Hi Guys, I think some people from SMD might have posted here about this already. Im the one behind the app and proud to get something out there finally Android app for box tuning is finally here...FREE... This is Beta still and can still be buggy. I am constantly working on updates and fixes and new features though. The app is for android 2.1 - 15+ , so hard to test when developing. Currently the app allows to calculate box specs and there is a total resistance calculator. The app can be found by searching "box tune calculator" and can also be viewed here My app If you have any requests of what features you want, please let me know and i can add them. if there are any crashes i get reports and ill put out a fix ASAP, also you can comment here. Features to come: Cut sheet with images speaker wiring diagrams and improved Ohm calculator wire voltage drop calculator and more.... Would really appreciate it if you support me Thanks Guys Enjoy the app Also im working on the iphone app as i type this, so expect to see something soon for iphone.
