Does anyone know of a self hosted service that does kids sticker charts? Here’s what I had in mind:

Kid interface:

• Tablet with browser open, shows a column per kid with name at the top plus how many stickers are available
• Kid can click the + button and choose a sticker to add to their sticker chart (unless they have run out)

Adult interface:

• Log in
• Ability to add to the available stickers for a child

Basically, kid does something good, adult adds an available sticker for the kid, kid gets to choose the sicker and see it on the sticker chart.

Anyone got any suggestions for anything that even remotely resembles what I’m looking for?
