Version 1.1.1 with bugfixes

We heave just released version 1.1.1 with some important bugfixes. Please, if you still find any errors in phyphox, let us know via email (staacks@physik.rwth-aachen.de), via our forums or via the tracker on github.

Changelog

  • Fix crash in data picker

Changes on iOS

  • Fix: Elevator experiment not working due to an error in the new formula parser
  • Fix: Crash of color plot (mostly when starting the sonar experiment)

The big update has arrived: phyphox 1.1.0

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:

Version 1.0.16: Japanese translation

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.

Version 1.0.14: Portuguese translation

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.

Version 1.0.13: Italian and Greek translation

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.

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

Version 1.0.12: Dutch and Russian translation

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.

Version 1.0.11: Czech and Polish translations for phyphox

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.
  • Fix: Flickering in motion stopwatch.

Changes on Android

  • Update to file format 1.6 and support audio sample rate output. (Which has been introduced as a hotfix to iOS previously.)

Version 1.0.10 (hotfix for iOS)

If you are using an iOS device (specifically an iPhone older than the iPhone 6s or most iPads) and tried our latest update, you will quite certainly have encountered the error “rate mismatch”. Sorry about that, we have just released version 1.0.10, which fixes this. (Since this only fixes the iOS issue, there will be no 1.0.10 on Android.)

If you are working with your own phyphox experiments, the following details might be relevant to you:

The problem here is, that there is no guaranteed way to force a certain audio sample rate. You can set a preference, but the system might chose to ignore this (for example when using AirPlay, which forces 44,1 kHz). Since many experiments require the exact data rate for their calculations, we inserted a check, which tests if we actually got the correct rate. Turns out that this resulted in the error on all older devices which natively run at 44,1 kHz because a) we checked to early and the desired rate might still be set correctly and b) there are several more scenarios which prevent switching to a specific rate. Therefore we now allow that the system sets a different rate and modified our file format, so that the experiments can get the actual sample rate and use it for their calculations.

This means, that at the moment the file format in iOS supports this new output while the Android version does not. We will fix this with the next update soon, but if you rely on the exact sample rate for your own experiment, please let me know, so I can help to get this right now.

Version 1.0.9 (minor bugfixes)

Version 1.0.9 was just published to address a range of minor problems (we are still working on the big update with Bluetooth and interactive Graphs). This most important fixes of this update address crashes related to the remote access on iOS. Thanks to everybody who reported these bugs.

Changelog

Changes on Android and iOS

  • Location (GPS) experiment now calculates the distance travelled.
  • Pendulum experiment shows a genreic results page first.
  • Minor optimizations of remote access communication.
  • Minor optimizations of text in experiments.

  • Fix: Crash when using the remote access in hotspot mode.
  • Fix: Crash when saving a saved state a second time.
  • Fix: Crash when activating remote access while port 80 is already in use.
