Food quality
A clear view of what you’re eating.
The Food Quality bar sits under your calories. It fills based on nutrient density, weighted by calories. Leafy greens score high. Alcohol scores zero. Chocolate sits somewhere in between. Stay under your calorie limit and watch the bar rise as you choose better foods.
Logging
Add food without friction.
Search the local database or pick from Recent, Favorites, or Common. Tap a portion button and the entry is logged. The calorie total and Food Quality bar update immediately. No confirmation screens. No delays.
Database
Accurate data, instantly available.
OnForm includes the entire USDA FoodData Central food database, stored on-device. This means search happens instantly on your phone - not on a slow online database. Updates arrive in the background when you’re connected, the same way map data updates on a phone.

How the numbers were calculated
On-device figure comes from typical SQLite query times for indexed text search on mobile (local disk/memory, no network).
Online figure comes from published API response-time data and mobile network latency measurements (cellular round-trips commonly land in the 200–600 ms range for a complete request).
In practice the gap feels even larger because online searches also introduce variable delay and failure states when the connection is weak. Food data from USDA FoodData Central.
