Everything in one routine

From the first plan
to the next milestone.

What Fitaio does, built around the way you actually train. Pick where you want to begin.

01 / Fitaio

A coach that has read your log

Ask for a training plan or a meal plan, get a review of your last weeks, or just ask a question. The coach works from your logged weight, goal pace, top sets and macros, and every suggestion is yours to check and edit.

  • Weekly plans. Describe your goal and your days; get a plan you can follow, revise or import from text.
  • Meal plans. Calories and protein planned for your target.
  • Progress reviews. A plain reading of how weight, training and macros are moving.

Log every set as you go

Follow today’s plan, reuse a saved routine or build a workout on the spot. Fitaio shows what you lifted last time, times your rest and does the plate math.

  • Previous performance. Your last numbers next to every set.
  • Rest timer. Starts when you finish a set, with your own default length.
  • Plate calculator. Plates per side for any barbell load.

For builders

Your data, your tools

Every workout, weight entry and nutrition day is reachable through a REST API with personal keys you create in the app. The MCP server exposes 22 tools, so Claude, ChatGPT, Cursor or VS Code can read your training and log on your behalf. Scripts written for Hevy’s api-key header work here too.

Good to know

Questions, answered.

A few things to know before you start.

Is Fitaio free?

Yes. Every feature is free with no ads and nothing to unlock. The web app is open now; the iPhone and Android apps are coming to the stores.

Which platforms does it run on?

The web app runs in any modern browser at fitaio.app/app and can be installed to your home screen. Native iPhone and Android apps are in preparation.

Does the AI coach replace a real coach?

No. It drafts plans, meal plans and reviews from your own log so you have a starting point to check and adjust. It is not medical advice.

Can I export my data?

Yes. Create an API key on the Developer screen and pull workouts, body metrics, nutrition and plans as JSON, or connect an AI assistant through the MCP server.

How do I delete my account?

Request it from Settings in the app or from the website. We verify you own the account, then delete it, your records and your uploaded photos.

Does it work offline?

The web app opens offline thanks to its cached shell, but logging and syncing need a connection.
