This app has a lot of potential. Instead of just a community app, they could add the following:
1. Interactive map
- Where we can track stuff (including but not limited to geniemon spawn locations, mining items, fishing spots, collection items, quests, waypoints, etc), has the option to connect your account, automatically mark as complete what you've already unlocked or finished, and with timers for collectibles.
2. Character progression
- Easily check each of your character's levels, wedges, weapons, introns, and whatnot with the option to export them into an image file or share them here.
3. Code redemption
- Easier code redemption through the app.
4. Game details
- Wiki stuff like character introduction, lore, voicelines, and whatnot.
5. Achievement tracker
- What achievements you're still missing and how to get them.
Personal preference:
- Dark mode
- Website/PC version: Honestly, I prefer these types of community apps as websites because I'm more of a PC person than mobile when it comes to social media but I wouldn't mind if they'll introduce a PC app.
What other features would you like to see in this app in the future?
