Tired of surprise utility bills? Meter Reading is the simple utility tracker for your electric, natural gas and water meters. Scan or type your meter readings, see what your usage costs so far, and know before the utility bill arrives whether you are on track or heading for a higher bill. No spreadsheets, no account, no hassle. SCAN YOUR METER IN SECONDS Point your camera at the meter and the app reads the numbers for you, right on your device. Works with digital displays and number wheels on electric, gas and water meters. Older dial meters? Type or speak the reading instead. YOUR UNITS, YOUR WAY kWh, CCF and gallons are preset for US meters. Therms, cubic feet or anything else you can type in yourself, for every meter. Gas meters in cubic meters can be converted to kWh automatically. KNOW YOUR UTILITY BILL BEFORE IT ARRIVES Enter your rate plan: price per kWh, base charge and monthly payments. The app does the math: costs to date, a forecast for the whole year and the expected credit or balance due. Tiered rates, rate changes and a plan comparison are built in, and a reminder tells you before your contract term ends. DASHBOARD: EVERYTHING AT A GLANCE Every meter gets its own dashboard: current reading, this year's usage with forecast, monthly trend, comparison with last year, a heatmap across all years and automatic insights when your usage looks unusual. Pick the cards you want and put them in your order. SOLAR, NET METERING AND HEAT PUMPS Virtual meters calculate what no single meter shows: how much solar power you use yourself, how much you send back to the grid and how much you buy from your utility. Start from a template (solar with grid export, solar with self-consumption, solar with heat pump) or write your own formula. Enter your export credit rate to see what your solar earns, and the heat pump meter shows your seasonal performance factor. BUILT FOR HOMEOWNERS, RENTERS AND LANDLORDS Manage multiple homes, rental units and properties, assign meters to each one and read all meters of a property in one go. Print a QR code for every meter and open the right one with a scan. Create annual statements and utility cost statements for your tenants as PDF. NEVER MISS A READING Set reminders for each meter: daily, weekly, monthly or quarterly. Add up to four photos, notes and tags to every reading, and mark the readings you have reported to your utility. SEE HOW WEATHER DRIVES YOUR BILL Outdoor temperature, rain and sunshine hours right next to your usage. Find out how much a heat wave or a cold snap really costs you in heating and cooling. IMPORT, EXPORT, BACKUP CSV import and export for readings, rate plans, payments and gas conversions. PDF reports to share. Back up your data to a file, with a reminder. PRIVATE BY DESIGN Your readings and rate plans stay on your device. No sign-up, no account, no cloud required. Light and dark mode, for iPhone and iPad, in 30 languages.

Verdict
The clearest difference is price: Meter Reading at Free against Grade Calculator's $1.99. Meter Reading also leads on iOS requirement (15.0 vs 18.0). Grade Calculator's advantage is ads (none vs shown) and update cadence (every 3 days vs every 2 weeks). On in-app purchases and device support there is nothing between them.
