Vastly improved download speed of the Worldwide Turntable database

Performance enhancements - the RPM World DB is now fetched at a lower to improve the  performance for everyone.
The RPM World TT DB now has over 8,100 entries and has become an important resource for all Turntable enthusiasts.

Due to popular demand the World TT Database is now searchable by make and model. There are now nearly 5000 uploads of turntable accuracy data and ratings from turntable enthusiasts all around the world.

Updated settings screen with more help.
Added additional onboarding help screens.

For those testing old 16rpm turntables the accuracy results have been corrected to calculate against 16 2/3 rpm, oops!

World DB Stats now shows Top 50 Makes & Models
iOS13 Ready

minor bug fix

small bug fix

The World TT DB is now cached locally on the device so it doesn't have to be downloaded every time.
New DB Stats Screen showing Top Makes and Models in the World TT Database.

The World Database may now be sorted by Accuracy, Wow/Flutter, Rating, or grouped by Make/Model.
When uploading to the World Turntable Database you may now delete or replace existing submissions as required.
The list of Turntable Makes is now searchable to make it easier to upload your recordings.

Bug fix affecting some rpm accuracy figures stored in MyHistory and WorldDB.
The World RPM Turntable Performance Database is up and running, accepting submissions from RPM users worldwide to build the ultimate resource for researching the most accurate turntables out there.

Show continuous rpm display even if turntable is very inaccurate.

You can now save your rpm tests to the history log for viewing and sharing later.

Fixed an issue where some handsets with an unreliable compass will show zero rpm.
Option to hide 'Uncalibrated?' Button.
Fix issue where centre circle didn't turn green unless 360 trace was on.
New icon to distinguish it from the free to try version.

If you own a turntable RPM is a must have.
Calibration Mode is here!
The RPM realtime display is reliant on the iPhones gyroscope accuracy, if you suspect yours isn't quite right then you can now use Calibration Mode to auto test and then apply any necessary correction in real time.
This auto calibration uses the compass to count the turntable revolutions, if you have an older iPhone (iPhone 6 or older) then this may be unreliable, in this case you can still add your own multiplier if you have done an independent calibration.
Extensive testing means we're now confident that using RPM can help you setup your turntable to be within 0.1% of its target RPM, assuming your turntable can be adjusted and is itself stable within that tolerance of course.
Update ensures you can correctly enter your own calibration value in any Region.

Improved graphing efficiency to remove lag reported by some users.

Now displays the actual wow/flutter accuracy figure as the max % deviation from the average rpm of the turntable, the real time graphing of the accuracy variation over time is still there of course.
Improve positioning of vertical lines which indicate each revolution.
Display target RPM on centre line of graph.

Bug fix, wasn't auto detecting 16,45,& 78 rpm speeds.
