Nice implementation of Processing

Frogg GmbH´s implementation of a Processing IDE for iOS is straightforward and easy to use both for the beginner and for the experienced Processing developer. It s nice to be able to test out simple to moderately complex sketches on the go. I do have a few suggestions: 1) a simple help system for beginners focusing on iOS-specific interactions with the hardware would be nice (camera, accelerometer, gyroscope, GPS? but, perhaps, some of these have not been or will not be implemented), 2) integration with other software tools (for instance, GitHub clients such as Working Copy), 3) a means to create and interact with a “data” directory and to import and export resources, and 4) a means to interact over Serial with external devices (ultimately, Arduinos, etc) would be nice. Thanks for taking the time to create a fine app.

This could be awesome

The basic implementation for Processing is done well. Seems like a few functions are missing, but a great start. To make this a 5 star app and worldwide adoption, consider the following suggestions. If time is the issue, I bet many users would be willing to pay $1 or more to complete this.

1) implement Processing version 3 functions so sketches are fully portable
2) add multi-file support
3) add library capability with some type of library manager to import or delete libs
4) add capability to import and export sketches to a host computer. Maybe use Dropbox or or other existing file sharing tool
I look forward to future enhancements.

No dev support

The app is a buggy, and don’t expect support. I’ve emailed the devs, and never got a reply. Project naming is broken, so you can’t name files with underscores or numbers, which is common for processing sketches. More complex effects such as blendMode(); don’t work. Simple sketches are possible, but if you want to make something more complex you’ll have to resort to video editing apps, or using a real IDE on a desktop.

Hey this app is free and open source. Please fix it yourself before giving me 2 stars 😥
