A series on curious apps also seems like it could help with brainstorming new apps, this app however as with all artistic social commentary will most likely not gain much traction amongst the people who could benefit from this.
and there is also the flip side.
I can see this app being misused and have an influx of actual people intending to die together. Then you have the ridiculous situation where uppity parents blame Pokemon for their child's suicide instead of owning up to being pathetic human beings or that the person just needed to get out. But that is just my 2 cents. Anyone want to play blue whale but with voodoo dolls instead?
The app prevents people from using it unless their phone is low on power. And even then - conversations are short. There's no shortage of places and apps for the depressed and suicidal, and I don't see how this one (paid app!) would attract that audience.
edit: if you're looking to brainstorm about apps, find me on discord. I still kinda work in mobile app marketing.
