What is Stadig?
Stadig is two free apps for training and nutrition on iPhone, iPad, Mac, Apple Vision Pro and Apple Watch: Stadig Lift and Stadig Macro. They share one idea: use your own data to prescribe the next thing to do, instead of charting what you did. The name is Norwegian for steady.
What does it cost?
Nothing. Both apps are free, all of it: every plan, every target, every way to log. There's nothing to unlock, no ads and no account.
Do I need both apps?
No. Each app works alone. Together they share a profile, life modes and a calendar, so Stadig Macro's phase shapes Stadig Lift's block and Stadig Lift's step count is read before Stadig Macro cuts calories. With both set up, each app shows all six scores.
What are the six scores?
Strength, Physique, Endurance, Agility, Vitality and Discipline, each from 0 to 100 and drawn together as your shape. Stadig Lift measures Strength, Physique, Endurance and Agility; Stadig Macro measures Vitality; Discipline is shared, the plan kept in the gym and at the table. Each app shows its own scores, and with both set up each shows all six, labelled with the app that measures it.
Do the apps work offline?
Yes. The exercise library and the food and supplement catalogs ship inside the apps. Sync between your own devices uses iCloud when you're online.
Where does my data go?
Your devices and your private iCloud database. There is no account and no analytics. Stadig Macro's photo and label reading uses Apple's on-device model, and Apple's Private Cloud Compute only when you turn that on.
What does "prescribe, don't describe" mean?
A tracker describes: here is your volume, here is your calorie average. Stadig apps prescribe: add 2.5 kg to the next set, eat 150 kcal less this week. Every screen ends in an action.
Why no streaks?
Streaks reward showing up, not improving, and they punish the rest days a good plan contains. Discipline in Stadig apps is a four-week adherence rate with a target band, where one missed day barely registers and vacations and illness don't count at all.
What devices are supported?
Both run on iPhone, iPad, Mac and Apple Vision Pro, and both have Apple Watch apps. On the iPad and the Mac each does more than on the phone: Stadig Lift lays out your program and exercise library, and Stadig Macro compares foods and plans the week. Your data syncs between your devices through iCloud.
Which AI models do the apps use?
Only Apple's. Stadig Macro uses the on-device Foundation Model to name foods and amounts from a photo, a sentence or a label scan. The nutrients always come from the offline catalog. No third-party AI service ever sees your data.
How do I pronounce Stadig?
STAH-dig. It is the Norwegian word for steady.
