About

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, and with Stacks Pro lay those templates out over a week, rest days and all. 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. Stacks Pro is an optional subscription. It unlocks unlimited meal photo and receipt scans, training programs that lay your workout templates out over a week, rest days included, and a suggested weight and rep count for your next set, based on your own training history; every other feature works without it. It comes as a monthly or an annual plan, with a free trial for new subscribers, and renews automatically unless it is cancelled at least 24 hours before the end of the period. The price for your region is shown in the app before any purchase, and payment is charged to your Apple account. Terms: https://usestacks.app/terms

What's New in Stacks

1.7.0

October 26, 2026

A new look, and more of your week in one place. The whole app has been redrawn, with a new icon: calmer screens, each with one number to read first. Meals sit on a timeline through the day, and each meal opens on its own summary. Training goes beyond lifting. Running, hiking, cycling and other activities are logged from the plus, and show up in the week and in your history. With Stacks Pro, a program schedules them alongside lifting and rest days. Finishing a workout now opens a recap of the session. History and statistics share a single screen, each template shows its own progress and the muscles it works, and the rest timer counts down on the Lock Screen and in the Dynamic Island. A meal can be described in a sentence, spoken or typed, and comes back as a list of foods to review before it is added. Like photo scans, it is part of Stacks Pro, with a weekly allowance on the free plan. Body weight reads more clearly: a dated chart you can scrub with a finger, and a goal weight that shows where the trend is heading. Also in this version: • Home Screen and Lock Screen widgets for today, the streak, consistency, the training week and volume, with an optional weekly workout target • Share cards in three styles: solid, over your own photo, or as a transparent sticker • A food created by hand after a barcode scan stays linked to that barcode • A cutting target no longer drops below your basal metabolic rate or a safe minimum • Sets are logged without waiting for the network, and the keyboard moves from one field to the next • The day follows your device's time zone, reminders and streak included • Streak milestones, records and finished workouts are marked by a brief animation
