Signing in has changed. Owners now sign in with their email and a password; staff sign in with their phone number and a password the owner gives them. Codes by SMS are gone. If you already use Tetrin, tap "Forgot your password?" on the sign-in screen and we will email you a link. Staff members get their new password from the owner. Reports on your phone. Three views that until now lived only in the browser: when cars actually arrive (day of the week against hour of the day), how the month went day by day, and your branches next to each other. Your own currency. A new car wash is set up in dram, ruble, dollar, euro or lari, and amounts in currencies with cents are now counted correctly. Team and Services rebuilt. Adding a washer or a new service no longer sits below the end of a long list. The app now opens in Armenian, with English and Russian one tap away on the sign-in screen. Face ID stays off until you switch it on, and it guards only the way in, not every screen. Long client lists open without the pause, and screens now say when they are loading instead of showing nothing. A discount on a bill is now spread across the services on it, so the services column in a report adds up to the revenue above it.

Three languages Tetrin now speaks Armenian, Russian and English. Switch the language inside the app at any time. Several locations Run more than one wash from one account and switch between them without signing out. Prices by vehicle class Define your own classes and set a separate price for each one. Two washers, one car A car washed together counts once, and the pay is split between them. Safer sign in Confirm your phone number and use a six digit access code. Signing in from an unfamiliar device asks for a code from SMS. Rebuilt reports Months as a chart, shares as a ring, and every number opens the list behind it. Payroll day by day See what each person earned for every working day, and record a payout for a specific day. The open shift on the Lock Screen While a shift is open it stays visible on the Lock Screen and in the Dynamic Island. Every car remembered Search your clients, open the full history of a single car, and see what it has left over time. Also in this update: a new app icon, redesigned screens across the app, faces instead of initials, and notifications about shifts and new records.
