Common questions
- Where do the numbers come from? USDA FoodData Central, SR Legacy — about 6,900 foods, built in and available offline.
- What limits should I use? The ones your doctor or dietitian gave you. Renvi never suggests limits. If you don't know them yet, leave them empty and Renvi just counts.
- A food isn't in the list. Foods › Create — type the values from the label once.
- Restore a purchase. Settings › Restore purchases, or Restore on the Pro screen.
- Cancel a subscription. iPhone Settings › your name › Subscriptions › Renvi.
