Built for speed and clarity
One swipe logs an entry. When you need more than a number, an entry can carry a note, a photo, a place, and your own fields.
Offline
Works fully offline
No sign-in, no network. Your counters open instantly.
Today
Flexible display modes
Show today, this week, this month, all time, or days since.
History
Notes and editing
Every entry keeps its amount, note, and timestamp — all editable.
Photos
Attach a picture
One photo per entry, shown full width in the history — proof, receipts, progress shots.
Location
Where it happened
Drop a pin on the map, or leave it off. Coordinates stay on the device with everything else.
Fields
Your own fields
Add number, text, or yes/no fields per counter — kilometres, mood, client, whether you needed the van.
CSV / JSON
Export any time
One counter or everything — counters, entries, notes, and custom fields, for analysis or a backup.
Widgets
Home and Lock Screen
Your counters at a glance, in the display mode you chose.
PIN
Hidden counters
Optional paid feature for tracking you'd rather keep private.
Beyond the number
An entry can carry the whole story
A count is often not enough on its own. Switch on only the extras a counter needs — the log sheet stays a single number for the rest.
Photo
Take one in the sheet or pick from your library. It fills its row in the history, and opens full screen with a tap.
Location
A map with a draggable pin. Use the spot you’re standing in, or set it by hand — and never at all if you’d rather not.
Custom fields
Define your own per counter: numbers like distance or weight, short text like a client name, or a yes/no switch. They export with everything else.
Privacy by design
Hidden counters leave no trace
Hidden counters are not visible in the main list unless unlocked with the correct PIN. The interface is built to avoid existence leaks.
No visible list
Hidden sets are never listed anywhere in the app.
No counts
Nothing indicates how many hidden counters exist.
No discovery
There is no way in without the correct PIN.
Never exported
Excluded from exports and from every widget.
Your data stays on your device
Loendur does not collect counter data, does not require sign-in, and does not connect to external services. Optional anonymous analytics can be switched on — and off — at any time.
