Stacks: Eat, Lift & Progress

One app for the gym and the plate. Log your lifts, scan your food, track your macros and weight. Calm, fast, free.

Stacks brings calorie tracking and strength training together in one app. It opens on today: how your calories and macros stand against the targets you set, so you see where the day stands as soon as you open it.

Adding food is a few taps. Search the OpenFoodFacts database or look up a barcode, create your own foods when you need to, and save a meal you eat often as a recipe to add it again in one tap. If you miss a day, you can still add meals to past dates so the history stays accurate.

For training, build your own workout templates or start a session and add exercises as you go. Weight and reps are recorded with input modes for total load, per side, per dumbbell or bodyweight, with a rest timer between sets. Every session is kept in a full history, with personal records and per-exercise progress.

Body weight and measurements are recorded over time, with body weight shown as a 30-day trend. Each week, a review brings the period together: average calories per day, weight change, training volume and number of sessions. Daily targets are calculated from your sex, activity level and goal, whether you are cutting, maintaining or bulking, and optional reminders prompt you to weigh in, add the day's meals and check the weekly review. You can export your data at any time, or delete your account and all its data in one step.
