iPhone
Snap your food and see if it fuels your workout. PreMax scores any meal S to F for your training, with an energy, strength, and crash forecast timed to your window.
PreMax answers one question: is this food a good pre-workout?
Point your camera at a meal or a snack and PreMax grades it from S down to F as
fuel for your training. No logging, no calorie math, no guesswork. You get a clear
letter score, a confident verdict, and a full forecast of how that food is likely
to carry your session.
HOW IT WORKS
Snap a photo of your food. PreMax recognizes it, pulls its nutrition, and scores
it for the workout you are about to do. The same plate is not graded the same for
every session: leg day and cardio reward carbs, push and pull lean on caffeine and
forgive a little fat, and HIIT punishes a heavy, fibrous stomach. PreMax accounts
for all of it.
YOUR SESSION FORECAST
Every score comes with a breakdown you can actually use:
- Energy, strength, endurance, pump, and focus, projected for your workout.
- A crash-risk meter so you know if that food is going to drop you mid-session.
- Your best fuel window: how many minutes from now this food is working for you.
- The muscles you are training today.
SCORE FOR ANY WORKOUT
Switch between legs, push, pull, chest, back, full body, HIIT, and cardio and watch
the same food get re-scored instantly. See why a banana is elite before legs and
why a heavy, greasy plate is a skip before sprints.
TIMED TO YOUR WINDOW
Tell PreMax when you usually eat before training, from right before to ninety
minutes out, and the forecast is built around that window. Fuel that is perfect at
fifteen minutes is not the same as fuel for ninety minutes out, and PreMax knows
the difference.
PRIVATE BY DESIGN
There is no account to create and no email to hand over. Your scan history and your
preferences stay on your device. Your food photo is used only to recognize the food
and is not stored on our servers.
BUILT FOR ANYBODY
Whether you are chasing a PR, grinding a cut, or just trying to stop feeling flat in
the gym, PreMax turns "should I eat this before I train" into a one-second answer.
Snap it. See the score. Train better.
