My wife and I have tried several note-taking apps ovrer the years -- Evernote, OneNote, etc. -- and theyre fine for what they do. But wed always have problems keeping the "grocery list" in sync. One of us would be editing it only to find the other still had the note open, and you ended up with a syncing conflict to resolve. It was a royal pain.
Thats why we love Our Groceries so much. Rather than being a comprehensive note-taking app with tons of features and options, it went the route of being a solid, reliable, easy-to-use grocery list. Instead of being a jack of all trades, it mastered one -- and were very happy with the results. Since we switched over to Our Groceries about a year ago, we have not had one syncing problem. Not one! Outstanding!
