Good initiative, but might be better idea to provide less apps with similar functionality and concentrate on one that actually works. I'm still searching for a decent privacy respecting (no internet, no sync, no google account required) app for simple reminders and notes, but neither of Secuso apps worked, mainly reminders in "To-Do-List" were not working at all. If anyone has made a simple reminder/note app, similar…
I think by having apps for so many use cases they may have better luck picking up enough users. I for one will be checking out the rest of their work based on that experience with the barcode scanner.
There's also something to be said for many small programs that do one thing well. See also the "Simple" suite of apps, which seem to have a similar philosophy.
