iMeter Reader vs Zählerblick

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 — 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. — WHAT iMETER READER DOES — • ELECTRICITY, GAS & WATER Track electricity and gas meters — and hot and cold water meters too. Single-tariff, dual-tariff (day/night) and — new — two-direction solar meters are supported. Manage your main home, holiday flat, small business or heat pump meter, all in parallel. • 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 — always marked as approximate. • READINGS BY HAND OR BY PHOTO Type the reading in seconds — or let the optional AI read it from a photo of the meter display. Works with analog (Ferraris), digital and smart meters. • 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. • AI ASSISTANT Ask the optional built-in assistant questions about your meters, contracts, bills and consumption in plain language. • RUNNING COSTS & USAGE PER CONTRACT The meter comes first — 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 — and alerts you before the contract ends or a price guarantee expires. • 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 — you check it and send from your own mail app. Everything happens on your device. • USAGE CHARTS Bar, line or area charts per meter. Compare months and spot seasonal patterns at a glance — solar feed-in has its own colour. • 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. • GUIDED START A short walkthrough explains your first meter, your first reading, signing in and the contract form — step by step, skippable at any time. • YOUR DATA, YOUR DEVICE Readings stay on your device. Sign in only if you want a cloud backup of your meters, readings and contracts — 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 — 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 → Privacy. — WHO IT'S FOR — • Renters who want to check utility bills • Homeowners with heat pumps or solar PV • Flatshares with shared electricity, gas or water meters • Small businesses and home offices • Anyone who needs reliable usage data — ACCESSIBILITY & LANGUAGES — iMeter Reader is available in English, German, Arabic and Turkish — including full RTL layout for Arabic.
