How Natural Cycles used TikTok’s automated performance solutions to scale efficiently through peak season.

Natural Cycles is a women’s health company best known for its FDA-cleared birth control app, helping users track fertility through daily temperature data and wearable integrations. As Q4 moved into the high-intent Q5 season, the brand saw a clear opportunity to meet rising demand while keeping acquisition efficient across web and app journeys.
To make that growth moment count, Natural Cycles put TikTok’s automated performance solution Smart+ at the center of the campaign. With machine learning, purchase signals, and native-feeling creative working together, the campaign delivered an 8.1% improvement in ROAS and an 8.4% reduction in Cost per Purchase when comparing the pre-Q5 and Q5 periods.
For Natural Cycles, peak season was about scaling with discipline. The brand wanted to capture demand, improve ROAS, reduce acquisition costs, and support sustainable purchase and subscription growth.
The Q4 to Q5 period brought the kind of conditions where performance strategy matters most: rising intent, tighter budget expectations, and a need to move audiences closer to action. TikTok’s automated performance solutions gave Natural Cycles a way to respond to that momentum while keeping efficiency at the core.
The campaign also supported a more balanced acquisition strategy. By connecting native creative with TikTok’s conversion-focused products, Natural Cycles could turn discovery into purchase intent without losing sight of cost control.
Natural Cycles built its TikTok strategy around lower-funnel performance. Web campaigns were optimised for purchases and subscriptions, while app campaigns focused on installs, helping the brand guide people toward the most relevant next step.
At the center was Smart+, TikTok’s automated performance solution. Smart+ helped automate budget allocation across placements and creatives, while TikTok Pixel and Events API supplied the conversion signals needed to optimise toward purchases and subscriptions.
Creative carried the same performance mindset. Through In-Feed Ads and Spark Ads, Natural Cycles brought organic-style storytelling into the native TikTok environment, including an Oura Ring integration with the message “Wear your ring overnight,” a simple product moment that felt made for the platform.
The campaign delivered where it mattered most. Comparing the pre-Q5 and Q5 periods, Natural Cycles achieved an 8.1% improvement in ROAS and an 8.4% decrease in Cost per Purchase, strengthening efficiency during a demanding seasonal window.
The performance came from TikTok’s automation, conversion signals, and native creative working together. Smart+ helped the campaign respond as demand shifted, while TikTok Pixel and Events API supported the measurement foundation needed to optimise toward action.
The learnings are now shaping the next phase of the partnership, as Natural Cycles continues to explore incremental impact, scale responsibly, and use TikTok’s performance solutions to support efficient growth.
TikTok is a meaningful contributor in our channel mix. At Natural Cycles, we're focused on validating incrementality initiatives and scaling responsibly while maintaining efficient CPAs.
