Early access opening soon

Your training, nutrition and recovery.
One AI buddy.

tesr is a personalized, AI-powered fitness and nutrition buddy. It tells you what to train, what to eat and when to rest, and it adapts the plan as your body does.

Concept preview. Sample data shown; the app is in active development.

We believe your health data should work for you, not for advertisers. tesr is built local-first: your records live on your device, sync encrypted when you choose, and are never sold, shared or used to target you. From that private foundation, one clear answer emerges: what to do next.

Why fitness apps fail you.

Your watch counts your steps. Your apps count your food. And still, every plan you download is the same plan everyone else downloaded.

Generic, one-size-fits-all plans

Downloaded PDFs and static templates ignore your body, your schedule, your equipment and your history. They work for their average user, and you are not average.

Plans that never adapt

You get sick, travel, or life happens, and the 12-week plan you bought in January doesn't know or care. Without real-time adaptation, a plan is stale within days.

Data scattered everywhere

Steps in one app, meals in another, workouts in a third, and none of them talk to each other. Fragmented data means no synthesis, and no synthesis means no real guidance.

One app. Your whole routine.

tesr brings training, nutrition and recovery into a single adaptive buddy, powered by our proprietary AI engine and designed to make the plan bend to your life, not the other way around.

Meet your Buddy

A personalized 6-week training block generated for you at onboarding by our proprietary machine-learning engine, then renewed and re-tuned as you progress. Not a template. A buddy that knows you.

Train

Real-time workout tracking: a deep exercise library, built-in timers, personal-record detection and progress that updates as you lift.

Eat

AI-driven meal and macro adjustments, barcode scanning, fast search and a deep Indian food database, so logging a home-cooked meal takes seconds, not minutes.

Charge

A single daily readiness score from your sleep, recovery and training load, with the full "why" behind it, so you know whether today is a push day or a rest day.

Cycle tracking

Personal pattern cards built privacy-first: your cycle data is the strictest class of data in tesr and is treated that way from the ground up.

Local-first privacy

Your health records live on your device first and sync encrypted only when you choose. No ads. No data selling. No trackers. Ever.

Under the hood: tesr runs on a proprietary AI/ML planning engine combined with a local-first data architecture. The intelligence is scalable, and the privacy is structural, not a policy promise.

Built in Hyderabad, for the way India trains.

tesr is an initiative by TESR Technologies Private Limited, a private limited company incorporated in India.

Our mission is simple: everyone deserves a buddy that knows them, their body, their food, their constraints. Not a generic plan built for an imaginary average. We combine modern machine learning with a local-first architecture so that the guidance is personal and the data stays personal.

We're a small, focused team of engineers and designers building the product we wanted for ourselves, and shipping it with the privacy we demand from our own devices.
