Been using the app on my iphone pro 14 very reliably. But would like to free the phone from this duty and buy a used older iphone for the job while I keep the 14 as a camera for the shows I am making and as a backup should the main phone craps out. What would be the limit,on a older iphone, regarding CPU, ram, DAC quality etc to reliably ran the app as it is plus when any big update rolls out?
Thank you everyone for your help in advance!
