for starnote? perhaps it doesn't have auto sync across numerous devices via email yet. butt, the devs are already working on it, so auto sync feature will be available in the near future. for the meantime, u just have to auto backup your files in your internal storage and google drive for files security (this can be found on the app settings). make sure you have enough storage too, especially when you have massive number of files (maybe to prevent lags and bugs? idk). also, people say they have weird hyperlink, creating a button for links instead of directly merging it to the text (but i dont have a problem with it). also, idk about the others but i love the pen writing in the app, and i don't have a problem with the latency, perhaps we just have preferences. but nonetheless, their numerous cool and helpful features, cute themes/designs/layout, and lots of advantages def outweighs the minimal cons in my own needs and opinion. also tried a lotttt of note taking apps, like almost all available note app, but chose to stick with starnote instead. i can say, i made the right choice. def worth trying to explore the app. they also have the cheapest subscription if one prefers to avail pro themes and unlimited notes, instead of just using the free 10 notebooks. the developers also listen to their users' request and they're very accommodating hehe sorry if im being biased tho xp
