⏰ In a nutshell,
If Alarmy is not set as an exception of downtime, Alarmy cannot ring with sound during downtime.
⏰ To elaborate,
Downtime is a feature in iPhone settings to limit your phone usage. During the downtime schedule you set, only apps you choose to allow are available. In other words, if you don't allow Alarmy to be available during downtime, Alarmy cannot make any sound or vibration.
Therefore, if you need Alarmy to ring during downtime, please set Alarmy as 'Always Allowed'.
- Go to Settings > Screen Time.
- Go to 'Always Allowed' and add Alarmy to 'Allowed Apps' list.
