Affix of sound mode and early notification into azan app

Azan is an application of muslim people To be aware(alert) when the prayer times coming,every prayer time comes the application will sound the call to prayer and every Muslim will go to the mosque or in clean area like room or somewhere to worship(pray).in point three in the upper corner of main view contains two imageview that is reloading data and settings.

Reloading data
will recover all data that has been set in app, in recovery it will take 2 minutes, the application will optimize all data and will run as before.this is the best way to overcome system errors.

Settings
Several icon in settings button among them Azan audio and azan calculation method.with Azan audio we could adjust
by applying full azan,takbeer or none
And with azan calculation method we could set the time of determination in azan,can be applied UMM al qura,egyptian general athority,kuwait etc

In utilization of app,I could find several Icon is not implemented inside.I wish in utilize the app could make completeness For any users.with deficient of some icons (features) can cause the application lack of the user, and this is a bad thing for the PO, so I as a client would give an Idea for PO to improve his app.

1.Sound mode
2.early notification

Sound mode is a icon(feature) which could be set sound settings, we can silence, vibrate, or ring a sound of azan, this can be applied to every(each)call to prayer.And sound mode in azan app we could prefer muazin who will proclaim the call to prayer.Sound mode is different with azan audio.I will show in mock up below.Early notification is a feature would alert a muslim a few minutes before azan time,This could be set in 5 minute,10 minute or 15 minute,when mode activated this will apply to each prayer time

There is several benefits would enhance grade of app for developer.

1.sound mode
For a muslim it's necessity to control a sound mode for each prayer times,
We can see this feature really helpful when follow meeting in noon,and in Islam there will be dhuhr time to prayer, like in mockup, then a Muslim can activated mode vibrate so the meeting uninterrupted,and in school room for a student this will not interfere with the teaching and learning process presented by the teacher.this feature different with azan audio,if activating a mode in azan audio it will apply to all prayer times and azan audio contains 3 mode,it is full azan, takbeer and none.

2.early notifications
This feature will notify a muslim that prayer times will coming in few minutes forward,it could be set 5,10,15 minute.
this allows a Muslim to prepare clothes, prayer rugs,etc before worship time coming,in islam to worship it's need all equipment immaculate(clean).

in my opinion,I sure the second feature above very useful to all Muslims, and make it possible for PO to implement as assessed really need.
