PromptyGainz

Prompty Gainz is the voice-first AI fitness app that feels like texting your personal trainer.

Most fitness trackers make you stop, tap, scroll, and search just to log a meal or a set of bench press. Prompty Gainz removes that friction. Tell the AI coach what you ate or how you trained — by typing or speaking — and it handles the rest. Macros, training volume, calories, and trends are tracked automatically. Then the coach connects the dots between what you eat and how you train, and gives you advice that actually fits your life.

ONE COACH. ONE CONVERSATION. EVERYTHING TRACKED.

Type or say "I had 200g of chicken and a cup of rice" or "4 sets of 8 bench press at 185" and PromptyGainz logs it instantly with full nutrition or workout data. Ask "what should I eat to build my back?" and you'll get coaching grounded in your own training history — not generic tips from the internet.

WHAT YOU CAN DO

• Log nutrition by voice or text. The built-in macro tracker calculates calories, protein, carbs, and fat automatically, backed by the USDA Food Data Central database. Works as a meal tracker, calorie counter, and macro calculator in one.

• Track workouts. The workout logger captures sets, reps, weight, and total volume for every exercise. The exercise library learns from what you log — no fixed list to scroll through.

• Log cardio. Running, cycling, swimming, rowing, and more. Duration and calories captured in seconds. Doubles as your cardio tracker and fitness journal.

• Get personalized AI coaching. Ask any fitness or nutrition question. Your AI personal trainer uses your last 7 days of data to give advice that fits your training, your goals, and your habits.

• See your day at a glance. Macro rings, training volume, cardio summary, and a 90-day weight graph on the home dashboard.

• Browse your journal. Calendar view of every meal, workout, and cardio session. Tap a day to see the details.

• Read weekly reports. Macro averages, training volume by muscle group, consistency streaks, and AI-generated insights highlightingthe 2–3 most impactful changes you can make.

BUILT FOR PEOPLE WHO TRAIN

Prompty Gainz is built for people who train 3–5 times a week and care about both nutrition and training. Use it as your macro calculator, meal tracker, workout logger, cardio tracker, and AI fitness coach — all in one app. Simple by design — no cluttered tabs, no endless menus. The coach is the input. Every interaction takes seconds, not minutes.
