I’ve come to like this app a lot - it’s helped me run basic assays at home during the pandemic! **Developer response:** Thank you very much for the feedback. Hopefully the app is easier to use now with the one-tap help to the functions on a screen. Loading and saving the assay setups from/to a CSV file is supported, so that they can be edited outside the app and easily shared. If you have request for a new feature or improvement, please leave a comment. We are bringing the app to work on Mac and Windows, will keep you updated. ## Frequently asked questions about Spotxel® Reader ### What is Spotxel Reader used for?
