Most wellness apps give you fourteen metrics and no idea what any of them mean. Horizon gives you one number. Photograph a meal and it works out the calories and macros. If it's wrong, say so in plain language and it re-estimates. Habits, workouts and food fold into one daily score, with a plain read of how the day went. Workouts sync from Apple Health and Health Connect. No streaks. No badges. No confetti. Twice a day, not every hour. The maximum score is 99. There is no 100.
I built Horizon because every tracking app I tried either buried the answer under a dashboard or turned it into a game I stopped caring about.
The idea is narrow: one score, twice a day, and a plain read of how it went. Photograph your food, tick your habits, let your watch handle workouts. If the estimate is wrong you correct it in a sentence rather than doing the arithmetic yourself.
Some of it is deliberately unfashionable. No streak pressure, no celebration animations, greyscale throughout. And the score caps at 99, because nobody has a perfect day.
Happy to answer anything about how it works or why it's built this way.
