taxiID provides a platform that taxi companies use to run their work. Rides are planned and followed with track and trace, and passengers book through an app or a web booker. The platform also covers a module for regular customers, administration and invoicing, and links to the organisations that commission rides and to subcontractors. taxiID says thousands of taxi companies use it every day.
The iOS application has been in the App Store since 2018 and was about seven years old at handover.
The taxiID iOS application has been in the App Store since 2018 and was about seven years old when Chief took it over in 2025. taxiID was looking for a party to take over maintenance of that app and keep releasing it.
The assignment was maintenance of the existing taxiID iOS application, with the aim of safeguarding its stability and functionality. The starting point was mapping how the app is put together and what it depends on.
Maintenance calls for being able to build an app, test it and take it to the App Store yourself. Chief made that the first step, so that changes would then reach users along a fixed route.
Chief took over maintenance of the app. Chief first mapped how the app is put together and what it depends on, then made sure the app could be built and tested on Chief's own machines. From there the route continued to test versions and on to the App Store.
While working through the reported items, Chief tracked the work as a list of open items. Chief took the code into its own working environment, so that colleagues at Chief could review changes before they went to production. Chief wrote down the build and release procedure, so more than one developer at Chief could pick the app up.
What users ran into in everyday use decided which improvements came first. Chief also delivered new functionality, including navigation and notifications of new ride offers, where users can choose between two alert sounds.
Chief released the app in the App Store several times during the assignment. The version available there now was published in 2026. Improvements, problems resolved from everyday use and new functionality reached users along that ordinary route.
Chief wrote down the build and release procedure, so that inside Chief it is clear how a new version comes about. Chief kept its own list of the items that were open while reported problems were being worked through.
Chief took the code into its own working environment, so more than one developer at Chief could build and release the app.
taxiID placed the maintenance of its iOS application with Chief. Chief built, tested and released the app, resolved problems that came out of everyday use, added functionality around navigation and ride notifications and wrote down a build and release procedure more than one developer at Chief could work from.
