Without question, I will use my desktop over a phone app if at all possible unless I am on an out-of-town route of several shops with no narratives, in which I will use the isecretshop app or Presto, both of which have their faults that a pc does not have. Gas stations now require using the Presto app, but I always save for later and check the report when I get to a pc or laptop. Presto often loses my photos, so this is necessary. Even if submitted a MF shop with my smartphone while away from home, I woud use the MF website instead of their app which does not work well.
1. Most phone apps do not work as well as website apps; Some do not work at all.
2. Phone app display is so tiny and often does not display the same as a website.
3. Narrative-intensive reports are practically impossible compared to typing on a normal size keyboard with both hands. And no, speech-to-text is not an acceptable substitue unless reporting onl a few words.
4. I have 3 widescreen monitors on my desktop and can open 6 windows side-by-side (time is money).
5. There is no practical drag-and-drop ability on the phone app (time is money).
6. It is easy to type in MS Word and copy and paste into a web form with a computer (data backup).
7. Phone apps often malfunction in the middle of a report and lose data.
