ChronosBot is a personal project I started with two purposes in mind:
The premise is very simple: basically you set up an allowance for each child in the household and then use Alexa, Google Home or chat bots to withdraw time whenever it's used. You can say things like "Alexa, ask ChronosBot to withdraw 20 minutes from Jenny's account" or "Alexa, ask ChronosBot for the balances". You can even give rewards, charge penalties and pay for chores with screentime.
I'd originally intended to keep it private but decided to make it public after a number of friends and associates told me they wanted to use it in their households. Never-the-less, this remains both a hobby and a development experiment. I'm not investing time or energy in prettifying it, so manage your expectations accordingly. I am interested in construcive feedback and feature requests, though - please click here to send me an email with your comments.
