Bolt Reader®
Bolt tension reader
Free · Designed for iPad. Not verified for macOS.
Thanks to the innovative undertaking of creating the Bolt Reader® application, users have constant access to information on bolt tension. Information is presented in the form of bar graphs, which allows you to quickly spot screws that require attention. This application is specifically designed for Bolt-Cap Module devices produced by Transmission Dynamics.

2.0 22/02/2024
Improved reliability of export of device samples to CSV files.
1.9.5 23/08/2022
More detailed firmware information for BCM v2 devices running recent firmware
1.9.4 01/07/2022
* Correct handling of non-connectable Bluetooth Low Energy adverts (ensures compatibility with future device firmware upgrades for Bolt-Cap Modules)
1.9.3 06/04/2022
* Visual overhaul of the Settings tab and multiple small improvements in app appearance.
* Selected devices tab can now be populated quickly with all items from 'All devices' tab.
* Fixed a bug where the buttons in navigation bar would not be updated on changing the active tab (occurring only on iOS 14).
1.9.2 18/02/2022
* If persistent data storage is enabled in app settings, users can select the time range for export when exporting measurements to CSV file.
* App layout no longer breaks when tension significantly exceeds the maximum value (which typically happens due to BCM miscalibration).
* Changes to numeric fields in configuration editor for BCM v2 devices are reflected in error messages immediately rather than when field loses focus.
* App will warn user who is editing BCM device configuration if that device configuration is changed by some other user in the meantime.
* Device measurement graphs are paged if the number of measurements is too high to display on one graph without negatively impacting app performance.
* Fixed a bug that resulted in app maintaining connection to BCM longer than necessary on cancellation of device configuration change and on error in real-time monitoring mode.
1.9.1 11/02/2022
* Measurements can be saved in persistent memory and preserved between application restarts for export to CSV file.
* Application layout no longer breaks when Button Shapes are enabled in iOS accessibility settings.
* Improved compatibility with BCM v2 devices.
* Multiple small issues fixed.
1.9.0 04/02/2022
Fixed a bug where duplicate entries were sometimes occurring in the exported CSV files.
1.8.6 19/01/2022
Fixed the problem that was making the app crash on iOS 14.
1.8.5 22/12/2021
* Improved device connection reliability
* Multiple bugfixes
* Typos in the Information tab have been corrected at last
1.8.4 16/12/2021
* Minor improvements to configuration screen for second generation BCM devices (BCM v2).
* Fixed a bug where the app would crash on exporting data from multiple selected devices if an uncalibrated BCM v2 device happened to be among them.
1.8.3 30/11/2021
* BCM V2 devices firmware can now be updated using the app
* Improved app appearance in landscape mode on screens with rounded corners
1.8.2 29/10/2021

* Better support for new generation of BCM devices (BCM V2)
1.8.1 26/10/2021
* Support for new generation of BCM devices (BCM V2)
* Streamlined device details screen

* Fixed minor glitches occurring on iOS 15
* Multiple performance improvements
1.8.0 21/10/2021
Basic version of the application is now available for free with some limitations that can be removed by purchasing the full version.
It is finally possible to reconfigure multiple devices at once, and to add a device to 'Selected devices' by clicking a button in device details screen instead of waving a magnet over the device (useful if the device/bolt is located in some inaccessible place).
The maximum period of time presented in the graphs can now be configured in the 'Settings' tab.
1.7.0 24/08/2021
Fixed a bug where it was not possible to save BCM configuration changes if the BCM device was running firmware version 9
1.6.1 02/07/2021
Minor improvements, updates and bug fixes.
