Meter Readings: Gas & Water

Keep track of your energy consumption and costs – whether electricity, gas, water, district heating, heat pumps, oil, pellets, or photovoltaics (PV).

With “Meter Readings: Electricity Gas Water”, you document meter readings, deductions, and consumption easily and reliably on your iPhone or iPad. All data remains 100% on your device – no cloud, no account, no ads, and no tracking.

From apartments to houses, from standard meters to complex PV systems, battery storage, and heat cost allocators: The app supports diverse setups, helping you evaluate usage, prepayments, and billing forecasts transparently.

WHY THIS APP?

Many households still read meters manually. This app was built specifically for that: simple, reliable, and strictly privacy-focused – completely offline and without smart meters.

Complex setups are supported:

• Photovoltaics, battery storage, and wallboxes
• Virtual meters for self-consumption and autarky rate
• Prepayment forecasts (credit balance or arrears)
• Bi-directional and feed-in meters
• Ferraris meters with reverse running (balcony solar)
• Heat cost allocators (HCA) and tank meters (oil, pellets, LPG)
• Multi-tariff and multi-register meters

All data remains 100% local on your device.
