If you are switching from another cycle app, you can bring your history into Mela in one step, so years of logs come with you with no re-entry.

PRIVACY BY ARCHITECTURE Many cycle apps keep your data on their servers, behind a policy promise. Mela is built differently: no server, no analytics SDK, no advertising network. Your data is stored only on your iPhone, with iOS file protection, so even other apps cannot read it. Mela cannot leak what it does not collect, because the data never leaves your iPhone. LANGUAGES English and Russian. REQUIREMENTS iPhone, iOS 17 or later. TERMS OF USE https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ PRIVACY POLICY https://nlarionov.github.io/mela-privacy/ Mela is not a medical device and is not contraception. Predictions are estimates from your own data, not medical advice. For medical decisions, talk to a clinician.

The clearest difference is in-app purchases: CycleSync at none against Mela's 3. CycleSync also leads on update cadence (every 2 days vs every 9 days). On price, ads, device support and iOS requirement there is nothing between them.
