Planka looks like a really good option! I don’t suppose you know if the timer feature has some sort of report available - being able to export the time spent on each card?

Whoogle is what I’ve been using for a couple years. I found that you ideally need multiple IPs to query from though as it can quickly get rate limited by Google - if you perform a few searches in relative quick succession.

Do you know of any other’s like the murder mystery one?
