I’m currently working on my own online dive app that is responsive so it’s mobile friendly. I have a csv option built into the app so I can download it to excel and do pivot tables with the data if I want. Most of my diving has internet service and if it doesn’t I’ll hand write and add it later. I’m not going to add my other dives to it but I did add the ability to set a start dive number and hours for dives in other logs such as here on DB. Without logs being standardized and impossible to prove make sure you have your card and know the last five dives you did.
