Meter reading app
Open DialDay on your reading day, look at last month’s photo of the dial, type today’s number under it and take a new photo. It shows what you used since last time and how the months compare.

The reading keeps the same number of digits as your meter, leading zeros included. Under it, DialDay shows what you used between the two.
The reading screen opens on the photo you took last time and the number you typed under it. Type today’s number on the large readout, take a photo of the dial, and DialDay shows how much you used since the last reading before you save.
If a number is lower than last time, DialDay asks whether the dial went past its top number and started again from zero, or a new meter was fitted. A reading three times your usual use, or with more digits than the dial has, gets a second look before it is saved.
Gas, electricity, water, heating oil, LPG, heat meters and solar export. A meter with day and night registers gets a reading for each. Gas read in cubic metres or hundreds of cubic feet can show kWh, using the calorific value printed on your bill.
A chart estimates each month’s use by spreading it evenly across the days between readings, so a reading taken on the 3rd does not put a whole month in the wrong column. This year’s total sits under it, with a comparison to the same month last year once enough history is there.
Pick a day of the month and a time. DialDay reminds you on the day at the time you pick, and again two days later if a reading is still missing. A “Reminders not arriving?” screen shows what your phone has switched off.
Enter your unit rates, standing charge and VAT or sales tax, and record tariff changes by date. DialDay estimates the cost of each reading from the rates you entered. A PDF of every reading in a date range with a small copy of each dial photo, or a CSV for a spreadsheet.
There is no account and no sign-in, and DialDay does not upload your readings or photos. Backup makes one file with every photo inside, so you can move to a new phone; restoring replaces what is in the app with the backup. The app sends crash reports and screen-view statistics, and neither includes your readings or photos.
DialDay does not pass readings to your energy or water supplier. Use the number on their app or website as usual, and keep the photo here.
A cost is worked out from the rates you type in. Your supplier’s bill can differ, for example if they estimated a reading or changed a rate.
