Perhaps an example of the growing power of QGIS is how mobile applications have been integrated with this tool in recent years. Mobile applications are becoming popular in their use for data collection, particular in the field when researchers or data collectors are deployed to capture relevant geospatial data. These tools can now be integrated and work with QGIS as a way to interface with QGIS while you are on their mobile device.
Two popular tools that do this are QField, developed by OPENGIS.ch, and Input, developed by Lutra Consulting. These tools are very similar and both work off project files in QGIS so that they can work with and synchronize with a QGIS project. Both the tools are available on Android devices, while Input is also available in iOS.
