Bloom is a private fertility and cycle tracker that uses the symptothermal method. Everything you log stays on your iPhone.
Email support@yuzi.nl and we will get back to you.
Where is my data stored? Only on your device. Bloom has no account, no cloud sync, and no network connections. See our Privacy Policy.
What is Bloom Pro? A one-time purchase that unlocks on-device AI features (natural-language logging and plain-English cycle insights) and data export. Pay once, no subscription. The AI runs entirely on your iPhone.
Why don’t I see the AI features? They need an Apple-Intelligence-capable iPhone (15 Pro or newer) running iOS 26 or later, with Apple Intelligence turned on. Without that, the rest of Bloom still works.
Is Bloom birth control? No. Bloom is a tracking and education tool. It is not a medical device and makes no contraceptive-efficacy claims. Talk to a healthcare provider about decisions on conception or contraception.
