Description

The company has more than 500M downloads and over 80M monthly users, and has been building for 10 years while still accelerating.

It is ranked the number 1 health and fitness app worldwide, with a mission to build a better future for female health.

The team is building AI-powered, privacy-first, clinically backed digital health to help users understand their bodies better.

This is a 3-month, full-time freelance contract for a performance copywriter who writes quickly and well on any platform and owns one established focus area, such as Track & Symptoms, including its copy and daily results.

You take copy from concept through production, testing and iteration, working from Creative Strategy briefs, producing many different ideas and adapting each to its platform and funnel.

Responsibilities

• Own the TTC and Pregnancy copy across Meta, Google, Snapchat, TikTok, Pinterest, Moloco and ASO, starting from Creative Strategy briefs and contributing to them.
• Monitor daily results in Looker and refresh any ads losing spend before they stop delivering.
• Write new hooks, angles, scripts and variants each week, each testing a distinct idea rather than rewording a previous one.
• Make sure every ad matches the funnel it leads to, whether web or app, and continues into onboarding.
• Work with designers and motion designers so copy and visuals form one idea.
• Propose new tests, each with a simple hypothesis and the metric that will decide it.
• Use Claude and ChatGPT for variation and summarising results, and Sensor Tower and HookRadar to find angles, editing all AI output critically.
• Write launch and awareness copy for your area with the Brand team, and support social when needed.
• Write compliant benefit messaging before legal and medical review, and give feedback to junior copywriters.

Requirements

• 2-4 years of performance or direct-response copywriting, in-house or at an agency.
• A portfolio of live ads across several platforms, including at least one test showing what won and what you changed next.
• An understanding of how copy and success metrics differ by platform, such as thumb-stop and CTR on TikTok versus conversion on an App Store page.
• Confident daily use of AI tools, with the judgment to recognise output that is not good enough.
• Judgment on health claims and care when writing about personal health topics.
• Native-level English and the ability to explain why a line should work.
• Experience at a health, wellness or subscription app.
• ASO experience.
• Speaking additional languages.

Conditions

The role is fully remote within the UK, and the company also lists a hybrid model with 3 days per week in the office.

The team is mission-led and product-driven, moves fast, stays focused and takes ownership from brief to impact.

Debate is welcome, decisions are shared, and the team cares about craft and raises the bar.

The work takes commitment and resilience, and the team values people who take the work seriously without taking themselves too seriously.

The company is an equal-opportunity employer.
