Here's the mockup I made:

Have you ever texted someone that you'll be over in 15 minutes, and then proceeded to lose track of time, arriving embarrassingly late?

Well, with the Soft Timer, you can forget being late. Basically, every time you mention a short period of time, (<45 minutes) a Soft Timer is set and can be seen on your iPhone home screen. When the timer counts down, you get a small notification in the form of a gentle vibration!

The notification itself is designed to be soft, so it doesn't cause anxiety but keeps you organized and on time!

If you'd like to see if there's any demand for this, I made these posts /r/LightBulb and /r/Apple and people really seem to want this kind of feature!
