# Measurements
Open Measurements in the bottom navigation to review measurements stored on the phone. It includes pending and uploaded Project measurements as well as local Quick Measurements.
# Measurement status
- A cloud with a check indicates that a Project measurement was uploaded.
- A pending Project measurement remains on the phone until it is uploaded or deleted.
- Quick Measurement entries remain local and are not uploaded to a Project, even if the list shows a pending-style cloud icon.
# Main actions
- New Measurement resumes a selected Project measurement workflow or opens My Projects to choose a Project.
- Upload All uploads all eligible pending Project measurements when network settings allow it.
- Select All selects measurements for bulk actions.
- More options provides list-management actions such as selecting pending measurements or cleaning up uploaded local copies.
# Review a measurement
Select a measurement to open its warnings, protocol results, calculated values, and traces. A pending Project measurement can also provide actions for adding a note, taking a picture, uploading, or deleting the local measurement.
The Measurement Result card keeps the main values together. Tap More values to expand additional calculated results and tap it again to collapse them. The example below is a saved Photosynthesis RIDES 2.1 Project reading.
The app processes each reading using the macro attached to its protocol, matched by protocol ID. Different protocols can return different values and traces. If the protocol or macro is unavailable, the app identifies the displayed data as raw measurement data.
# View traces
Tap View traces to expand the available graphs. RIDES can provide processed PAM fluorescence, P700 DIRK, PSI absorbance, and ECS traces. Tap View traces again to collapse them. Raw fallback traces are labeled (raw); invalid calculated traces show a notice rather than a substitute graph.
# Raw Data
Tap Raw Data to open the complete stored measurement JSON. Select text or use Copy to copy the full JSON, then use the circular X at the top right to close the modal. This view does not edit the measurement.
Project-question answers and raw measurement data cannot be changed after collection. Notes or photos can be added only while the measurement remains editable locally.
# Upload measurements
Use Upload All to upload all pending Project measurements, or open/select an individual pending measurement and use the upload action. The WiFi only and Auto upload options in Settings control when uploads are attempted.
Field collection
Review the Measurements screen before leaving the collection location. Confirm that expected measurements are present, then upload them when a reliable connection is available.
Compare the number of pending measurements with the field log or planned sample count. Investigate missing, duplicate, mislabeled, or warning-bearing measurements while the sample and collection context are still available. Do not delete local pending measurements until their uploaded records have been confirmed in the Project data view.
For guidance on reviewing warnings and flagging records, see Data Issues and Flag Measurements. A statistical outlier is not by itself evidence of a bad measurement; retain or flag data according to the study's documented quality-control rules.
# Troubleshooting uploads
- Confirm that the phone is online.
- If WiFi only is enabled, connect to WiFi or temporarily change the setting.
- Confirm that the measurement is a Project measurement rather than a Quick Measurement.
- Restart the app and try the individual upload action.
- Do not uninstall the app while pending measurements remain on the phone.
- If measurements still do not upload, use Send Debug and contact support@photosynq.org before clearing app data.
