What version is this from?

This just shows the screen, not the Tamagotchi! Anyhow, I found this cute pic of Tamagotchis mating and I wondered what version it was from.

I was thinking TamagoChu or Osu/Mesu.... Please help me soon because I've been debating what to get for my birthday and this looks epic! I thought of asking the member who had that avatar but they were last active in 2011.

It's the tamagotchi calculator. It's a very rare but cool tama

I found out it's actually an Arukotch.

Whoa! I've never seen that one before! I thought it was the calculator cause of the numbers.
