This I enjoy

Great app. Very simple and easy to use. I use the timer, when I start my ministry, timer can be paused when not in field service, then restarted when one restarts. Excellent for tracking, time and placements in the ministry, tracks placements made with newly interested ones and Rv's. At the end of the month one can use the feature to consolidate their reports, as well as keeping track of how one is doing on a monthly basis. Very handy too with being able to keep a record of interested ones all within easy reach of the same app. Great work.

Excellent App!

Thank you so much for your time & effort spent on developing & maintaining this wonderful app. I just love it. I’ve been using this app for many years now. Such a helpful tool. When I recently upgraded my iOS it looked like I had lost all my time. But with the ‘recover lost time’ function in the ‘user’ tab I was able to recover it all 😅. So thoughtful of you to have included this function. Once again, thank you!

Field service (v3.3.5)

Very quick and easy to use. The best field service app I have used. As it is quick and easy to keep track of placements and RVs. The only improvement that would be of great help, is to sync it across all my devices. Then I could add details to my account on my tablet or phone.

Developer Response ,

All of your calls are automatically synced via iCloud if you have that turned on. Just make sure that the user in the "Users" tab is the same on both devices. Alternatively, you can email a backup to another device and it resolve conflicts between devices. Emailing a backup to another device is the only way to move your time entires and that doesn't do conflict resolution. Please go to the "Offers" tab and press the "Instructions" button to learn more of the program's functionality. Thanks!
