Weekly Release Notes - 2025-12-09

Hello everyone,

Let’s take a moment, or maybe a bit longer, to explore what’s new and discover how these updates can help you work more efficiently in Avicenna.


:rocket: New Features

Fitbit Food Summary

We added support for the Fitbit Food Summary metric to track daily nutrition intake, including calories, carbohydrates, fat, protein, fiber, sodium, and water. For more details, see our Reference.


:sparkles: Improvements

Survey PDF Export

Surveys can now be exported as PDFs with all configured languages included. Each localization starts on a new page with a clear header, and all answer options for choice-based questions are listed. This ensures organized, easy-to-review survey documentation. For more details, see our Reference.

JSON File Support

File questions in surveys now better support JSON uploads. Previously, some valid JSON files were incorrectly rejected because the system could not recognize them as JSON files.
We’ve fixed this issue so that all valid JSON files are now properly accepted, regardless of their size or structure. Invalid files will still be rejected to ensure data quality.

Garmin Unit ID

The Garmin Unit ID is now visible in the scanned device list on Android, just like on iOS. This ID helps users reliably identify their own watch during pairing and can be found on the device under Settings > About.


:lady_beetle: Bug Fixes

Warning for Untranslated Answer Options

We fixed an issue where the survey editor failed to display warnings when all answers for a choice-based question were empty in a translation other than the Base language. This caused untranslated answers to go unnoticed.

Survey Submission

We resolved an issue where, in rare cases, submitting a survey on iOS caused the app to crash, even though the responses were successfully recorded. This ensures a smoother experience and prevents unexpected app closures after survey submission.

Survey Post-Submission Message

We addressed an issue where the message shown after submitting a survey, informing users that they have other activities, did not appear. It now works as expected, ensuring users are properly notified about any ongoing activities after completing a survey.

Onboarding Alert Stability

We fixed an issue in the iOS app where the app could freeze while loading onboarding alerts for active studies. These alerts are now processed in the background, making the home screen load faster and keeping the app responsive for all users.

Calendar Question Filters

We resolved an issue on the researcher dashboard where filter conditions based on survey calendar questions didn’t allow the researchers to enter date/time values. Condition values can be entered as expected, and switching between single and interval types preserves previously entered values.

Carry Forward Toggle

We addressed an issue where disabling the Carry Forward toggle in single-answer questions blocked adding new options. You can now add answer options correctly after turning off Carry Forward.

Participation Period Update

We fixed an issue where changing the participation period caused an “Internal Server Error”. Updates to the participation period are now applied successfully.

Font Scaling

We resolved an issue in the Android app where text size didn’t follow the device’s settings. The app now respects system font scale, adjusting font sizes correctly when users change text size.

SensorKit Data Source Initialization

We addressed an issue where all SensorKit data sources were initialized by default. SensorKit now only starts the sources configured for the study, and removing a source in the dashboard prevents it from running on the device. This avoids unnecessary high-frequency data collection and improves performance and battery life.

Corrupted Data Files

We fixed an issue in the Android app where, in rare cases, corrupted data files were created and uploaded. This update fixes the root cause, preventing such files and ensuring data is processed successfully.
