Category: Updates

We have just released another update with some bugfixes, some improvements (bright mode for remote access) and a Serbian translation thanks to Marina Dorocki. You can find more details in the changelog below.

Changelog

Changes on Android and iOS

• Serbian translation
• Remote access stores settings (font size, layout) until the end of the browser session
• Remote access now has a bright mode (should help on low-contrast projectors)
• Fix error in distance calculation of location/GPS experiment. (Introduced in 1.1.0, please check any distance data generated in 1.1.0 or 1.1.1)
• Add 1/min to acceleration spectrum and magnetic spectrum to directly get RPM from engines

Changes on Android

• Save scroll position of experiment list after entering an experiment or adding/removing items

Changes on iOS

• Add gap between value and unit in value view elements to avoid confusing units
• Show optional dialogs and hints (save experiment locally, press arrow to start, etc.) after showing the Bluetooth scan dialog instead of not showing them at all
• Fix separators in experiment layouts

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

• 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.

While we are still working to finalize version 1.1.0, we just published 1.0.14 with another translation: Portuguese. Check out languages page for more information.

Actually, this update has been released on Android more than a week ago and should just be a quick language update on iOS as well. Unfortunately, Apple has rejected the update as they decided that the experiment "roll" might damage the phone. So we had to remove this experiment and resubmit the app. Therefore, the update got delayed.

Changelog

Changes on Android and iOS

• Portuguese translation.

Changes on iOS

• Fix flickering of audio scope.

Update 17.11.2018

There was a little error when compiling the new translations that introduced unfinished translations to the iOS version, which should not yet have been released (Turkish and Chinese to be specific). We have uploaded another version (1.0.15) for iOS, which should fix this as soon as it has passed the Apple review process.

With version 1.0.13 we have another minor translation update introducing Italian and Greek, created by Giovanni Organtini and Κωστής Χαλκιαδάκης (Costis Chalkiadakis). If you would like to help to translate phyphox into your language as well, check out our languages page for more information.

Changes on iOS

• Experiment "Roll" deactivated by Apple’s request.

Version 1.0.12 again brings new translations, Dutch and Russian, done by Ivo Janssens (with support from Evelien Urkens and Andreas Van den Bergh) and Alexander Nedilko, respectively. If you would like to help to translate phyphox into your language as well, check out our languages page for more information.

Also note, that we will happily share worksheets in any language. Since we can only provide the website in English and German, only those worksheets will be found directly in the experiment data base (like a fantastic new worksheet on pressure by Holger Jessen-Thiesen), but we will share any material in other languages on our languages page (like the first Dutch worksheet by Dirk Janssen). For more material we can also add a dedicated page for a specific language or add a link to an external collection.

Changelog

Changes on Android and iOS

• Dutch translation.
• Russian translation.
• Inelastic collision experiment hides invalid intervals.
• Translations are now also applied to units.

Changes on Android

• Fix lines connecting to first point when loading a previously saved state.

Changes on iOS

• Fix crash when value element has empty map tag.

With version 1.0.11 we introduce the first translations of phyphox, which are Czech and Polish, done by Karel Havlíček and Tomasz Greczyło respectively. If you would like to help to translate phyphox into your language as well, check out our languages page for more information.

Changelog

Changes on Android and iOS

• Czech translation.
• Polish translation.
• Introduced a new “language” entry to the info menu on the main screen.
