Yes, on iOS a calculated Quote can be used to overwrite the taximeter amount.
Tap on ‘MTR’ next to the fare and cycle through the different modes:
MTR -> FIXED -> FIXS -> FIXS+ -> MTR
FIXED: App will ask for a fixed price.
FIXS: When a Quote has been calculated and when your location’s and Quote’s City / Area are identical, it will switch to FIXS and overwrite the taximeter with the amount from the Quote.
FIXS+: The meter amount already accrued will be increased by the amount from the Quote. This is useful in a scenario in which you want to know how much the trip from your current location to your destination will cost and taximeter is already running.
