The coach for people coaching themselves.

Why we're building FitNav

Every fitness app on the market today follows the same pattern: a database, a barcode scanner, twelve tabs, and a "diary" you have to remember to fill in. They treat tracking as the goal. The result is millions of half-abandoned accounts and a lot of guilt.

We think the real goal is coaching. Most people don't need more data — they need someone to tell them what to do with it. They need a coach who remembers them between sessions, adapts when the plan stops working, and answers questions in plain English.

That's what FitNav is: a coach you can talk to — we call ours Kai. One chat window. Memory that lasts. Targets that adapt. Photo logging for when typing feels like too much.

How FitNav is different

• Conversation, not forms. If you can text a friend about your dinner, you can use FitNav.
• Memory that lasts. Kai remembers your preferences, schedule, injuries, and life context — for good, not just one session.
• Adaptive, not static. If your weight trend doesn't match your goal, Kai catches it and proposes adjustments.
• No ads. No data sold. A simple, honest $9.99/month subscription funds the AI costs. That's the whole business model.

The promise

• We will never show you ads.
• We will never sell your data.
• The free tier will always have the core coaching, logging, and memory.
• If we shut down, we will give you 30 days notice and an export of all your data.

Built by

FitNav is built by a small, independent team that uses it daily. We're starting with a tight waitlist beta so we can listen carefully and ship the right thing.
