Most menopause apps tell you what happened.
Give Zero tells you why.

Balance is the best-known menopause app in the UK, founded by GP and menopause specialist Dr. Louise Newson. It has over one million users, an NHS endorsement via ORCHA certification, and a genuinely excellent content library covering HRT, symptoms, and hormonal health. The community is active and well-moderated. Balance+ adds live Q&As with Dr. Newson and deeper content tracks.

What Balance doesn't do is connect your data. It logs what you tell it. It doesn't read your wearable, doesn't interpret your labs, and doesn't generate insight from the intersection of the three. It's an excellent educational and tracking resource, but the intelligence layer isn't there. If your dominant question is “what is perimenopause and am I in it,” Balance answers it well. If your question is “what is driving my symptoms specifically, and what should I do about it,” Balance hands you back a log.

Caria takes a CBT and mindfulness-led approach to menopause, with structured programs for mood, sleep, and anxiety. It has clinical validation and is particularly strong for women whose dominant symptoms are psychological -- stress, low mood, panic, cognitive changes. The content is evidence-based and the programme structure is more guided than Balance's open library.

Caria's limitation is its scope: it's a behaviour-change and mental health tool, not a physiological intelligence platform. It doesn't integrate any external data, and it's not built around the wearable-plus-labs-plus-symptoms model that Give Zero is built on. For women who know their primary challenge is anxiety or sleep-related CBT, Caria is a serious option. For women trying to understand what's happening biologically, it's the wrong category of tool.

Flo is primarily a period and fertility tracker that has expanded into menopause features. With over 280 million downloads globally it's the largest women's health app by a significant margin, and its menopause tracking covers symptoms and cycle changes adequately. It has AI features and integrates with Apple Health.

Two things worth knowing: Flo settled with the FTC in 2021 over allegations of sharing user health data with third parties including advertisers. It has since updated its privacy practices and introduced an “Anonymous Mode.” Whether you trust those updates is a personal decision. The second limitation is that Flo's menopause features feel secondary to its core fertility product -- the intelligence is shallow and the perimenopause-specific content isn't deep.

mySysters is a straightforward US-based symptom tracker with community forums and printable doctor reports. It's useful for women who want a simple log they can share with a clinician and a community of women in similar situations. It doesn't claim to be more than that -- which is honest, and the community element is genuinely valued by its users. There's no AI, no wearable integration, and no lab interpretation.
