If I were to do it all over again, I’d simplify things even further. I’d start by testing the idea with just the offline version. For syncing, I’d focus on syncing the data itself, just the database records and not the user actions. Instead of replaying every action, I’d track which records were modified and sync only those. No need to capture what changed, just that record got changed. Hopefully that makes sense.

The business is doing alright, but what really keeps me going is that the app is something I genuinely wanted for myself. I use it all the time, it's always open in the background, so that keeps me motivated.
