Tereré — an endurance coach with a mate in hand

What it is

Tereré is an iOS app for people who run, ride or swim for themselves, not for a podium. It reads your night, writes your day, and talks to you like a coach who has been at every one of your workouts.

MATE INDEX

One number for the morning, built from your sleep, heart-rate variability and resting pulse. Frozen for the day and explained in plain words: how much mate is in your gourd today.

A plan that lives on your watch

Running, cycling, swimming and strength, structured and re-tuned every morning to how you actually slept. It lands on your Garmin. You just press start.

A coach that knows your history

Every workout you have ever logged, every personal best with its date, every note you told it. Ask anything by voice. Move a session with one phrase.

Calories from a photo

Point the camera at your plate. Tereré names the dish, counts the calories and macros, and knows what an Argentine portion looks like. Speak the corrections, it listens.

Your day, honestly

Charge, strain, freshness and sleep debt from your watch, shown as words first and numbers second. No red alarms, no guilt.

Your data stays yours

Health data is processed only to coach you, never sold, deleted on request. Coordinates are rounded, voice is never stored. Built to European privacy rules from day one.

Who it is for

The amateur who trains for real

You run, ride or swim a few times a week, own a sports watch, and want a plan that adapts to your life instead of a PDF that ignores it.

The one who wants to eat honestly

You do not want to type ingredients. You want to photograph the plate, hear the number, and get one useful sentence about it.

The one who is tired of being shouted at

Streaks, red badges and "you missed a day" are not coaching. Tereré tells you the truth once, calmly, and moves the session.

Why it is called Tereré

Tereré is cold mate, the way it is drunk in the heat of Paraguay and northern Argentina: from a shared gourd, unhurried, passed from hand to hand. It is a drink for long afternoons and long conversations.

The app was born in Buenos Aires, where its founder trained and drank mate for years, and is now built on Tenerife, where he still runs, rides and swims with it. The gourd on the first screen is the one on his desk.

A good coach is like a good mate circle: it knows you, it does not rush you, and it tells you the truth without raising its voice.

Argentina is the first market, its flag is on the screen, and its kitchen is in the food recogniser. Other countries get their own colours.

Where it is now

Tereré is in private beta on iOS through TestFlight. Garmin and Apple Health are connected, the coach and the food recogniser are live, the new design is being rolled out screen by screen.
