Update the app to make it work with ios 11 – Localphone: Local Numbers - cheap international calls Review

Been using this app for at least 5 years . Got addicted to use this for international calling. But this app stopped working after the apple’s latest software update. Tried to contact the customer care, but nothing happened. They said they are working on it, but it's been almost a month now and still the same..Please update it so that I ( and many more like me) can use the app
