The following works for me:
I am a total fan of Timestamp Camera, a free phone app which imprints the timestamp AND location on the picture as it is being taken. It even has a cool feature to superimpose a translucent overlay of the MAP with location dot in the upper right corner.
As the pictures are timestamped, I will also accept them for timed controls. You and/or your bike need to be in the picture (SR-600 type of documentation), and the picture should be of something which is clearly the control location.
Like so:
(before I discovered the text formatting options, but it is an unambiguous pic of the control!)
Settings changes for best readability:
Position - select "One line to the edge" and "Time in below"
Format - yyyy/mm/dd, lat/long, City/State; optionally select Display Map
Font - default? I use ArialMT
Input - if you wanted, you could put your name and route name/number.
Opacity - move the background opacity to about 1/3 of the slider.
For total fancyness, in the menu (upper row of icons), if appears that you can set it up to send email to someone as each pic is taken. It creates the email, but you still need to tap Send. Still Very Cool.
