Question looking for app to link to phones together

[stuarthardee]

I have a Kyocera E6920 as a personal phone and IPhone 12 as a work phone I would like to find an app that links the phones together so that an alarm sounds on both phones if they are separated. I am basically trying to create a system as though I had Tile type devices attached to the phones. I have a tendency to lay something down and get caught up in something else and leave the thing I laid down behind. I am not interested in transferring information between the phones just a system to keep me from leaving one of them in some ones office. If anyone knows of such an app i would love to hear about it! Thank you!
