Tired of consuming? Let's enjoy creating! Based on Scratch, Pyonkee provides a real, programming environment, anytime, anywhere! Pyonkee is a new dynamic media for developing various ideas. By combining visual blocks, kids/adults are able to create original games, animations, and stories on their own. Through the programming process, we will learn about logics, productivity, creativity, and collaborations. Pyonkee has been developed from the open-source code of "Scratch 1.4" from MIT Media Lab. Since Pyonkee is fully compatible with Scratch 1.4, millions of existing Scratch projects can be used for reference. Pyonkee's user interface is optimized for touch devices. We do not need cumbersome typing, even a mouse. Just write programs wherever you like. Pyonkee nicely supports pinch-in/out, and font scaling for small devices. Moreover, sound recorder and camera are provided for importing your sounds and pictures into the projects. We can mix various media on Pyonkee and program them. Moreover, you can share your projects via AirDrop, e-mail, iCloud, and other cloud storage services. From the version 2.1, you are able to create programs using various iPad sensors and Mesh network protocol. From the version 2.3, more than 100 instruments are available in sound block. You can even play other synth app's sounds by enabling Virtual MIDI. From the version 2.20, Pyonkee is able to connect to micro:bit. You can get values from various sensors and send analog/digital signals to the pins. By combining the micro:bit with Pyonkee, you can enjoy an even wider world of programming. Dive into the fun of visual programming!
Verdict
The clearest difference is rating: DIY Nano HD at 5.0 against Pyonkee's 3.7. DIY Nano HD also leads on review sentiment (80% vs 62%) and iOS requirement (6.0 vs 13). Pyonkee's advantage is ratings volume (53 vs 2) and update cadence (every 4 months vs every 10 months). On price, ads, in-app purchases and monetization model there is nothing between them.
