MATS is your AI coach for running, cycling, and triathlon. It plans your training week by week, checks your training load every day, and rebuilds your plan when your daily life changes. Behind the AI coach are real elite coaches. Their training philosophy is built into every plan it creates for you. Do you train with your own coach? Then you can work together in MATS, with your calendar, chat, and all your data in one place. And if you simply want to record and analyze your training, youโ€™ll find everything you need in the same app. ### AI COACH - Tell it what changes: two extra hours on Sunday, a business trip, an illness. It checks your training load and adjusts your week accordingly. - Add your races. It plans your base, build, and peak phases around them, all the way through your taper. - Your readiness, based on HRV, resting heart rate, sleep, and your daily feedback, is factored into every recommendation. SMART TRAINER - Control your smart trainer directly from MATS - on your smartphone, tablet, or in your browser. Your intervals run at the planned power target without the need for a second app. You can even connect your Core sensor.

Your strength sessions are scheduled where they best fit into your endurance training week. CALENDAR & ANALYSIS - All your workouts in one calendar, synced with Garmin, Apple, COROS, Suunto, Zwift, and other platforms. You can also factor weather data and availability into your planning. - Connect MATS to your personal calendar. This lets you see training, work, and family commitments in one place and schedule your workouts around your actual week. - Track your threshold power, training intensity distribution, and training load with the MATS Score. - Determine your performance parameters conveniently from home with the diagnostic protocol.

Most habit trackers punish you for being human. Miss one day and your streak resets to zero, so you stop opening the app. GradeDays is different. Every day, grade your effort on each goal: A: crushed it B: solid effort C: showed up, and that still counts There's no all-or-nothing streak to protect. A hard day where you did the bare minimum is still a logged win. Consistency survives real life. FEATURES โ€ข Grade up to 9 goals a day across Professional, Personal, and Other categories, each with its own A/B/C definitions you set yourself โ€ข Daily GPA and all-time GPA, weighted by how important each goal is to you โ€ข Weekly pattern insights โ€” perfect weeks, goals you're consistently missing, and the day of the week you tend to skip โ€ข A calendar view of every goal's history, color-coded at a glance โ€ข Custom numeric metrics per goal (minutes exercised, pages read, anything you want to track alongside your grade) โ€ข Home screen and Lock Screen widgets showing today's GPA and streak โ€ข Works offline โ€” log your day without a connection, it syncs when you're back โ€ข A daily reminder so grading your day becomes a habit itself โ€ข Passwordless sign-in โ€” no password to remember, ever โ€ข Export your full history as CSV any time โ€ข Full dark mode support Built on the idea that momentum beats intensity: small, honest effort repeated daily gets you further than sporadic perfection. GradeDays just wants you to show up.
