We do not offer any separate mobile app for courier services, thus the only option is to use PickmeApp. The app itself doesn’t differentiate between ride-hailing companies and courier companies. As it is still not a branded mobile app but a generic one, it will show the services of all the companies available in your region. You cannot isolate this app to your services only.
Also, if you create a Classic tariff, and another company in your region has this tariff as well, you will not be able to use Custom name for this tariff. The app will show the default name (Classic) instead of the custom name given in your company settings. So you can play with tariffs, choose a tariff with a suitable icon which is not used by other companies of your region (it may be some rarely used tariff), and give it a custom name. If the other companies of your region do not have this tariff, the app will show your custom tariff name.
The same logic applies to the fee settings. I’ve explained it in more detail in my previous response. So my advice would be to play with tariffs and find the one that is not used by other companies of your region.
