SummitMetrics doesn't log food itself. Log meals in MyFitnessPal — or Lose It!, Cronometer, or any food app that writes to Apple Health — and the Nutrition tab (part of Pro) measures them against your calorie and macro targets.
Nothing showing up? In the Health app, go to Sharing → Apps and check that your food app is allowed to write Nutrition and SummitMetrics is allowed to read it.
Subscription management — pause, cancel, restore — happens through Apple, not us. On iPhone: Settings → your Apple ID → Subscriptions → SummitMetrics. On Mac: App Store → your name → View Information → Subscriptions.
