FAQ
⚙️ GENERAL
What makes Prolo Ring different from other smart rings?
Most smart rings are designed mainly for passive sensing or a few simple gestures. Prolo Ring is built for active, full-featured control.
Its wider touch surface gives your thumb access to a trackpad and multiple control zones, enabling full cursor movement, clicking, dragging, scrolling, zooming, navigation, media controls, shortcuts, and more—all directly from your finger.
Instead of requiring you to learn unfamiliar gestures, Prolo Ring uses familiar tactile actions such as tapping, swiping, and pressing and holding. This layered yet intuitive control interface lets one ring handle a wide range of interactions across computers, phones, tablets, AI glasses, and XR devices.
What devices does Prolo Ring work with?
Prolo Ring uses standard Bluetooth HID and works across:
- Computers: Windows, macOS, Linux, and ChromeOS
- Phones and tablets: Android, iPhone, and iPad
- Wearables and XR: AI glasses, display glasses, and compatible VR/XR headsets
- Other compatible devices: selected smart TVs and streaming devices
No driver installation is required—pair it over Bluetooth and start using it. Prolo Studio is optional for customizing gestures, shortcuts, macros, and profiles.
Can one Prolo Ring switch control between all my devices?
Yes. Pair Prolo Ring with up to three compatible devices and use a simple Tap + Hold to switch between them. Move from your computer to your phone, tablet, AI glasses, or XR headset using the same ring.
How long does it take to learn Prolo Ring?
Prolo Ring uses familiar gestures such as swiping, tapping, and pressing and holding. These gestures are grouped into different modes, allowing the same intuitive motions to perform related actions across cursor control, navigation, media, and shortcuts.
Most users learn the core controls in about five minutes. For the best experience, use a light touch and glide naturally rather than pressing firmly.
Does Prolo Ring require an app or driver?
No. Prolo Ring connects directly to compatible devices through Bluetooth and works without installing a driver or keeping an app open.
Prolo Studio is optional and used to customize gestures, shortcuts, macros, profiles, sensitivity, and other advanced settings. Once configured, those settings are stored on the ring and continue working independently.
Do the touch controls require firm pressure?
No. Prolo Ring’s touch surface is highly sensitive, so only a light touch is needed. Gently glide your thumb across the trackpad rather than pressing down firmly.
For taps and swipes, use light, quick movements. Relaxed thumb movements generally provide smoother, more accurate control and help reduce unnecessary effort during extended use.
💍 DESIGN, FIT & COMFORT
Is test wear required to choose my size?
Yes. Because Prolo Ring uses a unique wide-band design, its fit cannot be determined reliably from standard narrow-band ring measurements.
Finger size also changes naturally throughout the day, so we recommend wearing the sizing sample for at least one full day before selecting your final size.
Ring-size adjustment shims are included for fine-tuning if you prefer a slightly tighter fit. As a general rule, choose a size that feels secure but never tight at any point during the day.
How do I test wear and find the correct size?
For the most accurate fit, use our ring sizing kit. You can also download this 3D printable file.
Wear the test ring for enough time to evaluate comfort, especially when your fingers naturally expand during the day.
Choose a size that:
- stays secure during thumb gestures
- slides over the knuckle without excessive force
- does not create pressure, numbness, or discomfort
- remains comfortable during extended use of moving, tapping and pressing.
Then submit your confirmed size through the personalization link.
Can I use my usual ring size?
Not reliably. Standard jewelry sizes are often measured using narrow bands, while Prolo Ring has a much wider profile. Wide bands generally require more room and may fit differently even when the printed size number is the same.
Always confirm your size through test wear rather than ordering from your usual ring size alone.
How should Prolo Ring fit?
Prolo Ring should feel secure but remain slightly loose and comfortable throughout the day. It does not use biometric sensors that require constant skin contact, so there is no benefit to wearing it tightly.
The ring has a rigid internal structure with space allocated around its rechargeable battery. Choose a size that never creates pressure as your finger naturally changes size during the day. Included sizing shims can be used for small adjustments if needed.
What sizes are available?
Prolo Ring is available in US sizes 7–18. Included adjustment shims can reduce the fit by approximately ½ to 1 size.
Why does Prolo Ring use a wide-band design?
The wide band provides enough usable surface for a thumb-operated trackpad, tactile controls, and multiple gesture layers.
This enables cursor movement, clicking, dragging, scrolling, zooming, shortcuts, and media control in one wearable device—rather than limiting the ring to a few fixed buttons or simple actions.
Which hand and finger should I wear it on?
Prolo Ring is designed to be worn on the index finger and operated by the thumb of the same hand. You can wear it on either your left or right hand, depending on your preference and workflow.
Can I use Prolo Ring if I have small hands?
Yes. Prolo Ring is available in multiple sizes, and the included ½-size adjustment shims can fine-tune a slightly loose fit.
For example, a size 7 Prolo Ring can be adjusted to fit closer to a size 6 and may suit someone who normally wears a smaller narrow-band ring. Because wide-band sizing differs from standard jewelry sizing, test wear is still required.
Is Prolo Ring comfortable for extended use? Will my thumb get tired?
Prolo Ring weighs approximately 4–5 grams and is designed for light, intermittent thumb gestures throughout the day. The touch surface is highly sensitive, so taps and swipes should be quick and relaxed rather than forceful.
Most actions require only short thumb movements, with natural pauses while typing, reading, or viewing content. Users can also disable unused gestures, simplify the control layout, or adjust sensitivity to reduce unnecessary movement.
With the correct size, the ring should feel secure without becoming tight or creating pressure. Test-wear the sizing sample for at least one full day, and take a break if you experience fatigue or discomfort.
🖐️ USAGE & FUNCTIONALITY
How do I pair Prolo Ring with a device?
Pairing works like connecting a Bluetooth headset.
- If the ring has no saved Bluetooth connections, it automatically enters advertising mode and appears in the device’s Bluetooth list.
- If the ring already has saved connections, it first tries to reconnect to one of them. To pair a new device, manually enter advertising mode with 2× Tap, then Press and Hold the Modstrip.
Then:
- Open Bluetooth settings on your device.
- Select Prolo Ring from the available devices.
- Confirm pairing.
Once connected, Prolo works as a standard Bluetooth HID input device.
How many devices can it remember, and how do I switch between them?
Prolo Ring can remember up to three paired devices, but it connects to only one at a time. This prevents accidental input from being sent to multiple devices.
To switch to another paired device, perform 1× Tap, then Press and Hold the Modstrip. The ring will disconnect from the current device and reconnect to the next saved device.
Can I use Prolo alongside my regular mouse and keyboard?
Yes. Prolo works alongside your existing mouse and keyboard without interference. It acts as an additional input device, letting you use cursor control, gestures, shortcuts, and macros without replacing your current setup.
What if my PC does not have bluetooth?
Use a standard USB Bluetooth adapter. Once the adapter is installed and recognized by your operating system, pair Prolo Ring through the computer’s Bluetooth settings as usual.
Compatible options include:
Make sure the adapter supports Bluetooth Low Energy and standard HID input devices.
What is Prolo Studio, and is it free?
Prolo Studio is the free companion app for configuring and customizing Prolo Ring. It lets you:
- Map gestures to actions
- Create shortcuts and macros
- Adjust cursor and control settings
- Configure advanced features
- Create profiles for workflows such as work, presentations, media, or gaming
Prolo Studio is free to download for Windows, macOS, and Linux. Once configured, your settings are stored on the ring, so the app does not need to remain open during everyday use.
Are custom gestures and profiles stored on the ring, and do they work across devices?
Yes. Custom gesture mappings and profiles can be saved directly to Prolo Ring, so they remain available when you switch between paired devices without reconfiguring the ring.
Actions based on standard Bluetooth mouse, keyboard, and media commands work across compatible devices. Some platform-specific actions—such as launching applications or running computer-based macros—may require Prolo Studio to act as a translator on that computer.
You can create profiles for work, presentations, media, gaming, and other workflows, then export or import them between computers for easier setup.
Can I disable unused gestures or create a simpler control layout?
Yes. Each mode, individual gesture, and optional feature can be enabled or disabled.
You can keep the full range of controls or create a simpler layout with only the actions you use most. Disabling unnecessary gestures can make the ring easier to learn and reduce accidental triggers.
Will the cursor move accidentally while I type?
Prolo is designed to prevent accidental cursor movement during normal typing. The trackpad is positioned away from typical keyboard contact, while built-in detection filters ignore unintended touches and respond primarily to deliberate gestures.
Unused gestures and modes can also be disabled for a simpler, more reliable setup. When the ring is not needed, you can lock it completely and unlock it again with a tap-and-hold on the Modstrip.
Can I use two rings at once?
Yes. Two rings can connect independently to the same host device, similar to using multiple input devices.
For example, one ring can handle cursor control while the other provides shortcuts, or both can be configured for dual-hand shortcut workflows. The rings do not communicate or synchronize directly with each other.
What can I use Prolo Ring for?
Prolo Ring can be used across productivity, presentations, media control, creative software, CAD, gaming shortcuts, accessibility, AI workflows, display glasses, and XR applications.
It can work as a primary controller or alongside your existing mouse and keyboard, with gestures mapped to cursor actions, shortcuts, macros, media commands, and other frequently used controls.
