Thanks for the tips! They’re super helpful! I’ll add a check for .flogo files.
As for the void connectors, I added them to reproduce the flowchart exactly as it was drawn. The app is designed for 14-year-old students, so I preferred to go this route.
There’s no automatic saving, but I think it depends on the device, because if Flogo stays in the background, the project doesn’t get deleted.
Thank you! I look forward to your feedback

I built Flogo: a powerful flowchart-based visual programming app (free, no ads)
Hi everyone, I recently launched Flogo, a visual programming app that lets you build and simulate flowcharts with real logic execution. It’s designed for both students and developers, and supports things like:
Conditional blocks (if, for, while, dowhile)
Real-time simulation (console or navigation mode)
Dynamic input
Plotting graphs (plot() function)
Complex numbers, matrices, and over 100 built-in functions
Free, no ads, available for iOS & Android
If you're into visual coding, algorithm design, or teaching programming, give it a try! Feedback is welcome.
