About this app

PREP is a meal prep app for people who cook their food in batches.

Set your calories and macros once. From there PREP plans the week, splits a cooked batch into portions that match your targets, and logs the whole thing in one go.

A meal planner, calorie counter and macro tracker in one app, for losing weight, gaining, or holding steady.

PLAN THE WEEK

Log a whole week at once instead of opening each day one by one. Pick the days you are prepping for, add the foods or recipes, tap log.

Eat the same breakfast five days running and that is one entry instead of five.

PORTIONS

Cook a batch, weigh it, enter the weight. Your targets are already set, so PREP works out the grams that go in each container straight away.

Sides such as rice or potatoes can be added, and the split rebalances around them. If the cooked weight is not exact, set a reserve and PREP holds a little back, so every portion stays accurate instead of the last one coming up short.

Smart split handles two people. When two profiles eat from the same batch on different targets, PREP divides it proportionally so both land as close to their own numbers as the food allows, rather than one eating well and the other going short. It tells you when it cannot reach both targets exactly, instead of quietly rounding.

Once the split looks right, log it for the whole week in one tap.

RECIPES

Build recipes from your own ingredients. Enter the weights once and PREP calculates calories and macros for the full dish, per 100g, and for any portion of it. Send a recipe straight into the portion tool when it is time to cook.

FOODS AND TRACKING

A curated food library to search, plus your own. Add a custom food once and reuse it, sort things into your own categories, scan a barcode when you need something new.

Your day is grouped by meal, with calories, protein, carbs and fat against the targets you set. Targets are saved against the day they were set, so changing a goal later leaves earlier days as they were.

PROGRESS

Weight and measurements shown as a trend line drawn over the daily readings, so one heavy morning does not look like a setback. Nutrition charts across weeks.

GOOD TO KNOW

PREP is built around food you cook yourself, so it works best once you have added your own foods and recipes. The food library is curated rather than enormous, there is no photo recognition, and no browsable collection of ready made recipes.

It also stays deliberately narrow. No step counter, water tracker or workout log, and nothing social. The aim is to do meal prep and tracking properly rather than a bit of everything.

No ads, no public profiles, nothing sold to anyone. An internet connection is required.

SUBSCRIPTION

Install PREP and open it without entering payment details. Creating an account starts 14 days of full access, free, and nothing is charged when the trial ends.

After that PREP continues as a monthly auto renewing subscription, charged to your Google Play account at confirmation of purchase. It renews unless cancelled at least 24 hours before the end of the current period. Manage or cancel any time in your Google Play account settings. The price is shown in Google Play before purchase.
