new update!! (november 2021)

hey everyone, thank you so much for waiting so patiently for this, sorry it took so long to make proper updates. full clarity the pandemic and my own health hit a rough spot, and the amount of work i was able to do was few and far between. i cant express enough how grateful i am to everyone who continued to support me and wait patiently through it all while i recovered, thank you all so much from the bottom of my heart

ive redone the save/load system a bit to account for multiple save files, but you can continue to use the old save/load system, it is under load (old) and save (old)

the newest update includes a way to recreate your island from your in-game map. it's not 100% perfect since there is only so much i can interpret from the in-game map, but hopefully it will be a close enough jumping off point to help

most notably, water and paths cover up height information, so anywhere you have water and paths on your island probably wont get transferred over properly. because of this, after uploading your map, you'll have to manually adjust the height of anything under a water tile before clicking "add water" at the bottom left to have your map properly uploaded. thank you for understanding !!

step by step to use this feature:

  1. take a screenshot of your in-game map and transfer it to your computer (upload to twitter, use an sd card, etc) please make sure it is 1280 x 720
  2. select "load"
  3. select "load from image"
  4. upload your map
  5. make any fixes to your islands cliffs that got lost in the transfer
  6. click "add water"
  7. done!


THIS IS A SUPER EARLY BUILD!!! be warned.......... (imagine im saying this in a ghost voice) saving should be working but if you're using webgl i would test it out by making a few changes, saving, refreshing the page, and trying to load the save, cause if for some reason the saving doesnt work with your computer/browser i dont want you to do a ton of work only for it to not save properly!! windows and mac downloads are at the bottom of the page (you dont need to buy them you can just skip right to the download!!)

if youd like to support us and our continued efforts to make this even better, you can through the above link!! thank you so much to everyone for all the patience and the support so far!!!

since this is so fresh it might be broken/run badly for you, but i will do whatever i can to make sure as many people can run it so dont worry if its not working for you right now, i will do my best to fix it!!

we have a form you can fill out here for any problems/feedback you might have!! or you can just comment down below. would love to know of any performance issues, bugs, being able to do something you shouldn't be able to do, problems with saving/loading, and anything you think might just help make the planner better. you can also can find me on twitter here!! thanks again!!

current known issues:

  • performance issues!! if webgl is running real slow, you might need to download it (this only happens for some people,  specifically sometimes with chrome)
  • beaches and river mouths and such cant currently be properly set up, please use the big grid to properly line up your island!!
  • bridges and inclines can be placed literally anywhere
  • paths can be placed over water
  • sometimes when selecting a building/structure the cursor goes underground??
  • webgl killed my ambient occlusion so its kind of hard to see where cliffs start and end :(
  • theres definitely more
  • only god knows what will happen if you start messing with cliffs under an already placed building

not a complete list but right now my biggest priorities are:

  • any big performance problems or bugs that pop up now that i have let this out into the world
  • making some performance changes so i can let you guys zoom out alllll the way
  • trees, and rocks!!
  • select and move multiple tiles at once
  • additional incline/bridge/fence types!!
  • fixing up bridge/incline restrictions and any other in-game rules i might have missed (i trust your intuition to not make something impossible)
  • letting you edit beach shape to at least some extent
  • potentially letting you upload a picture and it generating a rough version of your island already prepared, this depends entirely on if i can get itchio to let me upload pictures and how well the in-game map reflects the island
  • definitely more but its 3am and i cant think

frequently asked questions!

  • are you planning on adding QR codes?

maybe further down the line!!

  • are you planning on adding furniture?

nope!! theres way too many! i do have plans of letting you make a placeholder cube with a set size/color/floating text above it to act as stand ins for furniture (and for future buildings if for whatever reason i can't keep working on this when new buildings get added)

  • can you port to mobile

maybe??? i dont know if i can legally put something like this on an official developer account

This was nice, thanks for making and sharing!

5 stars press b

I have a chromebook os, I've been trying to download it with linux for a week now, and it doesn't work.. if someone can help me, i would really appreciate it :( 

I am wondering if I can edit a planner I made after I had saved it?

Rating: 4.5 stars

I really like the way you did it, but the resources are limited.

You can improve by adding a few colours first.

Hey i was wondering if anyone had a save i can use for my island?


Maybe i'm not quite understanding what this tool is.
The issue I have with ACNH is that the animations of terraforming are so slow, it is painful to create cliffs and rivers on an island because of them. 

Does this tool allow me to create an island, and upload and APPLY the changes to my animal crossing island on my switch? Or, is this essentially a tool where you can design an island, then have to manually copy it tile-by-tile on to your island on your switch by following along as I play my switch?

Thanks for any clarification

this tool is purely for designing or planning an island that you intend to build separately on your Switch.

Only things i'd like to see are Other tree types(pine, coconut, and bamboo). and sand/beach area where red's boat goes


hi! I think it would be nice if the buildings (houses, plaza, etc.) could show up on the mini-map. And, maybe instead of adding every type of furniture, you could add the very, very basics. Like, a cube that's one/two blocks wide to represent many different furniture items or a chair that's one/two blocks wide. 

Hi!! i don't know if i'm missing something that I can do but it seems that the mac key controls are a little different, like for trackpad there's no command if I don't have left/right enabled on the trackpad, alt/enter on mac would be like command F but it took a minute to figure out lol, but yeah I think the biggest problem i'm having is just deleting cliffs because I'd have to use two fingers on my trackpad

it would be cool if you started adding some sets and some famous villagers, examples for sets are: simple items, wooden block items, log items, dreamy items etc. examples for famous villagers: marshal raymond ankha sherb etc

my save doesn't want to work anymore. I noticed however that its size was 401 Ko, while the saves that work are 400 Ko.

please, if you can help me...

Hellp I just downloaded the imac one and I cant figure out how to get out on the screen it says  alt enter to toggle fullscreen but when I press that nothing happened

I found the windowed thing to click so I can now control it

I'm having the same issue, but can't find the window thing to click that you mentioned? Help!

When you first open the app an opinion menu open up and you'll Find the list of screen resolution (The number x number list) right under that box is a little checkmark box with the word windowed next to it you click it(picture with windowed circled

Thank you!

no problem

Would be great if im able to get it.
tbh I tried MANYMANYMANY time (total 11 different times) some say "file moved or missing" or it's uploaded as a compressed folder that is empty. (unsure if it's unintentional programing or not.) if and when it DOES work. I go to click on the folder "Access Denied". when i go to properties, and enter the security tab. "requested information is either unavailable or cant be displayed". so far im getting frustrated as heck about this problem.

any help or explanation is welcomed.

Same thing happened to me

Thank you so much for making this! After getting used to the controls the tool is a lot of fun and it helped me brainstorm a couple of ideas I had for my island :D


I have a request and don’t know how hard it will be to do. But I have this app that I can take a minecraft world and export it as an STL or OBJ file that are used for 3d printing. If it’s possible to do the same thing with this app I would REALLY APPRECIATE IT!!! But I love this app and what it is able to do 


I would really like that as well, so it could be possible to reuse in a 3D software.

hey creator! I’ve seen alot of growth with your app. I hope everything is well, I don’t want to pry but I think making a way to extract the build we do into an obj or stl would be super cool for 3d modelers and printers. I would love that and I’ve heard other share the same thought. If you can that would be super cool!!

is there a way to change the size of the terrain brush? i have accessibility issues and only being able to place one at a time (even with click + drag) makes this really difficult (near impossible) to use. wish there was a way to raise/lower terrain in larger groups at once. (or maybe incorperate it with the ruler tool?)

Is this open source / do you have the source published somewhere?

I'm not a Unity guy, but I can help in the performance front.

I've downloaded the windows version but it doesn't seem to have any of the updated features. Is that only for the mac version at the moment?

Also, where would I get a .island file? From NHSE?

updated features should be in the windows version, if you check the left and theres a ruler and tree icon then its updated. there is an old windows build still up to download though so make sure youre not opening that one

.island files are made by the planner itself when saving!!

this is such a helpful app and TY for the update! 

that being said, a  lovely add-on would be if the grass on tier 2 and tier 3 were different shades so they would be easier to distinguish between when terraforming from the bird's eye view (perpendicular to the ground). Not sure if this has already been made a comment or anything and again thank you so much for this amazingly helpful tool.

On the side it says toggle cliff color mode. That should help.


YOOoo welcome back dev !! thanks for the update and have a good one :>

Hi hi, does anybody know where to find save files on mac? 

Came here to ask this^

I can only seem to raise the cliffs to tier 2 but not tier 3 is this a bug? 

Considering the update that's dropping November 5th, this is gonna help a lot to finalize my island. I've done very little terraforming to it because I straight up didn't know what I wanted to do. With Kappn coming back plus this, I can finally get my island finished almost a year later. 

TL;DR: This is awesome!!

Lovely, its super intuitive for an early build

okay I saved my file on the desktop version of this planner because I didn't think I would need to download it, but I can't for the life of me figure out where it went. Is /idbfs/islandplanner/saves/islandmanager.island even a thing?? I'm on windows and i've never seen idbfs in file explorer. I spent a lot of time creating my island using this planner so please any help on where the heck my saved file went would be appreciated

Hey! Try this address
 C:\Users\[YOUR USERNAME]\AppData\LocalLow

If that doesnt work, do the shortcut Win+R, then type %appdata%, then go up to the address bar and click 'AppData', click LocalLow, then 'bobacupcake' its most likey the first folder there :)
hope this helps :D

Thank you for the apps and it is really helpful! There's only one thing that need to be change, in this planner, I'm able to put fence and bridge in same box, but on my island, the fence and bridge is unable to put in the same box. I was forced to change my plan when the bridge was built. The size of bridge is 4x4. Hope that this setting can be changed and it will be more convenient on island planning.


Thank you for creating this app! I just started terraforming my island and this will be super useful.  There are too many posts to see if my question has been addressed. Does the zoom feature enable seeing the complete island at once? I can zoom large, which is great for working specific areas but I can't seem to zoom smaller to get the overall picture of my planning. Do you plan on future updates? I would gladly pay if affordable.  Your work and commitment of time is appreciated!  ~Gran~

It's a known issue that is listed above

Will you ever add a feature where you can upload a image of your island to make it a bit easier to map out how you want things to look?


hi! just wondering if there were any planned updates soon? I need some treeees hehe

If you want to submit this app on Google play store, list it as unofficial. Let me know if that works.

Do you have an apk for this app?

I have an ancient (its almost 12 years old) hp laptop with i think vista that runs this no problem but my new surface pro x cant? Ive extracted the files microsoft pops up 'find a different app, this isnt supported'. Im not finding anything online, just wondering if anyone has any suggestions?

I really like it! Helps me imagining my island :) It would be nice if the buildings on the minimap were also visible for better orientation ^^

For those who have problems at the beginning: the squares of the minimap are also present in AC:NH (in the map app). Maybe it helps :)

It´s already a cool tool.

But i wish some things to be added:

-trees, palmtrees, bamboo

-all kinds of flowers

-pumpkin-plants (all four colors)

-the airport

-the sea-bridge

-a custom-design-tool inside the path-tool, that opens a file-chooser-window to load 32x32 pixel png graphics from pc for placing as path on the ground

-a file-chooser-window to choose a custom location on the pc to save or load map-files
