The SonarPen 2, a successor to the original SonarPen, has launched on Kickstarter, offering a more affordable alternative to the Apple Pencil with advanced features like tilt detection and an improved tip. This upgraded stylus still relies on sound waves instead of Bluetooth, eliminating the need for battery charging.

First introduced in 2018, the SonarPen debuted as a cheaper alternative to the Apple Pencil by using audio signals transmitted to the iPad over a cable instead of Bluetooth. The creators of the SonarPen have now upgraded their product with a USB-C version, introducing additional functionality, including tilt detection and an improved tip that closely resembles the Apple Pencil's.

The SonarPen 2 is currently available for preorder through the Kickstarter crowdfunding campaign, with shipping estimated to start as early as April 2025. Early bird preorders can snag the SonarPen 2 for around $32, with full retail pricing expected to be closer to $45. This pricing makes it a more affordable option compared to other third-party iPad styluses that support features like tilt detection and pressure sensitivity, such as the $70 Adonit Note Plus.

In addition to tilt detection, the SonarPen 2 includes integrated cable management, supports features like palm rejection, pressure sensitivity, and a customizable shortcut button. The improved tip can be replaced as it wears down, similar to the Apple Pencil's. However, the SonarPen 2 only works when connected to a USB-C or Lightning port, specifically designed for iPad models with a smart pen screen digitizer.

One limitation of the SonarPen 2 is that apps need to support its features like tilt detection and shortcut buttons specifically. Currently, the list of fully supported apps is not extensive, including ibis Paint X and Zen Brush 3. For apps that haven't explicitly added SonarPen 2 support, the stylus will function like the original Apple Pencil but without pressure sensitivity.

The SonarPen 2's innovative approach to stylus technology, relying on sound waves instead of Bluetooth, has the potential to disrupt the market for Apple Pencil alternatives. As the product gains traction and more apps add support for its features, it could become a popular choice for artists, designers, and iPad users seeking a more affordable and feature-rich stylus option.

With its Kickstarter campaign underway, the SonarPen 2 is poised to make a significant impact in the world of iPad accessories. As the market for Apple Pencil alternatives continues to grow, the SonarPen 2's unique approach and advanced features make it an attractive option for those seeking a more affordable and innovative stylus solution.
