It works if done right
At first didn’t work but later I played with the notification settings and it started working. Remember, this is technically a notification app, not alarm. You need to give it permission somewhere in the settings. Also, it works best when the phone screen is locked. When you are using the phone for videos etc. it is muffled. I found it very useful. Much better than alarms that keep going. This one will repeat what you wrote about 8 times and then stop. I was able to make it loud enough to hear while driving. There could be more updates on it but remember this is still the Beta version. If there is enough interest they might invest in an upgrade.
