Zählwerk

Meter reading? Photo. Done.

One photo. All the answers. All in your hands.

Zählwerk reads your electricity, gas, water and heating oil meters from a photo – no typing. The app recognises the meter number and the reading, assigns it to the right meter and keeps the photo as a receipt.

Already have readings? Import your existing data and start right away with your consumption history – so clear that you'll actually enjoy looking at it.

Beautifully designed in British Racing Green – plus two more themes, an elegant light one and a dark one.

No account. No ads. No tracking. No forced cloud.
Your data stays with you – right on your device.

Photograph your meter instead of typing
Take a photo of your meter – Zählwerk recognises the meter number and the reading and checks the value against your previous readings.
• mechanical dial meters
• digital electricity meters
• consumption and feed-in on bidirectional meters
• warning on unusual or decreasing values
• reading date taken automatically from the photo
• the photo is kept as a receipt
• older photos from your gallery work too

Understand consumption and costs
Your readings turn into an analysis automatically:
• consumption and costs per month and year
• consumption per day
• comparison with the previous month and the average
• monthly chart
• calendar year or your own billing period
• multiple addresses and meters, with direct comparison
No need to read on the first of the month – Zählwerk spreads your consumption across the months day by day.

Look ahead instead of being surprised
Enter your unit price, base price, instalment and billing period. Zählwerk calculates your expected costs and shows whether you're heading for a back payment or a credit.
Price changes with an effective date are taken into account. The simulator shows what an electric car or extra use would change.

Photovoltaics and wallbox
With a PV system, Zählwerk records grid consumption and feed-in separately and includes the feed-in tariff.
With a supported wallbox (currently Easee) you can see what share of your electricity goes into your car.

Meter data from your home network
Zählwerk can also fetch readings directly from your home network – no photo needed:
• Wi-Fi reading head on the meter
• camera reader for dial meters
• smart home hub or logger
• any other address that delivers a meter reading
The data stays in your home network.

Your data, your rules
• readings, photos and contracts stay on your device
• optional backup to a cloud folder of your choice – with automatic sync between your devices
• backup including receipt photos
• CSV export and import
• optional biometric lock
Photo recognition your way: Zählwerk recognition, recognition directly on the device, or your own key with an AI provider of your choice.
Zählwerk recognition analyses the photo and discards it immediately – not stored, not used for AI training.

Stop thinking about reading day
Set a day and time. Zählwerk reminds you of the next reading every month.

Thought through
• meter replacement without losing your data
• warning on duplicate readings on the same day
• mark readings as "reported to the supplier"
• filter and edit your history
• German, English, French
