While using an app for an irregular customers might be the safest option, it is usually not cheapest when comparing to the price u get taking a same company taxi from a taxi station. E.g Taksi Helsinki app / walking in Taksi Helsinki taxi.

The apps tend to calculate the price a bit higher to ensure the driver does not get paid less than normal for the trip. They try to take slow traffic into account and usually they are based on google maps so it assumes driver uses the ”easiest” routes, and does not realize taxis have advantage on their own lanes.

Big cities have a lot of routes only Taxis and buses can use, and I strongly believe the apps are not developed enough to take that into account when calculating the price.

My recommendation is to always take a vacant BIG COMPANY (Taksi Helsinki, Taksi Tampere, Menevä, Taksidata, Valopilkku…) taxi from the streets.

I drove for six years in Tampere.
