How we choose

Every app is checked before it gets in.

We check what it does, how it handles your data, and whether it works. Then we keep checking, so you never have to.

How we choose our apps

  • Vetted before entry

    Function, reliability, and data handling.

  • Watched after entry

    Performance and feedback, followed over time.

  • Reviewed every 90 days

    A place in the den has to be earned again.

Use the app. Or just ask.

Use Receipt Weasel right in your own ChatGPT or Claude chats. Muse connects when you ask it to, and Grok through a custom connector.
