• Custom session (Pro): you can now compare measurements of different lengths (for example, a 5-min T1 and a 2-min T2) and still get the full analysis, with a note in the technical report. • When the full analysis is not available, the app tells you why and which measurement caused it. • Import recordings (Pro): add, reorder and remove measurements in the sequence. • Fixes.

• Custom session (Pro): you can now add, reorder and remove measurements during the session, without going back to the start. • Better with large text: the Terms screen and buttons adapt to the device text size. • Fixes.

• New Import recordings mode (Pro): use RR interval files recorded in another program. The app calculates and saves the result with the actual recording date, and the PDF shows the source. • 4x6 Breathing in the task library (Pro): breathe in for 4 seconds and out for 6. • Adjustments to the recording modes and fixes.

• New recording modes (Pro), with on-screen guidance, a warning when the signal is weak, and a PDF report. • Receptive fields in the Custom session (Pro): mark the start and end of each stimulus; the app compares the 15 s before with the time during (HR and RMSSD change) and suggests a response for you to confirm. • Technical report: choose to include the recordings and custom sessions, each with its own date. • Bluetooth: clearer error messages and a shortcut to Settings when permission was denied. • The HR curve shows the last minute of the recording. • App Store: the listing now shows Portuguese, English and Spanish; permission prompts in all three languages. • Translation and navigation fixes.

• Heart rate curve: during each recording, a beat-to-beat curve replaces the bars; at the end you see the whole recording, and the curve is saved with the result. • Free length: besides 2, 3, 5 and 10 min, choose Free — the first recording sets the length of the next ones. • Custom session (Pro): build your own sequence of rest, activity and recovery, each recording with its own length and position, and save it as a custom setup to use again. Technical PDF report with your note. • Changing devices: importing a backup now also brings back your professional profile, and can be done right at the first sign-up screen.

• Choose your sensor: with several chest straps switched on nearby (in a class, for example), the app lists them all and you pick yours — it never connects on its own. • The code printed on the strap is shown in the list, and you can give each strap a nickname. • During a session the app reconnects only to the strap you chose.

• Fix: the full backup now carries your My tasks to the other device. • "Delete all" also removes the task library. • Backup messages show how many tasks were exported and imported.

• My tasks: create your own practices in the library — including with a guided breathing rhythm — and use them in measurements and in the plan. • New practices: Conscious hyperventilation breathing, with guided breath-holds and a reading of the response in each round; Cyclic Sighing; and the Resting Breath Pause mode, with its own screen and report. • PDF reports in A4 format, with an identification header. The patient report now uses plain language; the technical details are in the technical report. • Orthostatic Test — 30:15 Ratio: its own document, and blood pressure now shows both a drop and a rise on standing. • Task library right on the home screen. • Capture: a short signal window is no longer counted as complete.

Fixes PDF report generation on iPhone and iPad.

iPad support: Vagal Sense now runs full screen on iPad.

What's new • Single Measurement: record one moment on its own — rest seated or lying down, a task from the library, a free task you name yourself, or the recovery. It comes with its own report, which presents the measurement and its context without interpretations that an isolated reading cannot support. • Frequency domain: total power, LF, HF and the dominant breathing oscillation, with a check on how closely the guided pace was followed. • Poincaré and geometric indices (SD1, SD2, SD2/SD1, Stress Index) from 5 minutes of recording. Fixes • 2 cm margins on every page of the PDFs, so documents print without clipping. • Fixed the alignment of the Poincaré and histogram charts in the technical report. • Higher text contrast, and index bars now print in their proper colours. • Breathing guide keeps a steady beat through long sessions. • The capture timer now ends at the exact time.
