SonarPen: an inexpensive pressure-sensitive stylus that will work even with older iPads

A recent study has shown that children who use touchscreen gadgets from an early age will have difficulty keeping their pens in the correct position in the future. Despite the presence on the market of several electronic stylus for tablets and smartphones, in most cases they are either too expensive or only work with top-end tablet models. One Hong Kong-based company hopes to make a difference with the launch of the SonarPen, a cheap pressure-sensitive drawing stylus that works on all generations of iPad, even without 3d Touch support. Connection is via a 3.5 mm audio jack.

The SonarPen is a smart pen that bridges the gap between cheap rubber pens and expensive Apple Pencils. The gadget does not require batteries or rechargeable batteries to operate. To start using it, just connect it to an iPhone or iPad via the headphone connector, and in the case of the latest iPhones, where this connector is absent, a Lightning adapter is used. Pressure recognition is realized by encoding information into an audio signal, which is instantly converted by a mobile device into an image on the screen.

The number of possible uses of the SonarPen stylus directly depends on the application developers. At the moment, SonarPen manufacturers have prepared software for iOS gadgets. Android devices did not stand aside, but at this stage the gadget will work like a "blunt stylus" without recognizing the force of pressure. Full Android support is reported to arrive in June when the device goes free sale.

Two iOS apps are currently supported. These are ZenBrush 2 and ZoomNotes. But the creators of SonarPen assure that several more developers are already working on integrating the smart stylus into their products. Considering the popularity of the crowdfunding campaign (the required amount was not only raised ahead of schedule, but also doubled), it is likely that new applications with SonarPen support will indeed appear in the near future.

The low cost of the SonarPen smart pen remains its strong point over other similar products. At the start, it will be only $ 25. In the future, the retail price will increase to $ 30. This is a significant advantage over the expensive Apple Pencils, which sell for $ 100 and only work with the iPad Pro. While SonarPen will be able to interact with all gadgets, including older models of tablets and phones. Upon entering the retail market, the final functionality of the gadget may differ from the original idea, but if you have an old iPad and want to turn it into a drawing album for yourself or a growing child, SonarPen will be a good option.

Of course, if the screen of the device is malfunctioning or broken, even SonarPen will not help. In such cases, it is recommended to replace the glass of the iPhone or any other Apple gadget with our partners
