Spotify leads with "£0" and spells out the price after

The psychology

Why it nudges

Spotify uses the zero-price effect: £0 is treated as categorically different from a small price. The trial also relies on the status quo, because Premium continues at £12.99 a month unless you cancel. Results are not public.

Context

A consumer music subscription marketing to UK listeners who haven't tried Premium. The aim is likely to build a listening habit during the trial before billing starts.

Honest nudge or dark pattern?

Conditional

Honest nudge if the renewal price and how to cancel are shown at sign-up. Without them it becomes a hidden subscription. See deceptive.design/hidden-subscription.

Steal this, honestly

Write the offer as "£0", not "free trial", where it fits.
Put the price after the trial in the same block as the offer.
Make the trial long enough for the habit to form.

What to test: "1 month for £0" vs "2 months for £0". Measure conversion to paid at the end of the trial and 6-month retention.

Next: run it on your product

Pattern: Spotify: Spotify leads with "£0" and spells out the price after
Bias: Zero-price effect: 'Free' is treated as more than just a lower price.
Why it nudges: Spotify uses the zero-price effect: £0 is treated as categorically different from a small price. The trial also relies on the status quo, because Premium continues at £12.99 a month unless you cancel. Results are not public.
Our verdict: Conditional. Honest nudge if the renewal price and how to cancel are shown at sign-up. Without them it becomes a hidden subscription.

Rules: say a brand "uses" a tactic, never that it "worked"; outcomes are not public unless the company published them; no invented uplift estimates; flag mixed evidence. Honest nudge = true, visible, easy to reverse, and in the user's interest. Dark pattern = hides costs, fakes scarcity or popularity, shames, or makes leaving harder than joining. Quote company-published results as "X reports", with the source link, and don’t generalise them. Don’t cite retracted or failed-to-replicate studies as support (e.g. Ariely & Wertenbroch 2002). Don’t state study figures unless they’re on this page or in a source you can link. If an idea crosses the line, link the matching deceptive.design pattern.

Tasks:
1. Ask me for my product, the flow (URL or screenshots) and the goal.
2. Audit where this pattern already appears, or could, in that flow.
3. Propose 2-3 ethical experiments: hypothesis, variant copy or UI, primary metric, and a guardrail metric (refunds, complaints, cancellations).
4. Flag every dark-pattern risk and say how to stay on the honest side.

ChatGPT, Claude, Grok and Cursor open with the prompt filled in (it is also copied, in case the prefill doesn't load). Gemini and Codex don't support prefilled links, so the prompt is copied and the app opens; paste it in.
