I have just designed a simple Webviwer calendar (using FM19 add-on). I want to use it on my iPad, desktop and iPhone and making sure that the information keyed in are synced. Can anybody advise what is the best and most economical way to do this? Someone suggested AWS but its only 1 app and for my own use.Using AWS seems to be like an overkill. Hope to hear from someone soon. Thank you all in advance.

ideally you don't sync. you simply access this hosted file from any platform. for that, you need to host the file.

I see. Thanks so much for replying. I suppose I will have to host it. no choice.
