Thanks, guys, there are some really helpful bug reports in this thread. In particular, thanks for including the sample images, @Tim, and the details about what device(s) and film(s) you’re all using. Having that information is very useful to me.
The biggest problem in the current beta is definitely inaccurate/inconsistent frame detection, so that’s going to be my focus for the next few releases.
Thanks again to all of you for backing the project on Kickstarter - as you can see, there really is a lot of work to do to make this into a finished app, and it’s your support that’s making it possible for me to spend the necessary time to get everything working!
