There was an IOS app a friend recommended that is only configured for Kiss Sidewinder right now. Since I dive the Spirit, essentially same unit. I did not like that app since I’m used to doing things already with my checklist. I don’t need an app when I have my own checklist I can check off, screenshot, and erase what I’ve done to it for the next time. Also costs nothing since the Notes app comes as part of iOS.
Since you’re on Android, I would look at the stock apps you already have if there’s something comparable to iOS Notes app. Otherwise, I’m sure there’s tons in the Google Plat store that would work.
