at the risk of sounding like an Orthograph shill, I've found the app has gotten easier to use and the tech support has never been an issue. In fact when I first bought the app they skipped me and walked me through it. That offer stands, as I've discovered wen updating.
I had to find my purchase receipt from the App Store to update to the current version. They now have a subscription model (no my favourite notion, but there appears to be an option to use it on an as needed basis), but my update included use of the tool for the next year.
