Accountability Apps: The Four Mechanisms That Actually Work

How we write these

Three rules, because this category is full of invented statistics.

  1. Every number has a source you can open. If a claim cannot be verified it gets dropped, not hedged into vagueness. The accountability statistic everyone quotes cites a study that does not exist, and we say so.
  2. Competitors get their strengths stated. Every comparison names what the other tool does better and links its own documentation, so you can check whether we described it fairly.
  3. We say what Commit isn't. iPhone only, public beta through TestFlight, not on the App Store, and the published charitable-giving figures currently read $0. Pretending otherwise would make everything else here worthless.

Word counts on the cards above are body copy — everything in the article minus the breadcrumb, the updated line, the disclosure strip, the contents chips and the link list at the end — rounded down to the nearest 50. The exact figure is in each page's structured data.
