Four areas sit in one circle: Health, Mind, Resources and Productivity. Each has its own colour. Tap one and it opens into its parts. In Health, you see what you ate against what you burned, and what that means for fat and muscle.

4dAi learns what you usually eat at each meal, on each day of the week, and what exercise and sleep are usual for you. It predicts your day from that. Check it, change an amount or a time, take a dish off, and log the whole day in one tap. The more days you log, the better it gets.

Food logging made for Indian vegetarian food. Use your mess menu, or make a menu for your own week. You get a balanced plate for each meal.

Protein, carbs, fat and fibre for every food. The app also checks 12 vitamins and 11 minerals against the ICMR-NIN 2020 targets. So you can see what your food is missing.

One table shows every food’s calories, protein, carbs, fat, fibre, vitamins and minerals. Another shows every exercise’s calories at your weight. Find them under Health › Food › Food figures. Change any figure for a profile, and the whole app uses your figure. Add your own foods and exercises, each with a picture. You can go back to the app’s own figures at any time, for one or for all. On a phone, you set each figure with two wheels, without the keyboard. Your figures are saved with your account.

Calories for lifting, holds and conditioning. The app works them out from the movement, your height and your weight.

Make a list of the exercises you really do, like resistance bands at home or your usual machines at the gym. Exercised then shows this list first, as pictures. Tap the ones you did today. Then enter the reps and the weight or band for each.

See how each muscle is recovering, based on your training, sleep and food. For each sport you play, see how many minutes are left this week and how hard to go today. Each week stays at about 10% more than the last, to help you avoid injury.

Answer a few questions: what you want most (lose fat, build muscle, both at once, eat healthy or get fitter), how many days a week you can train, at a gym or at home, and any foods you do not eat. 4dAi then makes a plan: the day’s calories, protein, carbs, fat and fibre, a balanced plate, the vitamins and minerals to watch, what to keep out, and a training week. Your day, predicted then shows how much of each food fits your goal.

Choose your goal: build muscle while losing fat, keep muscle while losing fat, or bulk (gain weight to build muscle). The plan sets your calories, protein, fat and carbs for the day. It gives you a training week for the gym or for home: full body, upper / lower, or push, pull, legs + core. You log today’s workout in one tap, and it gets harder by no more than about 10% a week. The plan also makes today’s plates from your mess menu or your own, sized to the plan. Every figure links to the research behind it.

Draw your day as slices on a circle: study, gym, meals, work. See it as two circles (your sleep and your day), as one 24-hour clock, or as two 12-hour clocks like a wall clock. Tap a slice to fine-tune it to the minute, just under the clock. Say your plan, and it is drawn for you. Copy a day’s plan to other days, or repeat it each week. Each slice becomes a task, with a reminder when it starts.

Each week of your life is one square (on a phone, each month). The phases of your life are coloured in. Show your whole life, or only the years ahead. Plan the week ahead. On Sunday night, look back on what happened and what you learned. The app reminds you to do both. With sync, it is encrypted with your passphrase.

See where your rupees go, item by item. Type a spend in, or tell the AI agent (“groceries 450”, “auto 60”). Or switch on payments by themselves, and your bank’s alerts are logged as they come. See each day’s spending. See where it went over a week or a month: by category, day by day, against the days before, your biggest spends, each weekday, and where the month is heading. Download it all as a spreadsheet. You can track the hours you spend on things the same way, under Time spent in Time management.

Charts of your training and your month. Every method says where it comes from, with links to the research.

Tell the app what you studied today, and it reminds you to recall it. It reminds you the next day, on day 3, after a week, and then at longer and longer gaps. Each reminder says how to recall it, and why.

Each morning and night, pick a few words for how you feel. The app draws them over the weeks. When hard feelings keep coming back, it tells you. It also finds help near you, by your phone’s location or a city’s name: psychiatrists, psychologists and counsellors, mental health hospitals and clinics, and health and wellness centres (Ayushman Arogya Mandir), each with its phone number and address. Free helplines are there too.

Make as many profiles as you need. One account can follow every member of the family. Each person has their own food, training and recovery. If they like, each can also have their own passphrase to open their profile.

If you want, keep the same data on your phone and your computer. It is locked with a passphrase that only you know.
