Welcome to MH Tracker
What is this?
This is a web application that allows you to track and trade crowns (as investigations) with other players in Monster Hunter Wilds. You can easily find players who have the crowns you are looking for and trade them for something you have in return.
Track
You can track your own crowns and see how many you have left for each monster. It's an easy toggle and gets saved to your account.

Trade
You can trade investigations with other players. As a means of helping each other, this app shows you what crowns others are missing as well. You can then contact them via a chat feature and offer them a trade or ask to join their investigation.

Crown Hunting Tips
Binoculars
Use the binoculars ingame to see the size of a monster. You'll have to be relatively close (around ~50m), but do note that you can also use them through walls and other obstructions.

Check, Rest, Repeat
You can ride through each region on your Seikret and quickly scan a monster on the go, swap to the next region till you reach the last one. Then, go to a tent, rest, and repeat the process. This way, the monsters and their respective crowns get rerolled.
Apex Predators and Weather
Apex predators only spawn during their respective region's "special weather" scenario. So it is recommended to always travel to one of the regions where you're missing a crown for an apex predator, swap the weather to the required one, and check through the maps again. This way, you'll have a better encounter rate with the apex predators.
The Arena
Currently, if you have a monster in the arena (the Hollow), its size is not actually set permanently, like in the other regions. This means, you can go into the arena, check the size of the monster, and if required, travel to Suja (loads quickly), and back, which rerolls the crown on the monster. This is a great way to quickly get a crown for that specific monster.
Investigations
Lastly, if you save an investigation (map, select the monster, start quest, save as investigation), the sizes of all monsters are saved. This means, you can share them with friends or other players, who might still need them. And that's what this app is for.
