Honestly, I built this app for myself since I lost many professional and personal connections. It started with just coming across a news about Replit that got 400m investment so I decided to build an iOS app without coding. It's name is Ping Pals https://apps.apple.com/tr/app/ping-pals/id6770330997

The idea is extremely simple, just add your pals that you do not want to break the relation in three levels: close, inner and distant pals. Then app allocates a bar with your pals for 30, 60 and 180 days. Each day it decreases by one, and you can check your pals' health in the dashboard. When you sync with your pals, you can restore the pals' bar manually.

It is free, local, no account needed, and notifies you when pals are getting into the danger zone (<1/3 ). As a side feature, you can add the custom events with your pal, such as a birthday.

Feel free to use and give a comment here. Future work is adding more personalized features and interactions with your pals.
