How it works
Walk first. Sync later.
StepSprite keeps counting on the device all day, whether you are at your desk, walking outside, or leaving your iPhone on the desk. Open the iPhone app when you want to sync everything to Apple Health, or when you want to save a specific workout.
Wear it and forget it
Once it is paired, StepSprite keeps counting on the device all day without asking you to remember anything.
Up to 30 hours stored on the device
StepSprite keeps the running total and minute-by-minute history on the device, so one quick sync a day is usually enough.
Open the app when you want more
The app backfills StepSprite steps into Apple Health, adds estimated distance and active calories, and can save an indoor walking workout when you start one.
The iPhone app
The iPhone app keeps it easy
Most of the time you can ignore it. Open it when you want to sync, check the device, or save a workout.
Workouts
Start and end a workout cleanly, then save it as an indoor walking workout in Apple Health.
Stats
See Today’s Steps, This Week, Step History, Workout History, and optional daily and weekly goals.
Device
Check battery, firmware version, device state, connection mode, and charging mode from the phone.
Firmware updates
Install firmware updates from the iPhone app and keep the device current without breaking out a cable.
Tracks all day
StepSprite keeps counting on the device, even if your iPhone is still sitting on the desk.
Sync once a day
It stores up to 30 hours of step history, so a quick daily sync is enough for most people.
Easy recovery
If Bluetooth gets stuck, the app can rescan and recover without losing the data already stored on the device.
Why ankle works
Built for people who type while they walk
If you work from home with an under-desk walking pad, you already know the gap: your legs are moving, but your hands are parked on the keyboard. Wrist trackers look for arm motion, so they miss the step signal.
StepSprite sits at the ankle or shoe, where the step motion actually is. That makes it a better fit for slow, steady desk walking than a watch on your wrist.
Wear it with the ankle strap or weave it into your shoelaces. It stays secure, low-profile, and out of the way during a normal workday.
Privacy
No account. No cloud. Just your data.
The app keeps your StepSprite activity and Apple Health in sync. It also gives you workouts, device status, and firmware updates. There is nothing to sign up for and no server in the middle.
- No account required
- No cloud syncing
- No health data sent to StepSprite servers
- No monthly subscriptions
- No AI training on your data
- Your step data lives on your phone and in Apple Health only

FAQ
Does it arrive ready to use?
Yes. StepSprite arrives as a finished product. Charge it, pair it, and wear it.
Founders Edition just means this is the first small production batch.
How accurate is it at desk-walking speeds?
StepSprite’s firmware is tuned for slow, steady desk-walking pace (typically 1–3 km/h, 60–100 steps per minute). It filters out vibration and chair movement while staying sensitive to ankle motion.
It is built for the exact case where wrist trackers fall short: working at a keyboard on an under-desk walking pad. It won’t be perfect because step counting never is, but it is meant for this job instead of regular wrist walking.
How does it sync to Apple Health?
The StepSprite iPhone app reconnects over Bluetooth, reads the device’s minute-by-minute step history, and writes StepSprite steps into Apple Health. It also adds estimated distance and active calories for StepSprite activity, and it can save indoor walking workouts when you start and end one. StepSprite stores up to 30 hours on the device, so one sync a day is usually enough. No account needed, no server involved.
Does it only work on a walking pad?
No. StepSprite tracks your steps throughout the day, indoors and outdoors. If you wear it to work, out for a walk, or around the house, those steps count too.
Do I need to keep my iPhone with me all day?
No. Your iPhone can stay on the desk while StepSprite keeps tracking on the device. It stores up to 30 hours of step history, then backfills everything into Apple Health when you open the app later.
No account, no cloud — really?
Really. No signup screen, no email required to use the app, no health data leaves your phone. The app communicates only with your StepSprite device (Bluetooth) and with Apple Health (local, on-device API). Nothing is sent to StepSprite servers. No AI training on your data.
Shipping, returns, and support
Shipping: Continental EU only for Batch 1. Orders ship from Sofia, Bulgaria. Delivery takes 5–7 business days to most of Western Europe. Shipping is charged separately.
Returns: 14-day right of withdrawal as per EU consumer law. Unused returns are refunded in full. If the device comes back used or worn, diminished value may apply. Return shipping is at your cost.
Support: Email hello@stepsprite.com. Rob responds personally, typically within 24 hours.
Do I need to open the app for every walk?
No. StepSprite keeps tracking on the device all day. Open the app when you want to sync your steps or when you want to save a specific walking workout.
Will there be an Android version?
Yes. Android is on the waitlist and planned for Q3 2026. This batch is iPhone-first. If you’re Android-only, you can still reserve and join the waitlist.
Who is behind StepSprite?
StepSprite is built by Rob Ivanov at Worbee EOOD, a small company in Sofia, Bulgaria. Rob is a software engineer and Fractional CTO who built StepSprite to solve his own problem: walking 5 km on a treadmill desk while his Apple Watch said 0 steps. He designed the hardware, wrote the firmware, and built the iOS app. When you email support, you’re talking to him.
The story
Why I built this
I bought a walking pad so I could work from home without sitting all day. First session: 45 minutes, maybe 4,000 steps. My Apple Watch said: 0.
I tried the workarounds. Phone in my sock. Apple Watch on my ankle. Cycling mode. They all created a new problem.
So I built the version I actually wanted: an ankle tracker tuned for slow desk walking, plus an iPhone app that keeps Apple Health up to date, handles indoor walking workouts, and lets me update the device from the phone. No account. No cloud.
I wear it during normal workdays. It does the job and gets out of the way.
