Why do measurements seem inaccurate or inconsistent after a Styku software update?

Software updates from Styku do not change how measurements or body calculations are made. If you noticed unexpected results after a recent update, the cause is something other than the update itself — and our support team can investigate specific profiles to help find it.

What Styku updates do and don't change

Calculations and measurements are not modified in software updates. A waist measurement, body fat estimate, or any other biometric is computed the same way before and after an update.
Updates may include bug fixes, performance improvements, and new features — but these do not alter how your members' bodies are measured.
If results look different between two scans, the most likely causes are scan quality, member positioning, lighting conditions, or computer performance — not the update itself.

Note for refurbished unit owners: Per Styku's refurbished unit sales terms, Styku does not guarantee identical measurement results, scan output, or performance compared to new units or other hardware generations. If you are using a refurbished scanner and notice persistent measurement variability, this may reflect expected performance variability rather than a software issue.

Common reasons measurements may vary between scans

Member pose changed. Even small differences in how someone stands — feet position, arm angle, posture — can affect measurements. Make sure members follow the same posture instructions every time.
Ambient light interference. Sunlight or bright overhead lighting can affect the depth sensor. Scan in a room without direct daylight coming in.
Poor scan capture. If the member moved during the 30-second scan, or the turntable rotation was uneven, the resulting 3D model may be incomplete or distorted.
Software is freezing or running slowly. A slow or freezing computer can interrupt the scan or processing steps, which may affect results. See the section below.
Member preparation. Unlike BIA devices such as InBody, Styku's 3D depth sensing is not reliant on hydration levels, so factors like eating, drinking, showering, or working out before a scan will not affect results. However, members should wear form-fitting clothing or undergarments for every scan to ensure consistent measurements.

If your software is freezing or running slowly

Slowness and freezing after an update are usually a sign that the computer needs maintenance — not that the software itself is broken.

Try these steps in order:

Shut down the laptop fully at the end of each day. Do not just close the lid or let it sleep. A fresh restart clears memory and keeps the system running well.
Check for Windows updates. Open Settings → Windows Update → Check for updates. Install any available updates and restart the computer.
Close other programs while scanning. If other apps are open in the background, they compete for memory and processing power.
Check available storage. Open File Explorer and check how much free space is on the C: drive. If it is below 20 GB, the computer may slow down significantly.

If the computer continues to freeze after these steps, the hardware may no longer meet the minimum requirements to run Styku Studio smoothly. Contact support to discuss options, including transferring your license to a newer computer that meets current requirements.

Note: If you need to view scan profiles on an additional Windows computer, it is possible to install Styku Studio on that machine and log in with your existing Styku account using a viewing license key. If you do not have a viewing license key, you can request one through the Business Portal at https://styku.com/portal.

How to report a suspected measurement issue

If you have specific scan results that look wrong, our team can look into individual member profiles. When you contact support, include:

The member's name and email address as it appears in Styku Studio
The approximate scan dates you are comparing
A description of which measurements look off and how they differ
Whether the issue affects one member or multiple members

This gives our team what they need to investigate quickly.

If this resolves your issue, no further action is needed.

If the problem persists, contact support and include: the affected member profile name and email, the scan dates being compared, which specific measurements appear incorrect, a description of any freezing or slowness (when it happens and what action triggers it), and the current Styku Studio version shown in the app.

Applies to: Styku Studio V5, all Styku scanner configurations
