Karico is the workout log you always wanted: fast during your session, honest about your progress, with just enough game to keep you consistent. AT THE GYM, ZERO FRICTION • Ready-made or custom plans with sets, rep ranges and rest times • Log every set in two taps: weight moves in your machine's real increments, no keyboard • Machine busy? Skip ahead and come back later • Rest timer always visible, even on the lock screen • Karico remembers your last performance and tells you when to add weight THE JOURNEY (IF YOU WANT IT) An RPG-style map with 4 chapters and 200 levels. XP is earned one way only: by actually training. Every 5 levels a boss blocks your way with a real challenge — planks, pull-ups, running distance — and your journey resumes only when you defeat it. Medals, frames, titles and rewards to collect. Entirely optional: without the Journey, Karico is still your training app. CARDIO & NUTRITION • Active calories and steps read from Health, nothing to start • Food diary with barcode scanner and recipes • Weight goals and measurements, synced from Health (smart scales) YOUR GYM, YOUR COMMUNITY Connect to your gym: board, leaderboard and challenges with the people who train beside you. In public you only appear under your nickname. YOUR DATA IS YOURS Automatic cloud backup, restore on a new phone, one-tap export and deletion. Location and Health data never leave your phone. Karico Premium (optional subscription, monthly or yearly with a 7-day free trial) unlocks the pro tools: equipment variants, PDF reports for your personal trainer, AI export, meal routines, advanced stats and exclusive frames. Everything else is free, forever. Privacy Policy: https://hub.studioupweb.com/karico/privacy.html Terms of Use (EULA): https://hub.studioupweb.com/karico/termini.html

Pick your window (Oct 1 to Dec 31 is the classic), write the daily rules you refuse to skip, sign your name, and show up every single day. WRITE YOUR NON-NEGOTIABLES Up to 10 daily rules: train every day, 10k steps, no alcohol, read 10 pages, up before 6, no phone after 9pm. Yours, in your words. Tap a suggestion or type your own. SIGN THE CONTRACT A contract card with your rules, your dates and your signature. Post it before day one. Telling people is half the discipline. CHECK IN. LOCK THE DAY. Every day, check off each rule. All of them done = a perfect day and a streak. Miss one and the grid shows it. No hiding. WATCH THE ARC FILL UP A 92-day grid (or however long you set), perfect-day streak, best streak, rules hit rate, days left. Share the progress card whenever you want. BUILT FOR THE LONG HAUL - Optional daily reminder at the hour you choose - Works fully offline. No account, no sign-up, nothing leaves your phone - Any dates: Oct 1 to Dec 31, 90 days from today, Nov 1 to Jan 31, or your own - Available in English, German, Spanish, Portuguese, French and Italian Free to use, supported by a small ad on the progress screen.
