Daylum for iOS and Android
Build a journaling habit
Daylum tracks one habit: journaling. Goals give it a rhythm, streaks measure the run, reminders keep it prompted, and the record it builds stays on your phone.
Scope
The one habit Daylum tracks
Daylum is not a general-purpose habit tracker. There is no list of habits to tick off, and you cannot add drinking water or going to the gym as a box to check each day.
The habit it tracks is journaling. In the app, a goal is a journaling habit you repeat each day, week, or month, and progress fills in as you log. If the habit you want to build is a written one, showing up on the page once a day or a few times a week, that is exactly what the goal tracker measures.
Keeping count
A rhythm, and an unbroken run
Stats
A goal gives the habit its rhythm: journal every day, three times a week, or ten times a month, with the count starting over when the window turns. Streaks measure the run itself: consecutive days with at least one entry, shown as your current run and your best ever. If your last entry was yesterday, the streak is still alive today; a day fully missed is what breaks it.

Prompting
Reminders that stay on your phone
Daylum can prompt the habit two ways. The Reminders manager in Settings schedules journaling reminders, each with its own time and its own weekdays. And any goal can carry its own reminder, repeating on the goal cadence: daily, weekly when the week starts, or monthly on the first.
Reminders are free, with no cap on how many you keep. They are local notifications, scheduled on this device: Daylum asks for notification permission once, when you turn a reminder on, and no reminder data ever leaves your device.
Looking back
What the habit gives back
A kept habit turns into a record you can read. The calendar colors each day by its mood, Year in Pixels lays the year out one pixel per day, and the statistics screens read trends and patterns out of whatever the habit has written down.
All of it stays where the habit happened: your journal lives in app-private storage on your device, with no account and no upload.
