I recently fell in love with mushroom hunting. Initially, I relied on paper and pencil to keep track of my finds and forays. But that left me with incomprehensible directions and descriptions.

Having a good log is the cornerstone of making mushroom hunting more approachable.

So I searched for a technology to help me. I found apps that promised to identify mushrooms through photos, but I didn't want that. I wanted an app to help me keep track of my finds.

Thus, the idea to create Mycolog was born.

Mycolog was created over the course of several months. I developed this app while testing it in the field as I hunted mushrooms this past season. I think I've arrived at some very useful features that would otherwise be nearly impossible without Mycolog:

(1) Offline map support -- No one gets great cell reception in the woods, but everyone has a GPS signal
(2) Pinpoint your location and altitude -- Find a mushroom once in a spot and you'll surely find it again there
(3) Easy input of common attributes -- Every mushroom book starts by advocating you log these
(4) Optimized for one-hand use -- Mushroom in one hand, log in the other

I hope you enjoy Mycolog. It's been an incredibly useful companion for me.

I am providing this app free-of-charge to other mycology enthusiasts, but should you wish to support my continued development efforts, you can donate via the Settings page :).

=== Please Note ===
If you are looking for an app to automatically identify mushrooms for you, this is not it.

So close and yet so far

I am so sad because this app is almost terrific, however...with iOS 12.0, the photo function is unusable. If I want to use a photo from my library, they are in a somewhat chronological order from older to newer (a real problem when you have thousands of images). I say newer not newest because a my last photo was not at the end. Very disappointing after all that swiping. There is no way to access photo folders, and worst of all, when you take a photo from within the app and save it, it is replaced with the oldest image in my photo library. Every mushroom I’ve photographed so far has been transformed into the same lovely necklace. When the photo thing is resolved, I’m sure I’ll give this app 4 or 5 stars...but until then it is unusable.

Yikes that sounds very frustrating! I will take a look at that issue. I have not done much testing on iOS 12, so hopefully it's something simple.

Amazing Program

When it comes to identifying fungi, the devil is in the details and and if that’s the case then this app was made with a whole demon invasion in mind. It’s a one stop shop for all components of mushroom identification. It has colour gradients for the cap, stipe, and spore print which is a huge help when you aren’t sure if you should call that one mushroom you found brownish-yellow or yellowish-brown. The UI is sleek and clean and the features it offers are amazing

Photo support

I downloaded this a couple weeks ago. Today I got a chance to go hunting, found my first mushroom and got all set to add it to the log. I could not get a picture added. I tried taking and uploading from photo album. Would love to figure this out.

Developer Response ,

Very sorry to hear that. The library I have been using to handle the camera + photo album is no longer being actively worked on, which seems to be causing some unexpected behavior.

I will be releasing a new version of the app in the coming weeks, with some fixes to how photos specifically are handled. Hopefully that will fix the issues you are seeing. If not, please let me know via I want to make sure everyone can actually use this :).
