Coming soon · iOS & Android

One coach for training, food, and the recomp you actually want.

FitNav is built for self-coached people cutting fat or chasing a recomp — tired of juggling MyFitnessPal, a workout app, and a spreadsheet. Meet Kai, your coach: one chat that knows your whole week — today's leg day, last night's dinner, and what to eat next.

Why FitNav

ChatGPT writes you a routine. FitNav watches you do it.

Every other app knows one slice of you — what you ate, or what you lifted. FitNav connects them. Today's leg day, this morning's macros, where you stand on the cut. One coach. The whole picture.

🧠

Knows your whole week

Today is leg day. Tomorrow is rest. You're 35g under protein with 4 hours left. Kai weaves it all into every answer — "what's for dinner?" gets a real answer, not a list.

📈

Gets smarter the longer you use it

Three weeks in, Kai compares your real intake to your weight trend and proposes a target adjustment. No more "the formula says 2,200" while you stall at 1,900.

🏋️

Programming that adapts

Kai builds your weekly split from your training days, equipment and experience, then watches your logs. When a lift stalls it proposes a swap or a deload — and never changes your plan without a yes.

💬

Logging that doesn't feel like logging

"Had a Chipotle bowl, double chicken." Logged with the right macros. Just type it, or snap a photo of your plate. Your pantry and saved recipes remember what you actually eat.

📅

Weekly review & check-in

Every Sunday, a nudge for your weekly check-in: sessions done vs. planned, PRs, stalled lifts, what slipped, and one decision to make. The behavior-change loop other trackers don't have.

🔒

Remembers what you tell it

"I train MWF mornings." "Tweaky right knee." "Cutting for a wedding in July." Kai keeps these and uses them — without you ever repeating yourself.

How it works

The whole app is one conversation.

1 · 90-second onboarding

A short chat with Kai — goal, body stats, your training week. By the end you've got your starting calories and macros, and Kai knows what kind of week you actually train.

When do you train, and what?
MWF lifting, Sat is cardio.
Got it. Push/Pull/Legs + Saturday cardio. Starting you at 2,150 kcal · 180P · 220C · 75F.

2 · Every answer uses your whole day

Today is leg day. You had eggs and oats this morning. Kai knows both when you ask "what should I have for lunch?" — and gives a real answer, not a generic list.

what should I have for dinner?
It's leg day and you're at 1,820 kcal · 145P. Big bowl of rice + 8oz chicken + greens would put you right on target — bonus carbs for the morning lift.

3 · Adapts as your body responds

Three weeks of logged data beats a formula. Kai compares your real intake to your weight trend and proposes target adjustments — never silently changes them. You stay in control.

Last 3 weeks: you've stayed at 178 lb on ~2,100 kcal. Your real maintenance is closer to 2,100 than the formula's 2,300. Want me to bump your cut down by 200?
yeah do it
