This app quickly eliminates the unconscious anxiety Japanese people feel every morning before heading out: "Is everything okay today?"

"Did You Know?" is not an app to prevent you from forgetting something. It's an app that provides the reassurance of knowing you've checked.

■ Recommended for
・People who rush around every morning and worry about forgetting something
・People who worry about "did I have that?" before leaving
・People who have ever been in trouble because they forgot something
・Working adults, sales professionals, and field workers
