One conversation.
Your entire fitness life.
One agent doing the job of five apps: it logs your meals, builds your workouts, sets your macros, tracks your trends, and answers the questions you'd normally ask ChatGPT. And because it's one brain, every piece knows about the others.

A meal, a glass of water, a workout, and a weigh-in, logged from a single sentence. No forms, no database search, no switching apps. Twenty seconds, done.
Most people fall off because tracking takes too much effort: the menus, the database searches, the dozen taps just to log a sandwich. Fitly skips all of it. Just say what you had, by text or voice, and it's logged. You can still scan a label, snap a photo, or type it by hand. But you never have to.
Imagine having someone who remembers every meal you've eaten, every workout you've done, and every goal you've set. That's what Fitly does.
The modern fitness setup is a part-time job: one app for food, another for lifting, a calculator for macros, a spreadsheet for weigh-ins, and a browser tab for every question in between. None of them talk to each other, so you're the one carrying numbers across apps and making the calls. Fitly replaces the stack, and the job of managing it.

Fitly AI · $24.99/mo
One agent. One brain. All of it.
$45-60 a month across the stack, and you're still the integration layer. Fitly AI is $24.99, and the pieces finally share a brain.
Most apps bolt a chat box onto a database. Fitly is different: the chat isn't the product, it's the remote control. Behind it is an agent with 50+ tools that logs your meals, edits your plans, recalculates your targets, and remembers what changed. You don't operate software. You talk to your agent, and it does the work.
Describe what you ate in plain English, or just say it out loud. "Chicken burrito bowl from Chipotle with extra guac." Done. Macros logged.
Take a photo of your plate, a nutrition label, your scale, even the treadmill screen. One snap. Fully logged.
You told it your goals. It built your entire program, workouts, meals, everything, around your injuries, allergies, and preferences.
Separate apps keep separate notes. Your agent holds everything in one head, and the longer you use it, the sharper it gets. Every answer is built on your data, not generic rules.
You mention a sore knee in passing.
Tonight's leg day rebuilds around it.
You log a brutal workout.
Dinner advice accounts for what you burned.
You say you hate cilantro. Once.
No meal plan ever includes it again.
Your weigh-in trend stalls.
Your agent spots it and suggests new targets.
Your food app doesn't know you trained today. Your workout app doesn't know you're cutting. Fitly knows both, because there's only one of it.

Some days you want to talk. Some days you just want to tap. Fitly pairs the chat with full Meals, Workouts, and Progress tabs, real manual tools, timers, a barcode scanner. Log a set in the workout tab, or just tell your agent you did it. Either way it lands in the same place, instantly in sync.
No more giving up because a food isn't in the database. Fitly works through four layers to find your macros, and if they genuinely can't be found, it estimates them. And if it's ever unsure about a portion, it asks instead of guessing. You're never stuck staring at a missing entry.
A clean, curated nutrition database, not junk crowd-sourced entries.
Millions of packaged products via the Open Food Facts database.
Restaurant meals and obscure foods, pulled fresh from the web.
Still nothing? Your agent estimates the macros so you keep moving.
Browse a library of ready-made workout and meal plans, training splits, goal-based programs, lifestyle and specialty plans, even themed ones, and activate one in a tap. Not sure what works for you yet? That's the point: try a push/pull/legs split this week, a full-body plan next, swap your meal plan whenever, and keep the one that actually clicks. Or just tell your agent your goal and it builds a plan around your injuries, equipment, and the food you actually eat. Then tweak anything.

Light, dark, seasonal, neon. Make the whole app feel like yours: 21 out of the box, and 17 more to unlock from mystery boxes as you go.

Name your agent, then shape how it thinks and how it sounds, separately. Choose an approach for what it notices and pushes on, and a voice for how it talks to you. The longer you use it, the more it feels like talking to someone who actually knows you.
Supportive meets you where you are. Scientist guides from your numbers and trends.
Warm, Direct, Measured, or Hype. Same brain, different tone and energy.
The pizza. The skipped workout. The week you went quiet. Tell Fitly the truth and it meets you with a plan, never a lecture. No shame, no sighs, no "you should know better." Just the next small step, at 2am or after a month off, every time you come back.
Fitly isn't built by a team that read about weight loss. It's built by two people who lost 230 lbs between them and kept it off.

Lost 80 lbs. 25+ years building products. 4 software patents. Former CTO. Built Fitly to be the app he wished existed during his own transformation.

Sometimes I feel like it knows what I'm saying before I say it.

I logged a meal from a restaurant... just listed the items on my plate with rough estimates, and it logged it fairly easily!

Fitly speaks MCP, so Claude, ChatGPT, or any AI agent can read and update your fitness data without opening the app. Available on Pro.
Software you operate keeps records. An agent gets things done. Here's what an ordinary week looks like when your fitness runs through one:
That's the difference between software you operate and an agent that works for you. It's also why Fitly costs more than a database with a search box.
