Geotack
Geotack stamps the date, time, address, coordinates and a small street map onto your photo the moment you take it. Send it anywhere and the proof goes with it.
Address, latitude and longitude, GPS accuracy, date and time zone, drawn on the viewfinder exactly as they will be saved.
Project or company name, notes, photo numbers (#1, #2, #3…) and saved places like "Smith Residence". The Field report layout puts it all in a clear table.
Pick photos with Android's photo picker, choose the place, and stamp them all. Each keeps the date it was taken.
A small OpenStreetMap street map with a pin when you're online, a plain coordinate grid when you're not. Small, medium or large; top or bottom.
The time comes from your phone's clock and the location from your phone's GPS. Geotack prints the GPS accuracy (± metres) so whoever sees the photo knows how exact the spot is. The address comes from Android's built-in geocoder and needs a connection; offline, the stamp shows coordinates.
Yes. Besides the visible stamp, Geotack writes the GPS position, date, time zone and a short note into the photo's EXIF data.
No. New photos are saved to Pictures/Geotack. To stamp older photos you pick them with Android's photo picker, so Geotack only gets the photos you choose. Android's picker removes location from shared photos, so you choose the place yourself.
A stamp shows what your phone reported at that moment. Geotack doesn't claim to be tamper-proof; it shows the accuracy and keeps the EXIF data so the photo carries the same details in two places.
Two layouts (Field report and Travel) unlock for good with one short optional video, and batches over ten photos ask for one video. A full-screen ad may appear at most every few minutes, only when you leave a finished batch, Recent photos or Settings. Never an ad between shots or on the camera. Nothing to buy.
