I use nvAlt for Simplenote on Mac where I chose to keep the file in text format in a Dropbox folder and it also sync to Simplenote server which easily makes the data available to mobile app. So Simplenote server does the sync between apps and since I keep the data in Dropbox folder the data is synced/backed up (I separately backup that folder as well) there as well. (To be honest that works better for me than FSNotes' complicated way of doing this. I wish they had a way to do that in Mac app while still utilising invisible iCloud Sync; but without me having to specify a dozen places for storage, sync, external folder etc etc) Joplin is FOSS.
