Track precisely when you can. Estimate honestly when you can’t.

Scan a barcode or nutrition label, search the food database, or estimate from a photo or description.

This day combines database foods with photo estimates. The result is ~2,695 calories, likely 2,540–2,845, against a 2,700-calorie goal.

Ballpark showing an estimated 2,695 calories, likely 2,540 to 2,845, against a 2,700-calorie goal, with the verdict Likely on track — Exact entries stay exact. Estimates keep their likely range.

A shared meal

A camera can’t see how much was yours.

Ballpark estimates everything on the table, then lets you adjust how much you actually ate. The components, macros, and likely range move together.

Ballpark showing an estimated 1,970 calories for the full meal on the table — **On the table:** ~1,970 calories.

The same meal after setting amount eaten to one half, showing 985 calories — **What you ate:** ~985, after one slider.

How it works

Simple when the meal is simple. Honest when it isn’t.

Start with a barcode scan, a nutrition label, a database food, a photo, a screenshot, or a description. Exact entries stay exact. When an answer would meaningfully change an estimate, Ballpark asks.

Capturing a meal photo with an optional note — Photo and a note, if you have one.

Ballpark asking a clarifying question with both candidate ranges shown — It shows what each answer would do before you pick.

Editable component list with a proportional amount eaten control — Every component editable, with amount eaten.

Weight progress

Sometimes the honest answer is “not yet.”

Fifteen weigh-ins across thirty-four days can still overlap with ordinary daily variation. Ballpark shows the range the data supports and leaves the center dashed until the direction becomes clear.

Losing Screenshot placeholder

A resolved downward trend.

A resolved upward trend.

Where AI helps

AI handles the tedious part. You keep the judgment.

Ballpark uses AI to read photos and descriptions, identify uncertainty, and prepare an editable estimate. It keeps the inputs, assumptions, and likely range visible. You decide what to do with them.
