Ona: AI Cycle Expert & Tracker is a simple AI‑powered tool that helps women understand their cycle and hormonal symptoms. The app has been on TikTok since 2024, but only at the end of 2025 and early 2026 did its first real hits start to appear.
Most of the traction is coming from two accounts, @lena.ona.app and @pcosbestie1, both run by the same creator.
Their strongest videos are slideshow‑style posts showing anxiety‑driven situations many women relate to.
“rare aesthetic: pregnancy paranoia” → 4.1M Views
The video with the highest number of comments features the creator sharing the story time of when she got her first period.
“when I was 13 I had my 1st period”-> 1.3M views, 9,415 comments
This “raw confession” style is similar to what we saw with Musa app.
1.2M views
Hook: “10 years of using a male‑designed period app and now I find this…”
Musa consistently includes a clear CTA at the end of each video, which contributes to its 70K+ downloads, while Ona remains under 5K.
Another strong format for Ona was an educational video, which reached 2.5M views.
“how much bl00d we think we lose every period”
This aligns with the educational strategy used by Aavia: Cycle Symptom Relief, which built an entire library of women’s‑health hooks.
A few examples:
“Women’s health fact they don’t teach you in school 👇”
“Your pain tolerance is actually highest right after your period.”
“Your period isn’t just blood — it’s your uterus shedding actual tissue.”
Aavia’s videos rarely go beyond 500K views, but they consistently mention the app clearly, and that is something Ona still does not do.
Right now, Ona has virality, relatability, and strong creator storytelling. What it still needs is consistent attribution, which is key if they want to turn views into downloads.
