How to Save Your Ideas on Your Phone

I don't have a good solution right now. Right now I just open up obsidian and put it in on my phone or something like that, or I set myself a reminder for like an out we know at time. Maybe maybe the solution is to bookmark in raindrop a text file in Dropbox. You cannot paint your ideas to that text file in drop by. It used to be that we had more web based text editors because of the range of the not raindrop the Dropbox based text editors. That things that doesn't really exist much anymore.
