Ballpark on your wrist. Requires the free Ballpark app for iPhone, version 1.1 or later. Ballpark is a weight tracker that filters the day-to-day noise out of the scale, and a food log that asks you to guess rather than pretend you measured. This watch app is the quickest way to feed it: the entries you make here land in the iPhone app, which does all the arithmetic. ON THE WATCH • Meals — the meal that is due, or any of today's: Small, Medium, Large, Huge, or None if you skipped it. It opens on Medium, so the commonest entry is two presses. • Snacks — Small, Medium, Large or Extra large. Every press counts. • +100 — add a flat hundred calories for anything in between. • Weigh in — starts at your last reading; step up or down to the number on the scale and press START. • Today at a glance — a calorie ring, a dot for each meal, what is left of your target, your trend weight with a three-week line, and what is due next. NOTHING GETS LOST Every entry stays on the watch until the phone confirms it, and the watch shows how many are still waiting. A breakfast logged out of range is filed under the day you ate it, and an entry you have since corrected on the phone is not overwritten by a late delivery. SETTING UP 1. Install Ballpark on your iPhone (1.1 or later). 2. In Ballpark, open Settings › Garmin watch › Connect a Garmin watch, and pick this watch in Garmin Connect. 3. Open Ballpark on the watch. The watch talks only to Ballpark on your own phone. No account, no analytics, nothing sent anywhere else. Calories per portion are shown on the watch only if you switch them on in the iPhone app. The watch app is in English. Nothing here is medical advice.
