I remember too when I started to use my iphone to track FS work. A brother had written an iphone app called "my time" which used the gps to track your place in the territory, counted your time and allowed to use the calendar to mark down the visits, return calls, etc. You could then hit a button and submit the report to the elder at the end of the mont. This was 2008-09. I showed it to one elder and, as usual, technology seems to breakdown when you need it the most (not when you want it the most). Signal in our territory was bad. So he immediately used that to bash the idea and scold me for holding down the progress as I was waiting for my phone to get signal again. He said this is what happens to everything man invents. It fails. After returning from the 2014 International convention, where GB Jackson used a tabled to give his speech, I was scolded for using my tablet to give an assignment, instead of printing my assingment. Later on another elder told me that it was ok to use the tablet for the assingment but not for reading the bible.
I did not go to the meeting so I am not sure what they may have said here in our part of the US. I will ask though, one of my coworkers has his meeting today.
