So regret that I have purchased this app from this developer

The time lag is quite problematic as its not responsive. What is so funny about this developer is that when they update their app (enabling the usb cable function), they dont allow the version 2 users to update the app. The users are required to purchase the new version 3. Isnt it funny? No more deal with you Mr. Developer!
