I used the app for some time, great job, but I suddenly noticed Hiya stopped responding I could not use it unless closed and opened it several times in a row, could not copy and paste the number, besides last time Hiya blocked an ability to call anyone, froze the keypad functionality even after the app was uninstalled. I had to restore my iPhone 6s. Sorry guys, I need my phone fully operational.
