Best Photographers Tool Apps for Android

What Apps (for Android) do you use? I'm not looking for Apps that 'improve' the capability of the camera on your phone, e.g. Pro Camera or Camera Zoom FZ, but for one with tools like Sunrise/Sunset timings, Golden Hours, ND Exposure Calculator, Hyper Focal Distance Calculator, Colour wheels/grey cards, etc., etc.

I've tried Photographer's Tools Free and Photo Tools, but the location services of neither of those work with my phone (Sony Xperia Z1 Compact).

Any (free) options that anyone can suggest? Ones that recognise that Pentax cameras exist would be preferable.

The Photographer's Ephemeris (TPE) is something that I find useful for landscape photography..

DOF Calculator - does what the title suggests.

OS Grab-a-gridref - good for confirming both your OS map ref and Lat/Long.

PHOforPHO - another tool kit

DOF Calculator is useful for working out hyperfocal distances, and has Pentax cameras in it's database Edit: JohnX just posted that before me, I see).. DSLR Remote works as a remote for Pentax In fact only for Pentax) cameras, but doesn't work with the K3 for some reason.

I use 'Exposed' [by Braxis ltd] for ND exposures. Easy to use, just select the ND value, reference F-stop, and it gives the required shutter speed. You also have a count down clock to time the exposure.

Have a look at this set of tools.

Apps I use:

UK Tides - For beach shots
DSLR Remote - Needs a phone with IR blaster, but much better range than separate remotes.
PHOforPHO - Lots of useful tools in one app
DOF Calculator - Does what it says on the tin.
Sun Surveyor - does everything that TPE does but with added features, the best of which is an Augmented Reality view, that shows you the Sun path superimposed on the phone camera view when held up to the sky.

An Android app, windguru, for tides and winds, all over the world.

I must say I use a phone app for calculating 10 stop filter long exposure times now. Much easier than carrying a sheet of paper around like I used to. That's not Android specific though, just thought I'd mention it.

given the Camera's meter works through the lens, if you attach an ND filter then why isn't the camera's meter enough to tell you the correct exposure?

Photographer's Tools Free by The Zen Apps is a handy little tool too. Find it on play.google.com

It won't do it on a 10stop ND, where the exposure time stretches into eternity (well, on the way to ...)

Free app Exsate Golden Hour for golden and blue hour, moon phase and similar stuff.

Thank for all your suggestions - I'll be checking them out.
