About Flowlane

Research on choices.
Evidence for action.

Flowlane identifies potential issues in UK and Australian customer flows and links each finding to supporting evidence.

Your team receives specific recommendations, with a focused recheck after implementation.

The approach

Identify and document. Recommend and recheck.

Pricing, subscription commitments and cancellation are experienced as a flow. Flowlane follows it step by step.

01

Find it

Spot the step that needs a look.

02

Prove it

Keep the screen, the step and the rule it touches.

03

Fix it

Get a specific change to assess. Your advisers decide.

04

Keep it fixed

Compare the revised flow with the finding, after every release.

From research to practical reviews.

Flowlane comes out of doctoral research on manipulative design, published at leading conferences in security and human-computer interaction. The venues below hold CORE's top two ranks, A* and A. The work studies how interface design shapes decisions in real user flows.

How we work

Three principles in every review.

Evidence stays separate

Website sources, annotations and assessments stay distinct in the record.

Your team implements

Your team or agency makes the specified change. Your advisers assess the rule.

We recheck

Flowlane reviews the changed flow and records any remaining issue or evidence gap.

20-MINUTE WALKTHROUGH

We walk it before the call.

Choose one checkout, sign-up or cancellation flow. We review it before the call so we can focus on what matters.
