One great aspect is that joplin supports iOS 8+. My Ex needed to write a big dissertation that she just couldn't make progress on (unsurprisingly). Her work laptop is too bulky to carry around every day unfortunately. So at some point I figured she could use my old ipad mini 1 with a size-fitted logitech "ultrathin keyboard" (that magnetically holds onto the ipad, making it one piece for storage) that I impulse bought and never used. So hardware was there, but looking for a markdown editor that supported sync and that old device + her windows laptop was not fruitful. Except well, short story: joplin is awesome for that. She could use the ipad to write a few minutes here and there during transit and was able to complete it. The markdown file is then converted to latex/pdf using pandoc + pandoc-citeproc (for citations using a bibtex-file). Support for antiquated iOS versions is rare (making the ipad mini 1 useless in many cases although it still appears to be a capable device) even though many apps don't seem to have a need for higher versions. I suspect that most apps use frameworks that have a version cutoff to reduce complexity if that even makes sense.
