A guided 5-minute workout with completion tracking

Monthly subscription to access the workout library

## First acquisition channel
Short videos demonstrating the workout

## Observable validation criterion
10 people complete 3 workouts in a week and 3 agree to pay

## Outside the first version

A structured document from your answers, not market research, code generation, or demand evidence. Review assumptions with users.

How it works

Group answers into audience, pain, promise, scope, business hypothesis, distribution, and validation criterion.

Worked example

A workout app can start with one guided routine and measure weekly repetition before building a full library.

Assumptions and limits

Frequently asked questions

How do I use the app mvp brief builder?

Turn your audience, problem, core feature, pricing hypothesis, and channel into a copyable MVP brief. No AI or data uploads.

Does the brief define the full roadmap?

No. It outlines one small, testable hypothesis. Expansion depends on learning, not on the number of planned features.

Do I need an account and are my inputs uploaded?

No account is required. Calculations run in your browser. Entered numbers and text are not included in tool analytics events; only the tool ID, language, and action are recorded.

Want to go past the numbers and see the real market?

Noctral shows estimated MRR, live ads, creators, and competitors so you can validate opportunities with real signals instead of projections.
