Good day to all.
I have an application that has been working for a long time and while everything was working fine, but now it began to slow down and I stumble in the feedback of a complaint from a client, but I urgently need to update it or make a new one as similar as possible and quickly can someone help me with this?
You should mod your application from time to time, then there would be no problems. But I think you can fix this situation too. You need professional guys who know a lot about app development. I see that you have already been recommended a website where you can find help. That's why I love forums! It's always easy to find what you need here.
