There is (was?) an issue with weathermeister that was brought to their attention some time ago that they never fixed to my knowledge. If you get a weather briefing, it will only give you NOTAMS along your route of flight UNLESS you are within a close physical distance to the actual center location. May not seem like a big deal, but if you want to get the big picture in case of a deviation, you will not. They were very unresponsive to suggestions and to fix another bug that deleted a lat/long if you edited your route. I use Foreflight myself.
