#3 Ship with long loud alarm as default

[Pander]

Offer to force playing loud alert that is shipped with this app. For example https://www.freesound.org/people/guitarguy1985/sounds/57808/ would be good. Some phones have very short or soft sounds configured for SMS alert that won't help you find your phone. Also it is possible that a phone, for some reason, does not have any sound files for alerts, hence the once shipped with the phone is needed. Please enable playing this long loud sound by default and give the user teh option to switch it to the default alarm (which is not recommended).
