ConKarma lets you stay close to your grandkids without downloading an app, learning a new interface, or remembering a password. Your son or daughter invites you from their Cell, and once a week you get an email digest with a signed link — click it and you see a nicely rendered page of highlights from the week in any browser, no login. Once a week the kids also ask you a question, like "Grandpa, what was YOUR 8th birthday like?", and you can record an audio answer right there in the email.
It's read-only and private: the links are single-use and expire in 14 days, the audio you record goes only into the kids' archive, and there's no account, no tracking, and no marketing. The digest arrives Sunday morning with no streak nags or guilt reminders, and if you ever want out, you reply STOP and the parent is notified to remove you.
