About this app

LunaFit is the first truly adaptive AI personal trainer built to plan your workouts, track your meals, and adjust your program automatically. Speak to your coach in natural language using your own voice. You talk, and your coach listens, responds, and guides you in real time. No typing, no spreadsheets, no guesswork. Just tell your coach about your workout, meal, hydration, steps and sleep and LunaFit logs everything for you.

Whether you're a beginner, trying to lose weight, or rebuilding consistency, LunaFit learns your patterns, understands how you’re feeling, and updates your plan in real time. It feels like a coach that actually cares. One that listens, responds, and evolves with you every day.

With the power of voice logging, speech recognition, and natural language understanding, you can effortlessly track your meals, workouts, sleep, hydration, and steps. Connect a wearable through Health Connect and LunaFit logs your data automatically.

This isn’t another tracker. LunaFit is an adaptive health intelligence system that thinks ahead for you.

Ratings and reviews

I want to love this app, but didn't realize until my plan was set that it wasn't right for my needs. Tried to have the AI revise the plan or start over, but was told that wasn't possible. She did try to revise the first week, but the incorrectly scheduled items wouldn't disappear, and the activities I wanted to schedule were automatically entered as already logged. We also talked in circles a few times. Has a few glitches & design flaws that need to be fixed, but potential to be a great app.

this app is almost there. i still have it installed because its a cool looking app. but i hardly use it. will the devs be adding in a AI food calorie nutrition cam scan? right now it only scans barcode. when i cook at home i dont cook by barcodes. unless i have a protien bar 🫪. anyway its a cool app almost there for a complete all in one app. oh the social feed is dumb. there is nothing social about it.

I love this all in one wellness companion and very easy to use and understand! Everything is tracked automatically for me, watch activities, heart rate, nutrition, sleep and more. I can also see the right way of doing an exercise while on a workout(a library with every possible exercise there is out there)
