RistrettoFit

RistrettoFit works out the exact number of calories you should eat today, shows you what to eat to hit it, and gives you a fifteen-minute workout you can do in your living room. No gym, no equipment, no guessing.

Everything stays on your own computer. There is no account to create, nothing is uploaded, and it keeps working with the wifi off.

Highlights

1. A calorie target built from your body, not a chart - tell it your height, weight, age and how active you are, and it works out what you burn in a day and how much to eat to reach your goal by the date you picked.
2. It tells you when a goal is unsafe - ask to lose ten kilos in a month and it will say so, slow the plan to a pace that keeps your muscle, and never let the target drop below a level you can actually live on.
3. Three rings, one glance - calories in, calories burned and water for today, filling as you log. You always know how much room is left before you open the fridge.
4. A day of meals that actually adds up - breakfast, lunch, dinner and a snack, portioned to land on your calorie and protein numbers. Swap the whole day for a vegetarian or high-protein version in one click, or shuffle for something different.
5. Six real HIIT workouts with a proper interval timer - from a gentle four-move starter to classic Tabata and an all-out sprint ladder. Big countdown, the move you are on, the move that is next, a form cue for every exercise, and a beep so you never have to look.
6. Finish a session and the burn is already logged - scaled to your bodyweight. Stop early and it only counts the minutes you actually did.
7. A water tracker you tap, not type - the bottle fills as you drink, the target comes from your weight and how hard you train, and one tap undoes a mistake.
8. See the body you are working toward - a 3D figure built from your own height, weight and body fat, with a slider that morphs it from where you are now to where the plan ends. Drag it round, or stand the two side by side.
9. Weigh in and the whole plan moves with you - one number updates your calories, your macros, your water and the figure on screen.
10. Yours alone - no account, no sync, no analytics. Your weight and what you ate never leave the machine, and one button erases the lot.

How it works

Setup takes about a minute. Drag a few sliders for your height, weight, age and how much you move, pick whether you want to lose fat, hold steady or build muscle, choose a target and a date. Before you commit, it shows you the real number - your calories a day, your protein, your water, and a warning if the date you chose is asking too much.

After that the app opens on today. Log what you eat as you go, or take the suggested meals in one click. Start the workout it picked for you and it counts you through it. Fill the bottle. The rings close, the streak grows, and the figure on the Body screen slowly becomes the one you set out to build.

Perfect for

1. Anyone who has lost track of what they eat and wants one honest number to aim at
2. People training at home with no equipment and no idea what to do for twenty minutes
3. Anyone coming back after a long break who wants a pace that will not wreck them
4. People who would rather not hand their weight and their meals to an app that syncs to a server
5. Anyone who needs to see the finish line to keep going
