🎨 We've released "Minna no Jam," a free whiteboard app for elementary and junior high school teachers.
After Google's Jamboard ended at the end of 2024,
we've heard many voices saying, "We want an alternative that fits Japanese classrooms."
So, while listening to voices from teachers in the field, we created "Minna no Jam."
