Loendur

Read full description

Loendur is a counter app for anything worth keeping track of - and it keeps the story behind the number, not just the number. Habits, routines, health, work, hobbies: one tap counts, and the entry remembers when it happened, where you were, and what it looked like. What Makes Loendur Different Built local-first, so every tap is instant and everything works offline. What you count stays on your iPhone. No accounts. No ads. No cloud. Capture More Than Just Numbers • Photo attachments - add an image to remember exactly what you counted • GPS location - place the pin on a map and see where it happened • Notes and timestamps - context on every entry • Extra fields - a second number for weight, distance or duration, or a simple yes / no Flexible Display Modes - each counter shows the number you actually care about: • Today, This week, This month, This year • All-time total • Days since last entry • Current streak • Daily remaining - counts down from a daily target Look Back Through Time Step a counter back a day, a week, a month or a year. The big number, the statistics and the history all move with you, so last month reads exactly like this one. A Year at a Glance See a counter's whole year as twelve month blocks. Every day with entries carries a coloured chip, and the deeper the colour the more that day counted. Swipe sideways to move between years. Statistics You Choose Every counter carries its own set of stat tiles - totals, averages, streaks, best week, best month, and rolling windows for the last 7, 30 or 90 days. Pick the ones that suit it, put them in the order you want, and see each tile's current figure while you choose. Each tile says what window it measures. Smart Organization • Home Screen widgets in all three sizes - count without opening the app • Each widget can show the period you want - today, this week, this month, this year, or the last 7, 30 or 90 days • Lock Screen widgets - progress at a glance • Archive - retire a counter without losing a single entry • Recently Deleted - bring back a counter deleted by accident • Search - find any counter as you type • Hidden counters - a private list behind a six-digit code you choose (one-off purchase) Light or Dark Follow the system, or keep Loendur light or dark whatever the phone is doing. Colours That Are Yours Give a counter any colour you like, or take one of the suggestions. Its colour follows it everywhere - list, history, widget. Your Data, Your Way Export one counter or everything as CSV or JSON, any time, with no account and no waiting. Import to migrate from another app or restore a backup. Built for Speed Loendur is built for instant, effortless capture. No loading. No waiting. Just count. Perfect For • Hobbies and projects (photos taken, plants watered, meals cooked) • Work (deliveries, calls, shifts) • Health (water, medication, symptoms) • Habits and routines (meditation, reading, chores) • Fitness (workouts, steps, reps) • Anything you want to count Privacy First • Works fully offline - no internet required • What you count never leaves your device • No accounts or sign-ups • No ads • Anonymous usage analytics stay off unless you turn them on, and never include what you count Whether you are building a habit, tracking your health, measuring your work or just curious about your own patterns, Loendur adapts to you and stays out of the way.
