I wish I could give zero stars!
Time settings don’t work as they should AT ALL and it gives no notification, chime, or anything to let you know timer is at zero. Don’t waste your money.
Response from developer
We have now added several notification options. :) We intentionally chose not to include them at first, as frequent reminders could psychologically reinforce the habit of smoking. The goal of our app is to gradually extend the time between cigarettes in small increments, helping users reduce the habit naturally until they eventually stop thinking about smoking altogether. However, since several users specifically requested notification features, we have now added them as optional settings. :)
