Custom haptic Flows

1. Segment
   One haptic + an interval
2. →
3. Loop
   1–3 Segments
4. →
5. Flow
   1–30 Loops

Segment is the smallest rhythm unit, measured from the start of one haptic to the start of the next. Loop plays 1–3 Segments in order and repeats them a specified number of times. Flow arranges multiple Loops into a complete activity.

1. Create and name a Flow.

   Save up to 15 Flows. A name can contain up to 24 weighted characters, roughly 12 Chinese characters.

2. Add a Loop.

   Choose one, two, or three Segments and 1–99 repetitions. Loop names can contain up to 12 weighted characters, roughly 6 Chinese characters.

3. Edit each Segment.

   Choose a haptic pattern and an interval of 1–180 seconds until the next Segment starts.

4. Arrange and save.

   Flows and Loops can be duplicated or reordered. Saving writes to iPhone first; normally, return home and tap “Sync” to publish to Watch. Changes affecting Flow reminders automatically publish the full configuration. Sessions already in progress remain unchanged.

When increasing a Loop from one Segment to two or three, each new Segment defaults to “Single short + 1 second.” Reducing the count removes trailing Segments immediately, without an additional confirmation.

A Segment interval is not a wait after the haptic ends. It begins when the current haptic starts and ends when the next one starts. The final interval of the final Segment must also finish before the Loop is complete.

The ready screen shows the Flow name, Loop count, and active duration. Tapping “Start” fixes the settings for that session. Later syncing, renaming, reordering, or deletion on iPhone will not change the activity in progress.

The first haptic is the pattern you chose for Segment A; no extra start cue is added. The Cycle Ring’s nodes and arc lengths represent Segments and intervals. Its center shows the current Loop name and repetition count.

Pausing preserves the current Flow, Loop, repetition, Segment, and exact remaining interval. Resuming does not replay a haptic that already occurred. Exiting early returns to the ready screen without a completion cue.

After a non-final Loop’s last interval, bluebell plays a completion cue and waits for confirmation. It does not automatically enter the next Loop. The continue button is temporarily disabled during that cue to prevent overlap with the next Loop’s first haptic.

When the button becomes available, tap “Start next Loop.” On a Double Tap-capable model running watchOS 11 or later, you can also tap your thumb and index finger together twice. Both actions do the same thing.
