Halftide

Some days you have twelve units of energy. Some days you have four. Halftide is a pacing app: a place to see which kind of day it is before you spend it. Pacing means staying inside the energy you actually have, instead of paying for a good day three days later. Halftide does this without a wearable and without a heart rate reading. You tell it what the day cost, and it keeps the ledger. It is a journal, not a coach. Going over budget produces a note, never a verdict. IN SHORT • Free. Every feature. No subscription, no in-app purchase, no trial. • No wearable, no heart rate, no HRV. Entry is manual and takes under a minute. • No account, no server, no network requests of any kind. • Does not read from or write to Apple Health. WHAT PACING LOOKS LIKE HERE Find a sustainable baseline. You set one once. After about two weeks, if your own records point somewhere else, Halftide says so — and suggests, never overwrites. Before you have any history it tells you plainly that it has none, and uses a general shape instead of pretending. Count the cost of everything, not only steps. Twenty-three kinds of cost across four domains — body, mind, feeling, senses. A hard decision costs something. So does holding it together in front of people. Energy does not only leave through your legs. Watch for the delayed price. When you flag a warning sign, Halftide looks back across the previous three days, because the price of Tuesday often arrives on Thursday. Plan the day before it starts. A morning number, a short line of plain language about where it came from, and a plan you can put activities into and see the total before you commit. Rest on purpose. A soundscape for lying down — four ambiences, three quiet themes, and a timer that keeps running when the screen locks. ALSO IN THE APP • A calendar of your months, with moon phases and short notes on any day. • Two prediction paths. If your energy runs on a cycle, it uses the cycle. If it does not, it uses your recent averages, your day-of-week shape, and the load you are still carrying. Neither is an afterthought. • Six companions. One sits with you and shows how the day is going. They grow from rest, not from streaks. • Widgets and Dynamic Island, so you can check without opening anything. • English and Simplified Chinese, following the device language. PRIVACY No account. No server. No network requests at all. Everything stays on your device, and there is nothing for anyone to collect. NOT THIS No streaks. No badges. No push notifications telling you to do better. No step goals and no rings to close. Nothing to buy. Halftide is free, and version 1.0 has every feature in it. Halftide is a self-reported energy journal, not medical advice.
