iMeter Reader is the smart way to track your electricity, gas, and water meters. Add a meter, scan readings with the camera, and see exactly how much energy you use โ and what it costs you. Energy contracts are optional add-ons you attach to a meter for full tariff tracking. Whether you rent, own your home, or share a flat, iMeter Reader helps you document meter readings consistently, avoid surprise back-payments, and spot unusual consumption spikes early. โ WHAT iMETER READER DOES โ โข AI METER SCANNING Point your camera at the meter display and the reading is captured automatically. It runs on your device first โ instant, offline, and private. When a meter is hard to read, optional cloud AI steps in for a confident result. Works with analog (Ferraris), digital, and smart meters. โข ELECTRICITY, GAS & WATER Track electricity and gas meters โ and hot and cold water meters too. Single- and dual-tariff (day/night) electricity meters are supported. Manage your main home, holiday flat, small business or heat pump meter, all in parallel. โข AI ASSISTANT Ask the built-in AI assistant questions about your meters, contracts, bills, and consumption in plain language. โข UPLOAD OR PHOTOGRAPH A CONTRACT OR INVOICE Upload a PDF โ or photograph a paper contract or bill โ and AI fills the form for you. iMeter Reader automatically detects whether the document is a contract or an invoice, then extracts tariff name, provider, base price, price per kWh, annual consumption, monthly payment, contract length, notice period, price guarantees, and sign-up bonuses. โข RUNNING COSTS & USAGE PER CONTRACT The meter comes first โ add a contract whenever you like. iMeter Reader then tracks the consumption inside the contract period, recalculated automatically each time you add a reading dated within it. Enter your prices and it shows your accumulated running costs and total usage to date โ and reminds you before the contract ends or a price guarantee expires. โข EMAIL YOUR PROVIDER Need to contact your energy provider? If they're listed in the app you can email them directly; if not, start from a built-in template. When your contract details (provider, meter number) and your saved profile address are filled in, they're placed into the email automatically โ you just check it and send from your own device. It all happens locally, so your data stays private. โข USAGE ANALYSIS & CHARTS Generate bar, line, or area charts per meter. Compare months and spot seasonal patterns at a glance. โข READING REMINDERS Set weekly, bi-weekly, or every-4-weeks reminders. โข ELECTRICITY & GAS TARIFF COMPARISON โ PER METER Compare tariffs for a specific meter without leaving the app, powered by CHECK24 (Germany) โ no account needed. Open it from the meter or its usage chart: the postal code and an annual consumption estimate come from that meter, and ten common filters start with a pre-set selection you can change, clear or reset. Filters are saved per meter on your device. Loads only with your explicit consent. โข PRIVATE BY DEFAULT Readings stored locally โ AI features opt-in only. No forced sign-up, no ads, no background tracking. Optional AI features and the tariff comparison use the cloud only with your explicit consent โ everything else runs locally. **Manage your devices** in Settings โ see where iMeter Reader is installed and sign out remotely. Anonymous usage statistics (counts only) can be turned off any time in Settings. โ WHO IT'S FOR โ โข Renters who want to check utility bills โข Homeowners with heat pumps or solar PV โข Flatshares with shared electricity, gas, or water meters โข Small businesses and home offices โข Anyone planning to switch providers who needs reliable usage data โ ACCESSIBILITY & LANGUAGES โ iMeter Reader is available in English, German, Arabic, and Turkish โ including full RTL layout for Arabic. Dynamic font sizes, high contrast, and system dark mode are built in.
