great questions and great to hear you are logging your cases! its an incredibly important part of self auditing and self improvement.. I have seen many databases fail over my time.. I have always been old school with a big diary and then I used to transfer them on to an excel spreadsheet.... here's a sample logbook at this address anaesthesiacollective.com/education/introductory-training/the-basics/ otherwise I've heard Vaper is good, but I have no personal experience of it.. let me know if you find a good one! also you should ask on the ABCs Facebook group
