Catches
  • Free and Go may show ads. Plus ($20/mo) is the cheapest ad-free plan
  • No annual billing on Go, Plus or Pro, so no discount for committing
  • Most limits say 'limited' or 'expanded' rather than giving a number, so it's hard to know when you'll hit the wall
  • Pro limits are 'weekly limits (average use)', with no number published
  • Its own help page warns advanced-model access may be limited during weeks of heavy use
  • Max is $200/mo, a big jump from Pro
