An AI diet, training, and sleep app that actually adjusts when your body changes.
Your body shifts every few weeks. Hunger, energy, sleep, weight, recovery. Most apps keep showing you the same plan. ren doesn't.
Plenty of apps will track your numbers. Almost none of them change the plan when the numbers do.
Every app uses AI now. What matters is what the app does after it sees your week. ren responds. Static apps don't.
Every week, ren asks you five short questions. Combined with your weight trend and sleep score, the answers tell ren whether your plan still fits. If it doesn't, ren changes it.
Are you fighting your hunger this week, or working with it?
Is the deficit costing you Tuesday afternoons, or holding up?
Flat, or still yourself?
Spiking late at night, or quiet enough to ignore?
Sessions feeling sharp, or dragging through the warmup?
Diet Fatigue, Pace Too Slow, Losing Too Fast. Whichever one fits this week, your calorie and macro targets shift to match.
None of these features sit alone. They feed each other. That's what lets the plan actually adapt.
Snap your meal. ren estimates calories and macros. You review, edit, log. No more searching a database for "medium chicken thigh."
Your hand is already calibrated. Palm of protein, fist of veg, thumb of fat, cup of carbs. ren teaches the system and tracks against it. No food scale required.
Meals matched to your macros, allergies, and preferences. Grocery list assembled from the plan, ready when you are.
Point your camera at a nutrition label. ren reads it, logs it, files it in your saved foods.
Scores your night, and feeds the score into your weekly nutrition check-in. A bad sleep week can be why your fat loss stalled. ren knows that.
Full-body, upper/lower, push-pull-legs, body-part splits. ren auto-picks the right one for your goal and schedule, then builds it.
After working sets: joint pain, soreness recovery, pump, volume. The plan adjusts based on real input. Not after the program. During it.
Weight trend, body composition, measurements, progress photos. Connected to the rest of the system, not a standalone tracker.
Recipes with macros, grocery integration, reactions, and personal notes. Real food, real people, real macros.
Your plan was right. For week one. Then your body changed and the plan didn't.
Maintenance calories drift down 50 to 150 a week into a cut. ren sees the drift. Static apps don't.
Hard week of training, light week of sleep. The nutrition plan should know about both. ren does.
Body comp moves slowly. The data needs to land somewhere that listens to the whole picture, not one number on a scale.
Under 6 hours? You can't out-train or out-eat that deficit. ren tells you when sleep is the bottleneck.
ren is built for exactly this. One app for diet, training, and sleep, and the three actually feed each other. Your sleep score affects your weekly nutrition check-in. Your workout feedback adjusts your training plan. The pieces talk to each other, which is the whole point.
Yes. That's ren's core feature. The weekly 5-question check-in (hunger, energy, mood, cravings, workouts) combined with your weight trend and sleep score diagnoses what's happening (Diet Fatigue, Pace Too Slow, Losing Too Fast) and adjusts your calorie and macro targets.
Yes. Photograph your meal and ren estimates calories and macros. You review and edit before logging, so you stay in control. ren also includes nutrition label OCR for packaged foods.
Yes. ren's AI plan builder generates programs based on your goals, equipment, experience, and schedule. It supports full-body, upper/lower, push-pull-legs, and body-part splits, and can auto-pick the right one. Per-set feedback (pain, soreness, pump, volume) adjusts the plan over time.
The sleep journal scores each night and feeds that score into your weekly nutrition check-in. A bad sleep week can be why your fat loss stalled, and ren actually surfaces that connection. Most apps treat sleep as a silo.

No. ren is for general wellness: nutrition, training, and sleep guidance. It's not medical advice. If you have a clinical eating disorder, a metabolic condition, or anything else that needs a professional, see one. ren is honest about its lane.
Diet, training, and sleep. One app, one plan, listening to you week by week.
