There's a Window's app called "APK Easy Tool" Thats really great for both decompiling and recompiling. Also there's an Android App called "APK Editor Pro" which I use 75% of the time depending on what I'm decompiling. Of course you have what I'd like to call the Grandfather of them both "Android Studio" Which can get complex and is definitely in my opinion overkill if your just rebranding. I hope that helps.
