Keep an eye on your consumption – Simple, fast, and completely private.
The Meter Tracker is the perfect tool for documenting your meter readings for electricity, water, gas, or photovoltaics directly at the meter box. We believe: A good tool should do exactly one thing perfectly – without overloading you with unnecessary features or harvesting your data.
That's why this app takes a refreshingly different approach:
🛡️ 100% Private & Offline
No forced cloud sync, no registration, no hidden servers. Your meter readings are private and never leave your smartphone. Data is stored exclusively locally on your device.
📊 True Analysis Instead of Blind Numbers
See at a glance how your consumption is developing: clear bar charts by month or year, statistics (average, trend, min/max), and an optional consumption forecast for the next month. The app always shows exactly what you have read – no estimates, no invented intermediate values.
💡 One Meter per Reading – Full Control
Do you have a dual-tariff meter for peak (HT) and off-peak (NT), or measure feed-in and consumption separately? Simply create a separate meter for each value. Need a combined total, e.g. from cold and hot water meters? A virtual combined meter automatically adds up the consumption of two meters.
🏷️ Tags & Organization
Organize your meters with freely chosen tags – e.g. by apartment or building – and filter the overview with a single tap.
💰 Keep an Eye on Costs – Optional, Not Intrusive
If you want, simply enter the unit price and base fee for each meter – and instantly see what your consumption costs. Tariff change? No problem: The app manages multiple tariffs with validity dates and automatically calculates them historically correctly. For photovoltaic meters, the feed-in tariff is calculated instead of costs. If you don't need this feature, just turn it off.
⚡ Lightning Fast & Reliable
Taking a reading takes just a few seconds – and the built-in plausibility check warns you immediately if you make a typo. A traffic-light status also shows at a glance whether a meter is up to date, getting old, or hasn't been read in a while.
All features at a glance:
• Electricity, water, gas, district heating, photovoltaics, virtual combined meters, and custom meters
• Free choice of units (e.g. kWh, m³, liters) and currency symbol
• Tags for freely organizing and filtering your meters
• Consumption chart per meter with a flexibly selectable time period
• Analysis screen: bar charts (month/year), statistics, optional two-meter comparison
• Consumption forecast for the next month – based on your own readings
• Optional cost calculation with complete tariff history for correct historical billing
• PV feed-in tariff: photovoltaic meters show the generated revenue instead of costs
• Traffic-light status: see at a glance which meter needs a new reading
• Reading reminders with your preferred interval and a quiet-hours option
• Support for backwards-running meters
• Built-in flashlight for dark basements and meter boxes
• CSV and PDF export for spreadsheets and print-ready reports
• Backup & restore: encrypted, compressed local backups – ideal when switching to a new smartphone

• Built-in user manual directly in the app
Honest and fair: This app is a premium tool. Free of charge. Use it undisturbed forever. No ads, no in-app purchases, no subscriptions, and no data collection.
🔄 Switching from ECAS?
If you want to bring your data from the ECAS app (Energy Consumption Analyzer), you can import it directly in the app – under "Data Import → ECAS Import", all meters and readings are transferred automatically.
