We have recently updated our app, "Time Lapse Calculator". There is now an advanced calculator option from within the app which will give you greater control over your time lapse. Here are some screenshots:
We hope you find the update useful, we are working on improving it more and more. So just send us some feedback from within the app or send us an email at feedbackdmb@gmail.com. We look forward to hearing from you and hope you enjoy the app.
If you do not have the app already, you can try a free version here:
