Signal app
I've tried notebooks, spreadsheets, pictures but I always think / remember something when I'm not near the vehicle / computer. I now use the Signal app on my phone by starting a new "chat group" for each piece of equipment. I can add a pic and details in the title (VIN / SN) and then I can add notes / pictures whenever I have the time. It's definitely not perfect but it's the only system I've used that works for more than a year (I've never been consistent enough with anything else). I can search each group separately for key words if I'm looking for history details (oil, leak, windshield, exhaust, etc).
Thinking about it now it would be nice to have a "folder" that I could store all the maintenance groups in.
Cool things I like about this approach:
- I can add people to the group who are interested / involved / need to be in the loop, can access / update from multiple phones, PCs
- free, secure backup to the cloud of all txt but limited media (can pay for 100GB I think)
- desktop app
- ability to add files (PDF, txt, etc), sound & video
