Finally, after much more time than anticipated, the big update has been released: Version 1.1.0

This one includes interactive graphs (zooming, picking points, measuring differences between points), new graph types (multiple data sets, bar charts, color plots), experiment transfer via QR codes and an extremely versatile Bluetooth Low Energy interface.

We could write entire articles on each of these and there are so many more improvements and small details… Well, here is a video with a quick overview of the big ones.

If this is not yet enough for you, here is the full changelog:

Changelog

Changes on Android and iOS

• Phyphox is licenced under the GNU General Public Licence from this version onwards
• Bluetooth Low Energy support
• Bluetooth Experiments included: Generic heart rate sensor, generic HID mouse, PocketLab One, PocketLab Voyager, Sensirion Smart Humigadget, Texas Instruments SensorTag CC1350/CC2650
• Interactive graphs (zooming, picking points, linear fit)
• New experiment: Applause meter
• Multi-line plots
• Bar charts
• Color plots (used in spectrum experiments)
• Open experiments from zip files or QR codes
• Raw sensor experiments now feature a multi-line version
• New languages: Chinese (simplified script), French, Vietnamese
• Acoustic stopwatch has a new “many” tab , which allows measuring of an unlimited number of events, giving each interval and calculating the rate (Hz or bpm) and average interval of all events
• Improvements to make the sonar more reliable
• Performance optimizations for several experiments
• Distance from start info for GPS-Experiment
• Inclination experiment now features several different reference systems
• Removed the libraries jquery and flot from the remote interface, which now uses chart.js instead
• Remote interface now starts with a font-size recommended by the browser and allows changing the font size
• Picking data points in the remote interface
• The remote interface allows to show a single graph filling the full screen
• Remote interface now communicates through a queue to avoid missed requests by the single-threaded webserver on the phone
• Introduced a default color palette, which is used for coloring multiple graphs and can be referenced to by using names (red, blue, etc.) instead of RGB-values
• Experiment configurations can be loaded directly from BLE devices
• New device info report from menu on main screen
• Add color to special categories (saved states and simple custom experiments)
• Allow external experiments to define icon and category colors
• Allow renaming of saved states
• Use experiment title as default file name when exporting data, saved states or screenshots
• Show state title in experiment info
• Add hint to start button and add logic to hint bubbles, so they only show up until the user has used the specific function a few times
• Fix: Wrong scaling of data in Doppler experiment due to outlying points
• Fix: Consider available precision in remote interface to avoid retrieving the same value multiple times
• Improve magnetic ruler for longer measurements
• Fix inelastic collision experiment only working after pressing “reset”
• Disable export and explain it to the user if an experiment configuration does not define an export

Changes on Android

• Fix calculation of GPS height above geoid (MSL) if non-GPS satellite systems (GLONASs) are used
• Vertical accuracy in GPS data if supported by some Android 8+ devices
• Support temperature and humidity sensors
• Support vendor-specific sensors by guessing their function by name
• Improved performance by using native code for some operations
• Improved Fourier transform performance by using the FFTW library
• Allow screen rotation during measurement (now consistent with iOS)
• Prevent adding identical experiments multiple times
• Add notice when no address for the remote access is available
• GPS now also uses network data by default and offers to force GPS only in the menu
• Fix: Crash on malformed icon data
• Fix: Sort categories case-insensitive
• Fix loading experiments from URLs without query strings
• Fix: Result response from webserver used broken JSON format.
• Limit state title length

Changes on iOS

• Complete rewrite of experiment parser. Much faster and much more stable when loading external experiments with errors.
• Buffer rewritten. This should fix previous crashes in long-term measurements due to a race condition when accessing the buffers.
• Respect save area guides to avoid drawing the UI in areas used by system buttons or the notch (iPhone X and similar)
• Fix: Missing parts of a translation fall back to English defaults
• Fix: Pick experiment language according to app language and avoid using unreleased languages already present in the experiment definition files
• Fix: Re-saving states crashes the app
• Fix: Power function fails for negative exponents

File format (version 1.7)

• New graph types and multiple graphs
• New Bluetooth Low Energy definitions
• New “formula” analysis module
• New “reduce” analysis module
• New “map” analysis module
• New attribute to enable analysis optimization (only re-run modules if their inputs have changed)
• Label and unit can (and should) be separated for graphs to allow giving the right unit when reading a single data point
• Colors can be names instead of RGB hex values
• Value and info elements may now be colored
• Temperature and humidity sensor types

Thanks to Wakana Okita and Keisuke Takashima phyphox now speaks Japanese. More information about our voluntary translators can be found on our languages page.

Changelog

Changes on Android and iOS

• Japanese translation.

Changes on Android

• Fix: The experiment “light” was not available if the list of preferred languages in Android did not support any language supported by phyphox.
