A serious workout tracker with a deeply unserious companion.

Build the rat your training deserves.

Your training shapes him over time. Train legs and his legs grow. Ignore them long enough and that shows too.

Launch updates only. No spam, Rathaniel is annoying enough. Unsubscribe anytime. Privacy

Be there from Day One.

You’re on the waitlist.

Rathaniel, a tiny rat in his basement gym

Rathaniel, day one. Confidence pending.

Rathaniel after his physique has been shaped by consistent training

No visible levels. No fixed evolution.

Your rat becomes how you train.

Every muscle has to earn its place. The transformation takes weeks and months, not a lucky tap.

Same rat. Different evidence.

The joke stops at the training.

Under the rat is a serious workout tracker.

Log fast, follow your plan and get a clear recommendation for what comes next. Built around established strength training research and tuned to your own history.

Built to replace your workout tracker, not sit next to it.

The body has to be trained. The drip is up to you.

Before you join the pack

Fair questions.

What is SetNivo?

SetNivo is a strength training tracker that helps you log workouts and decide what to do next. The Gym Rat Companion gives that progress a personality of its own.

Are SetNivo’s recommendations research-informed?

That is the standard we are building toward. The recommendation system uses established strength training principles together with your own training history. We will be transparent about what is available as the product develops.

What is the Gym Rat Companion?

It is the rat tied to your profile. Its physique and behaviour will reflect how you actually train over time. The Companion never changes your training Prescription or gives you an unfair competitive advantage.

Is the Companion available now?

The training foundation is available in private preview. The native app and Companion system are in development, and the scenes on this page show the product direction rather than finished app footage.

Which platforms are planned?

SetNivo is being designed as a mobile app. Platform availability and release timing will be shared with the waitlist when they are ready.

What does joining the waitlist mean?

It means you have asked SetNivo to email you about launch and private-preview updates. It does not create an account or guarantee access, and you can unsubscribe at any time.

Can I pay to make my rat stronger?

No. Training earns the physique. Cosmetics may change what your rat wears, owns and can express, but they will never buy gains, League points or training status.

Your rat is waiting. Unfortunately, he is tiny.
