Simple fast log entry - a tool to enter QSO from your SOTA/GMA/WWFF activations and create the ADIF file - everything just in your browser. It allows you to enter QSO very quickly using a simple syntax. Data are stored only in your browser. The website does not collect any data about you.
I was heavily inspired by the FLE by Bernd, DF3CB - https://df3cb.com/fle/. His application works only on Windows and Linux using Wine, but I needed something working on macOS and/or Android tablet. I didn't need all the features, just wanted to log QSO from my WFF/SOTA/GMA activation.
