How Sync Works
StepSprite is built around a simple idea:
count first, sync later.
What happens on the device
Section titled “What happens on the device”StepSprite keeps track of:
- a running step total
- minute-by-minute step history
That happens on the device itself, not on a cloud server.
What happens on iPhone
Section titled “What happens on iPhone”When you open the StepSprite app near the device, the app:
- reconnects over Bluetooth
- reads live device status
- backfills recent minute-by-minute history
- updates StepSprite data in Apple Health if you enabled it
That is why your iPhone can stay on the desk while you walk.
How much history is stored
Section titled “How much history is stored”The customer-facing expectation is up to a month of step history stored on the device.
That means StepSprite can usually catch up even if you do not sync every day.
Foreground-first, on purpose
Section titled “Foreground-first, on purpose”StepSprite does not promise constant background Bluetooth sync on iPhone.
The intended behavior is:
- wear StepSprite all day
- open the app when you want to sync
- let the app catch up while the device is nearby
That design keeps the behavior more predictable and easier to support.
Add a screenshot of the app while it is connected and actively syncing recent history.
What goes to Apple Health
Section titled “What goes to Apple Health”If you allow Health access:
- steps are the default write category
- distance, calories, and workouts are optional
If you start and end a workout manually, StepSprite can also save an indoor walking workout.
