I'm always losing my phone

Apple Watch has a button that will make your phone sound an alarm so you can find it. Swipe up from the bottom and there’s a button you can tap that makes the alert go off.
Google assistant will ring it at full volume if you ask it to. You could also use ifttt or tasker, this probably doesn't need to be an app.
If you have amazon echo linked to your phone you can ask amazon to locate your phone
In my POV :This won't work cuz it has to have access of location and certain permission allowed all time..and people won't do that..cu they care abt their privacy..
