While I personally rarely work I in the field, especially during recent times, I do quite often use my mobile device for day to day tasks like time tracking (with harvest) in order to accurately keep track of time spent on clients for invoicing.

However electricians, plumbers, handymans and the likes can not do without mobile devices anymore, that is why this has become a requirement for any system now.

The possibilities of mobile web applications (also known as PWA) has increased drastically in the last few years ams are in general fast with support for push notifications add well.

That is the very reason we are doing a complete overhaul of our job tracking mobile app, which we hope to release before the end of the year.
