Hello, I'm a Japanese developer. Let me introduce myself shortly. I’m the kind of person who is very forgetful. I’ve been scolded by my wife more than once, and my boss has also asked me things like "Didn’t you set a reminder for that?" In addition, I'm so careless and always miss notifications So, I used to use an alarm app because it's noticeable. But I also forget to set an alarm many times. That’s why I built an alarm for a specific date and time.
