iMeter Reader

Read full description

iMeter Reader is the simple way to keep track of your electricity, gas and water meters. Add a meter, enter the reading by hand or by photo, and see how much energy you use โ€” and roughly what it costs you. Energy contracts are optional add-ons you attach to a meter. Whether you rent, own your home or share a flat, iMeter Reader helps you document meter readings consistently and spot unusual consumption early. โ€” WHAT iMETER READER DOES โ€” โ€ข ELECTRICITY, GAS & WATER Track electricity and gas meters โ€” and hot and cold water meters too. Single-tariff, dual-tariff (day/night) and โ€” new โ€” two-direction solar meters are supported. Manage your main home, holiday flat, small business or heat pump meter, all in parallel. โ€ข SOLAR / PV: TWO-DIRECTION METERS One meter, two registers: energy taken from the grid (1.8.0) and energy given to the grid (2.8.0). Enter an optional feed-in price on the contract and the app shows an approximate earned amount on the contract card and under the chart โ€” always marked as approximate. โ€ข READINGS BY HAND OR BY PHOTO Type the reading in seconds โ€” or let the optional AI read it from a photo of the meter display. Works with analog (Ferraris), digital and smart meters. โ€ข CAPTURE A CONTRACT OR INVOICE WITH AI Upload a PDF or photograph a paper contract or bill, and the optional AI fills the form: tariff name, provider, base price, price per kWh, annual consumption, monthly payment, contract length, notice period, price guarantee and bonuses. The app detects whether the document is a contract or an invoice. You review every field before saving. โ€ข AI ASSISTANT Ask the optional built-in assistant questions about your meters, contracts, bills and consumption in plain language. โ€ข 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 each time you add a reading dated within it. Enter your prices and it shows your approximate running costs and total usage to date โ€” and alerts you before the contract ends or a price guarantee expires. โ€ข 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. Your contract details and saved address are placed into the email automatically โ€” you check it and send from your own mail app. Everything happens on your device. โ€ข USAGE CHARTS Bar, line or area charts per meter. Compare months and spot seasonal patterns at a glance โ€” solar feed-in has its own colour. โ€ข READING REMINDERS PER METER Set a weekly, bi-weekly or every-4-weeks reminder for each meter. Tap the notification and the reading sheet for that meter opens. โ€ข GUIDED START A short walkthrough explains your first meter, your first reading, signing in and the contract form โ€” step by step, skippable at any time. โ€ข YOUR DATA, YOUR DEVICE Readings stay on your device. Sign in only if you want a cloud backup of your meters, readings and contracts โ€” the cloud icon shows the backup state. No forced sign-up, no ad networks, no tracking. AI is opt-in and runs on servers in Germany only, in line with the GDPR: your data never leaves Germany, is not stored by the AI service and is never used to train AI. Everything else works offline. Personal energy offers for your area โ€” coming soon (Germany). Share iMeter Reader with friends straight from the app. Anonymous usage statistics (counts only) and crash reports can be turned off in Settings โ†’ Privacy. โ€” WHO IT'S FOR โ€” โ€ข Renters who want to check utility bills โ€ข Homeowners with heat pumps or solar PV โ€ข Flatshares with shared electricity, gas or water meters โ€ข Small businesses and home offices โ€ข Anyone 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.
