SubQuest
A little detour from your everyday.
Things that would never have happened, brought into your day. Ride your usual line to the last stop. Walk into a little shop you have never tried. SubQuest sends these small detours as "Quests" — and the stage is the real world, not the app.
How it works
Accept, head out, and keep it as a card.
- Pick a Quest you want to try
- The time limit starts the moment you accept
- Take on the Quest out in the real world
- When you finish, add a photo and a few words
- Your own Memory Card is saved to your Collection
Features
Memory Card
Your photo and thoughts become a card, just as they were. A record of that moment, never remade.
Collection
Look back on your cards by Pack, or flip through them as an album.
Quest Pack
Themed Packs, like Quests that shine on rainy days or ones that feel nostalgic.
Friends & Party Quest
Share Memories with friends and take on Party Quests together. Nothing is shown to strangers.
At your own pace
No rankings. No "right answer" and no proof needed. Enjoy it your way.
