So, I respect the entrepeneurship and technical skills to make this. Well done!
That being said, this is insane.
Maintaining your social network is a skill, just like being able to swim, doing math, being able to hold a good conversation, being able to code or cook or do your taxes.
The "promise" and "illusion" of silicon valley is that all problems (including and maybe even especially social ones) can be solved with technology. This is not true.
Having to use your brain to think about things is definitely painful. It also has incredibly good long-term effects -- and also negative short-term effects because it costs energy. It's similar to eating well, regularly exercising and other aspects of taking care of yourself.
Making sure you can remember to think about other people is not a problem -- it's a REALLY valuable skill that is gradually disappearing.
The problem is not remembering other people, it's contacting them. One always has a thousand excuses to not do the right thing. By gamifying it, and setting reminders, it gives a nudge in the right direction.
It's not different to setting reminders to go to the gym, take your medicine, or any other thing you should do regularly.
And by using this clutch you can train your social muscles so you end up not needing it.
I've used something similar in the past, setting up reminders during the day to keep in contact with someone, using them enough so now I can keep in touch with them without needing the reminders (I no longer have them set up).
For some people there are "basic" things that are hard, these kind of tools are for them.
Basically you're telling people to not be ADHD. Well thanks but it doesn't work like that. I wish. Reminders definitely help especially because our minds are so bad at prioritising. Tools like this can definitely help.
The page specifically mentions ADHD and the design is also a bit too quirky for neurotypicals anyway.
