Android Apps You Should Have For Geocaching

It’s really easy to stay solely focused on just geocaching and forget to look around at what else might be useful for hunting down those little boxes. By way of example, while visiting I a discount store recently, I came across an extendable claw that would be perfect for grabbing out-of-reach caches.

With smartphones getting smarter, it also seems there are a wide range of applications out there that can help geocachers. Some of them are obviously useful, whilst others are not. Here are a few gems I’ve stumbled across following my recent Android acquisition:

GPS Averaging

Want to place a new cache with your Android phone? Then you’ll need this app. Help remove the tarnish from the image of smartphone co-ordinates by averaging your own. Not only does this app obtain great co-ordinates but it allows you to export in GPX or KML and send that information off via email.

The free version offers all this app’s features but has an ad, or you can pay US$1.50 for the ad-free version and support the developer at the same time.

It has an average rating of 4.2, with the best comment from the market listing saying:

Rating 5.0 stars: Awesome support from this apps dev. I had a issue and he replied and fixed it quick. Awesome


Geocache Calculator

Your new best friend when it comes to solving geocaching puzzles, thanks to the more than 250 functions of this app. For starters, it will calculate or help solve ADFGX (en-/decrypt), ADFGVX (en-/decrypt), Alpha Numeric, ASCII:, Base16 (en-/decode), Base32 (en-/decode), Base64 (en-/decode), Base85 (en-/decode), Brainfuck/Ook, Caesar (en-/decrypt), Colors, Co-ordinates, Cross Total, Enigma, Formula Solver, GC Base 31 (en-/decode), Hash, Heatindex, Hint (en-/decode), Kenny’s Code (en-/decrypt), Morse Code,  and ASCII.

It also has a great range of extras; including four themes, three font sizes, six character sets, a dynamic user-interface, English and German translations, integration of myGEOtools, complete offline usage, no device permissions on required … quite frankly, there are so many functions I couldn’t possibly cover them all.

The free version doesn’t have ads, though you may prefer to purchase the donate version for US$5 to support the developer.

It has an average rating of 4.7, with the best comment from the market listing saying:

Rating 5.0 stars: Nothing short of “top notch” can be said in describing this program and its many, many options. Unbelievable that you can download it FREE!!


Tiny Flashlight + LED

How to describe this app? First and foremost, pointing out that it has 912,540 reviews with an average rating of 4.6 probably says it all. It’s the best flashlight app on the market and, when the natural light is fading and you’re trying to get that FTF before the rest of the hoard turn up, it will truly light up your world. It has an excellent range of different light functions, including a few that could be useful in an emergency (strobe and morse code!).

Even better, the app is free!

Rating 5.0 stars: Clean intuitive interface. Works nicely and reliably. Developer is responsive. Props for adding Morse code feature that so many requested. Verizon Samsung Galaxy Nexus LTE


Ultra Magnifier+

Looking for a needle in a haystack … possibly literally? Then this neat, wee app may be of use. It’s excellent for getting up close in areas where you are looking for something small or while trying to spot something odd. The addition of a light function means you can magnify even in the dimmest light.

Another great little app that is free!

It has an average rating of 4.8 and the best comment in the market listing says:

Abi on January 19, 2012 (Samsung Galaxy Nexus with version 1.0.4)
Rating 5.0 stars: Most useful app seen so far in smartphone. Has minor problem with automagnifying option with Galaxy Nexus. Must first take picture then corrects the problem of keeping automagnifying turning light on and off. But still super!


Where’s My Droid

There’s nothing worse when you’re out and about than losing a vital piece of equipment. It can be quite easy at the end of a caching trip to put your GPSr down on the grass and forget to pick it up again when you leave. With Where’s My Droid, you won’t have to worry so much about doing that!

This app lets you locate your phone by sending a codeword or sentence to it via text message from another device. Depending on the word/set-up, the phone will either send you back its current co-ordinates or, if you’re in the vicinity, sound a tremendously annoying alarm that will allow you to track it down.

Yet another fantastic app that is free!

Anthony on January 29, 2012 (Samsung Droid Charge with version 4.0.1)
Rating 5.0 Stars: Works, amazing life-saver, no more anxiety attacks when I mis-place my phone. Also the upgrade is totally worth it! Being able to lock your phone from any other device: laptop, tablet, other smartphones etc … can be a life-saver especially if you have personal info or images you don’t want others to see. You set a pin to unlock it . A def must-have!!

Metal Detector

A lot of people may not realise than many smartphones now have in-built magnetometers. Aside from providing that all-important function of a magnetic compass, this can also help you utilise your phone as a metal detector.

I downloaded this app as a gimic and never thought it would be of any use to me in geocaching. However, just days ago, a new cache was published by one of our sneakier local hiders where this app was invaluable. The GC.com listing hinted that part of the cache might be magnetic and that this would be useful for recovering the cache. It also gave the impression that this might be another ‘needle in a haystack’ search. Once at the approximate GZ, I quickly found the cache by waving my phone all over the place with this app activated. So it’s well worth a try!

Free again, with an average rating of 4.2 in the market. The best rating says:

Rating 5.0 Stars: I thought this was fake but am clearly wrong, I work in a bowling alley, it can detect the solonoids when they are active meaning I can check soloniods without taking them off, great app ok metal detector great electro-magnet field detector.
