What it costs

Totals use prices stored on the app pages. A missing price is left blank instead of guessed.

How to choose

  1. Start from the job, not from the app you already pay for.
  2. Use the free option when its limit covers the work.
  3. Pay for the leader when that job is the one you do every day.
  4. Keep private files on a model you can run yourself.
  5. Read the date. A leader can move after the next check.
