Experience
Tube, a Minimalist YouTube Client
https://github.com/madelinecameron/tubeTube was a minimalist YouTube client, designed to be strip away as much of the cruft as possible so the user could focus on the video itself. After the user finished watching a video, they were navigated back to the extremely minimal homepage rather than having the next video auto-played.
The client was designed to help people who struggle with internet addiction or focus to better focus, rather than forcing them to get rid of YouTube entirely since many use YouTube for streaming music while they work.
Shut down in Aug 2020 due to Google revoking the API key, it ran from 2018 until Google's crackdown on API usage.

PhonePrivacy
PhonePrivacy is a service that enables a user to have multiple phone numbers, much like you can have multiple email addresses.
The underlying belief is that we segment our lives in emails (or at least should), and we should be able to segment our phones as well.
I give my dentist the same phone number as I do to a loved one, giving both equal access to my phone. Both should have differing access to my attention.
Also, PhonePrivacy is working to help block robocalls before they reach the user's phone.
