Yep :-D thanks! Makes me really happy that you know about Photo Find!

Ha I actually made an iOS & watchOS app based on that side of the equation after thinking "what's the minimum input I can provide for good hydration reminders?"

It gives a reminder to drink water any time it's been three hours since you've peed...

Not super scientific, but less of a hassle than tracking water input and it tends to adapt well to factor in things like exercise where more water is needed. It also tends to even out over time when drinking alcohol or coffee. Urine color can also vary depending on foods, like how B12 makes it fluorescent yellow, so the time factor can be another useful indicator.

I don't have much experience with DSLRs and didn't even know there were GPS modules for them, but that makes sense and is awesome!

But yep it just pulls the lat and lon from the EXIF data, so it should work fine. The standard for EXIF is degrees, minutes, seconds and then a separate "Ref" value for N or S.

I have to do a little math on those values to turn everything into a decimal format, but based on this standard I would assume everything saving location in EXIF data would use this same format so it should all be compatible:

If you test it, let me know!

Yeah! Awesome to hear! I was already thinking about adding that because sometimes some driving or public transit is needed to get within walking range haha

Oh yeah! That part sucks. I should have done more name research first. I always tell people to search "photo find hiking" (quotes not necessary) because that's easier to spell than my last name and it's the only app that comes up.

Haha not a premium feature! Sometimes there are calibration issues. I meant to add some calibration checks and user feedback about needing to calibrate at some point.

Try rotating your phone around in a circle a bunch and then see if the compass starts moving and correcting itself.

I thought it was passive, too. I've googled a little in the past and some people say it's in the same chip as the cellular radios (and the whole chip gets knocked out in Airplane Mode). Others say the amplification of signals necessary could cause interference.

Haha I know, I know... you're not the first to ask about Android!

The reason I tried JavaScript first was to start off cross-platform, but when that failed I developed for the hardware I use.

However, I've been meaning to try out some Android development, so maybe at some point...

Sure, but have you ever tried navigating to a photo that way?

The map doesn't show your location, and even if it did you would still need some kind of compass arrow, like the Google Maps app for iOS shows, to be able to navigate to it.

Also, this works by pasting a photo from the clipboard instead of just using photos in your library.

Thanks! It's about time.

HA! That's amazing.

It's a pretty good point actually! Because Airplane Mode disables GPS on the iPhone.

OK, sorry you feel that way about SI!

As long as you already have the app and photo on your phone it just uses the compass and GPS, which are both sensors built in to the iPhone and don't require internet.

Thanks! I really appreciate hearing that!
