and see your missions for the day. The rule is simple and it does not forgive: the day is won or it is lost. That is what installs the habit. WHAT YOU FIND INSIDE Access to the app and all of its features requires an active subscription (RETO100 Pro). • Daily missions: training, steps, water, sleep, reading, meditation, prayer, journaling, fasting, nutrition and the ones you define yourself • Your goals, your plan: you set an objective and the app builds the daily missions to get you there • The 100-day path: your progress day by day, no shortcuts • An honest score: to win the day you have to complete your missions and touch all four of your areas • Nutrition: log meals, scan the barcode and track calories and macros • Training: guided routines with sets, reps and rest • Community: the live pulse of the challenge, a weekly leaderboard and direct messages with other challengers • AI coach: answers your questions and gives you a daily read on how you are doing • Apple Health: steps, sleep and workouts sync on their own • Widget and Apple Watch: your day at a glance, without opening the app WHO IT IS FOR For anyone who has tried to change before and slipped back after two weeks. RETO100 is not a magic fix: it is a daily structure that stays with you for 100 days straight, until the habit stops depending on how you feel. THE 4 AREAS Cuerpo, Conciencia, Conexión and Capital. A perfect day is not doing many missions from a single area: it is touching all four. The app measures it that way and tells you straight. SUBSCRIPTION Access to RETO100 and all of its features, including the AI coach, the training routines, the progress journal and nutrition logging, requires a subscription (RETO100 Pro), with a free trial for new users. There is a monthly plan and an annual plan; the price for your region is shown inside the app before you confirm the purchase. The subscription renews automatically unless you cancel at least 24 hours before the end of the current period. You can manage or cancel it at any time from your Apple ID settings.
