Health Horizons
The energy-balance judgment on top of Apple Health, in your own logger's numbers.

Coming SoonProduct2026–present
The Today screen on iPhone: three nested arcs for intake, burn and balance with the calories left for the day in the middle, a line naming the app each number came from, and tiles for eaten, budget, active energy, steps, exercise and weight.
Today. Every number in these screenshots is the app's built-in sample data, not anyone's Health data, and the app names on the sources line are invented.
The Horizons screen set to Week: a Day, Week, Month, Year and Forever picker, the date range for the last seven days, the same three-arc gauge drawn over the week's totals, and tiles for average intake, average expenditure, net against budget, on-target days, weight trend change and expected change.
Horizons, one week. The same gauge as Today, over the whole window.
The Weigh-ins screen: a weight field noting it is the only thing the app writes to Apple Health, a ninety-day chart of readings over the smoothed trend with a dashed goal line, and a month's list of weigh-ins with the app that wrote each; one scale reading is struck through and marked Removed.
Weigh-ins. A reading you don't trust comes out of the trend without being deleted from Health.
The iPhone Home Screen widget gallery filtered to Health Horizons, showing the small Today widget with the three-arc gauge and calories left, and an Add Widget button.

Settings, Apple Health page: the app icon and name, the line 'Reads what you eat, burn and weigh. Writes only your weigh-ins.', and switches for Intake, Energy burn, Steps and exercise, and Weight, each with a sentence on what turning it off does.
Settings ▸ Apple Health. Switches for what the app uses; Health still decides what it may see.

Health Horizons reads what you eat, what you burn and what you weigh from Apple Health, and it never asks you to log a meal. Keep the calorie logger you already use. Health Horizons reads its numbers out of Health and names the app each one came from, so you can always see who wrote what. The only thing it writes back to Health is the weigh-in you type.

Plenty of apps count calories. What this one adds is the judgment on top of the counting. It estimates your resting metabolism, turns that into a daily expenditure from the energy Health measured, and sets a budget from the goal you choose: lose, maintain or gain. Once a week it checks that estimate against your weight trend and calibrates, so the budget follows what your body is doing rather than what a formula assumed.

The answer is one gauge. Three arcs — intake, burn and balance — show where the day stands, and the same gauge draws the week, the month, the year and forever over that window's totals, with the number in the middle saying how much the whole window has left. A week can mean the last seven days or the week you are in, so the date label is a switch between rolling and calendar periods.

Weigh-ins get their own tab: every reading, the smoothed trend under it, and the app that wrote each one. When a scale records a reading that isn't yours, Remove takes it out of your trend and every horizon. Health only lets an app delete what it wrote itself, so a weight you typed here is deleted, and a scale's reading stays in Health with the row saying so.

Apple Health is the record. No health data goes to iCloud; Apple already syncs Health between your devices end to end, and the app's cached ledger stays on the device.

It is built iPhone first. The iPad, Apple Watch and Mac apps and the widgets live in the same codebase. Health Horizons is not on the App Store yet; the newsletter is where it will be announced.
