“Finally I can use
the internet as before.”

The first browser to compensate for

Reconnecting Parkinson’s patients with the digital world.

Millions of Parkinson's patients worldwide suffer from tremors. This makes reading and navigating on smart devices such as tablets extremely difficult. The browser app Staybl uses virtual counter-movements to compensate tremors in real time. Parkinson's patients and all other people suffering from tremors can finally surf the internet comfortably and smoothly again – and enjoy all the benefits of digital networking.

Key features.

Smart solutions for a better browsing experience

Staybl is designed from the ground up to meet the needs of Parkinson's patients, from the customizable tremor compensation, high-contrast design, a particularly legible font, and general ease of use.

Real-time compensation

Staybl uses the smart device's accelerometers to compensate for a tremor. To do this, the app performs a countermovement to the display in real time.


Users can choose from several presets designed for different tremor strengths. Depending on the selected preset, the browser window will shrink to provide additional free space to compensate for tremor movements.


Staybl was developed in close cooperation with Parkinson's patients. From the menu navigation to the positioning of individual buttons to their size and sensitivity, the usability is optimized for their needs.

Browser features

Bookmarks, history, tabs, you name it: Staybl has all important features that standard browsers offer, letting you surf smoothly despite the tremor – without missing the comforts you’re used to from well-known browsers.

Find the answers to some of the most frequently asked questions about Staybl.


Can I also use Staybl on my smartphone?

We plan to evolve Staybl for smartphones in the future but it is currently optimized for iPad. Staybl works best on advanced hardware with a refresh rate of 120hz and a screen large enough for a frame of a few centimeters around the browser window.


Is Staybl also available for Android?

Unfortunately, not yet. Since Staybl is a non-commercial project, we are taking it one step at a time. An Android version is planned, but a release date has not been set.


Staybl does not run smoothly on my iPad. Why?

A screen refresh rate of 120hz is needed for Staybl to run smoothly. iPads made before 2017 still have a lower refresh rate which can lead to jerky motion.


Does Staybl collect user data?

The Staybl app does not collect or forward any user data to the developers of the application or to third parties.
