No sign-up. No ads. No subscription. No questionnaire flow.
Just download and start logging your workouts, meals, and measurements in a simple and elegant UI.

Most apps lock features behind a paywall, bombard you with ads or subscription requests, and demand you share your personal data. If you want complete flexibility and privacy for your fitness logs, Cofit is built for you.

Cofit is a complete, private, and fully free fitness tracker for people who want full control over their training, nutrition, and body metrics in one app. No cloud required. No personal data collected. Everything runs 100% offline, on your device. Android's built-in backup keeps your data safe in your default Google account if you switch phones.

🏋️ Workouts, built your way

Cofit comes loaded with 1,000+ exercises and lets you build fully custom workouts with text instructions, images, and videos — including YouTube links. Log simple sets, supersets, and drop sets. Track your history, watch your personal records climb, and use the built-in rest timer to stay focused between sets. Duration estimates based on your past sessions help you plan smarter.

🥗 Nutrition that goes deeper than calories

Most apps track calories and maybe macros. Cofit tracks micro and macro nutrients, and even substances like toxins and drugs present in food — powered by USDA data. With 400+ substances and 330+ ingredients bundled, and the ability to create your own, you get precision most apps don't offer at any price. The database is actively growing, with more ingredients and substances being added regularly.

📏 Metrics beyond the scale

Most fitness apps limit you to a handful of fixed metrics like weight and height. Cofit takes a different approach: its flexible design lets you log any measurable metric — body composition, blood exam results, enzyme activity, energy levels, and more — in any unit system (US, UK, SI). Group them into full checkups and track trends over time. If it can be measured, Cofit can track it.

📅 Schedule everything, miss nothing

Plan workouts, meals, and measurements with recurring schedules and reminders. See your full day at a glance — what's planned, what's done, and how your nutrition stacks up against your targets.

📋 Programs for every goal

Build programs that combine workouts, meals, and measurements into a complete plan. Whether you're bulking, cutting, or just getting consistent, switch between programs easily and see summaries of average calories, macros, and training hours at a glance.

Why Cofit, and not the others?

Cofit is not the app that holds your hand through a quick setup flow and auto-generates a plan for you. If that's what you need, there are other apps for that.

Cofit is for people who want to build their own system. The bundled workouts, meals, and programs are starting points and examples — not a rigid framework. You decide what to track, how to track it, and what matters to you. That flexibility is the point.

And unlike most "free" apps, there's no freemium trap. Core features are free, forever. Donations are welcome but never required.

A note for runners

Cofit doesn't currently support step tracking, GPS routes, or smartwatch integration. If those are dealbreakers for you, it's worth knowing upfront. Those features are planned but will take a while.

Coming soon

Cofit is in active development and more features are on the way: smarter workout load suggestions, goal tracking, feed customization, gym equipment management, improvements to charts and data visualization, and support for more platforms including iOS. The foundation is solid, and it's getting better fast.
