The life-admin hit list

Every bill worth
a second look.

The dashboard covers the whole boring lot. We're switching on the cleanest checks first, and the rest are queued up as the benchmark data grows.

Quick bill check

Give a bill a quick MugCheck

MugCheck uses the current benchmark available for the bill you select. Some checks use reviewed current evidence and others use broader early ranges. Nothing is saved unless you choose to contribute where that option is available.

The score people screenshot

Meet the Tightarse Index.

One honest score out of 100. Low bill, high score. It's cheeky enough for the group chat, but it's built on real benchmark ranges and confidence — never vibes.

Share bait, but honest

Turn a boring bill into a badge of honour.

Below the benchmark and you're an elite household negotiator. Cooked, and, well… someone's funding a quarterly bonus.
