"It’s not just a game, it’s a quest to help scientists fight dementia!”

It sounds too good to be true but this really is a game, where simply by having loads of fun chasing creatures around magical seas and swamps, you can help to fight a disease that currently affects 45 million people worldwide.

In fact playing SEA HERO QUEST for just 2 minutes will generate the equivalent of 5 hours of lab-based research data.

Created by GLITCHERS, presented by Deutsche Telekom and supported by scientists from University College London and University of East Anglia and the lovely people at Alzheimer’s Research, SEA HERO QUEST is an epic culmination of science and gameplay that will change the way dementia research is done forever.

One of the first symptoms of dementia is loss of navigational skills. Doctors cannot differentiate between getting lost caused by disease and getting lost caused by natural ageing because a benchmark of “normal” does not exist.

Until now … because as you play, your navigational data is tracked anonymously, stored securely and combined with every other player from around the globe, to create the world’s largest crowd sourced data set benchmarking human spatial navigation. This incredible resource will eventually lead to the development of new diagnosis tools and treatments for dementia.

Navigate Arctic Rivers, Golden Shores, Mystic Marshes, Kano Reefs and High Roller storms, collect memories in your journal and chase magical creatures like Adorabella, Galleo and Octopoid. Collect as many starfish as possible and use them to customise your boat with a new lick of paint, a host of flags and much more!

Deutsche Telekom believes that life is for sharing, that’s why they are presenting SEA HERO QUEST – a game to help scientists fight dementia and work towards a future where memories are shared not lost before their time.

Join the Quest and be a real-life hero.

Sea Hero Quest does not access, store or submit any HealthKit related data. Sea Hero Quest uses ResearchKit to ask optional scientific questions for further helping the research.

Love it and support it


I really like this app and the game and hope I can support more scientists doing research like this. However, I found one thing a little bit disturbing and think it might effect the research. I hope it’s only me who find the sea monsters or what ever anime characters you make a little bit scary. Thus, I do hesitated to hit the final goals of each small challenge/chapter while playing ( like, go to the assembly point or what ever you call it, and take pic for monsters. They scare me and I would either click something too quick or too slow while I could have got the “ three stars”.) It’s not about hitting the goal of games or something but about research. I’m putting this thing out to see how many people would have the same feeling.

Great game, great idea.


Like other reviewers I have family members who have dementia and so when I saw this game and how it can help the research into this I was more than happy to give it a go.

What can I say, this is a great memory game. The levels are short enough to be able to just dip in and out of the game or it's easy to binge play it for several levels at a time.

If only all research was this much fun. Great job.

A great game with greater backing behind it,


The game is great and is fun with an interesting memory challenge built in.

I have a personal connection to the game, like a lot of people most likely do, my Grandad had Dementia and it was hard to see someone struggle in that way and I love all the backing behind the game, it’s reason and purpose.

Please pay to support further research!
