Tidalflow

What is Tidalflow?

Tidalflow is an Amsterdam AI health company whose current product is Lila, a perimenopause nutrition coach for iPhone. The app links what you eat with symptoms such as hot flushes and poor sleep, then suggests changes.

Lila works through quick daily inputs. You photograph a meal, record how you feel, and an AI coach looks for patterns between food and symptoms before offering recipes, meal plans or supplement ideas. The App Store listing says the app was built with Rebecca Rumsey, a registered dietitian, and is aimed at women over 40. Lila states that it does not give medical advice, so treat its suggestions as general wellness guidance.

The company has pivoted twice. Sebastian Jorna, Coen Stevens and Henry Wynaendts raised $1.7 million in October 2023, led by Gradient Ventures and Dig Ventures, for a platform that helped software firms build and monitor plugins for large language models. It then ran a WhatsApp AI personal trainer that directories still describe. Its homepage now presents a women’s health business linking only to Lila, sold under the name NerveCenter.ai BV.

Key Features

Photo meal logging and symptom tracking let Lila’s coach connect each meal with how you felt afterwards.

• Photo meal logging: You photograph a meal and the app estimates its contents instead of asking you to weigh food. Mergeek’s listing adds that it tracks macros, fibre and water against menopause-related weight goals.
• Symptom tracking: The app records more than 20 symptoms, including night sweats, brain fog, bloating, joint pain and mood. Logging them daily gives the coach enough data to spot links with particular foods.
• AI chat coach: A chat assistant answers nutrition questions at any hour and suggests hormone-friendly swaps. Reviewers on the App Store often say it understands perimenopause better than general diet chatbots.
• Daily Peri Score: A daily score summarises how your food choices may have affected symptoms such as hot flushes, sleep and mood. It comes with short practical tips after meals rather than a long report.
• Meal plans and recipes: Lila builds personalised meal plans with custom recipes, a feature added in 2025 updates. Plans sync with the tracker, so logged meals and planned meals sit in the same view.
• Weight trends and supplements: Weekly weight trends replace daily swings, which can be discouraging during hormonal change. The app also suggests supplements based on gaps it detects, so check these with a pharmacist or doctor.

Pros

Perimenopause is Lila’s narrow focus, shaping its symptom list, recipes and coaching around women over 40.

• Clear focus: Lila is built for perimenopause rather than generic dieting. Women who found calorie apps ignored hot flushes, sleep and bloating get tools designed around those problems.
• Quick logging: Photo entries take seconds and need no food scales or barcode scanning. Busy users are therefore more likely to keep logging every day, which the symptom analysis depends on.
• Strong app rating: The App Store shows 4.7 stars from about 1,700 ratings in October 2026. Many reviewers praise the coach’s supportive tone and its grasp of midlife symptoms that general apps miss.
• Dietitian input: The App Store listing names registered dietitian Rebecca Rumsey, MSc, as a contributor to the app. That gives its advice more grounding than apps that rely on a general chatbot alone.
• Apple Health link: A 2025 update added Apple Health integration, according to the version history. Users who already track activity or weight on an iPhone can bring that data in.

Cons

Lila’s biggest drawback is that it runs only on Apple devices, so Android and web users cannot use it at all.

• Apple only: There is no Android app or web version of Lila. Android users need an alternative such as Balance or Caria, and households with mixed devices cannot share one tool.
• Unclear plans: The App Store lists prices from $5.99 to $464.99 without clear plan names. You only see what each option includes on the subscription screen inside the app.
• Ad tracking: Apple’s privacy labels say usage data is used to track you, and health and sensitive data can be linked to your identity. Privacy-minded users should read the policy before logging symptoms.
• Logging accuracy: Some App Store reviews report different calorie counts for the same meal and repetitive suggestions. The developer has replied with bug fixes, but you may need to correct entries.
• Unproven claims: The listing says 72 per cent of women lose weight within two weeks, a company figure we could not verify. Treat such results as marketing rather than clinical evidence.

Who is Using Tidalflow?

Lila is used mostly by women in perimenopause who want food advice tied to their symptoms rather than calorie targets alone.

• Women in perimenopause: Women over 40 log meals and symptoms to see which foods affect hot flushes or sleep. They then adjust their diet using the coach’s suggestions.
• Midlife dieters: People whose usual diets stopped working during hormonal change follow Lila’s meal plans. Weekly trends help them judge progress without daily weigh-in stress.
• Busy professionals: Working women log meals by photo between meetings. The quick check-in fits a crowded day better than manual food diaries.
• Former WhatsApp users: Some earlier customers of Tidalflow’s WhatsApp fitness coach meet the company again through Lila. Directories still list that older service, which can cause confusion.

Pricing

Lila is free to download, with paid in-app purchases from $5.99 up to a $464.99 lifetime option (App Store listing, checked October 2026).

Directories conflict: Toolify says freemium, The AI Report quotes from $40 a month, and a legacy tidalflow.com page shows the trainer at $5.99 a month, billed annually.

App Store prices vary by country, so confirm on your device first.

What Makes Tidalflow Unique?

Lila’s daily Peri Score ties each meal to the symptoms you logged that day. Linking food to symptoms, rather than counting calories alone, separates it from mainstream diet apps such as MyFitnessPal or Noom.

The company’s own path is unusual too. Few health apps come from a team that started by building infrastructure for large language model plugins, then tried WhatsApp coaching before settling on women’s health. That background shows in the chat-first design, and it suits women who find that calorie trackers do not explain their symptoms.

Compatibilities and Integrations

Lila runs on Apple devices only and connects to Apple Health, with no public export or third-party API.

• Platforms: iPhone and iPad on iOS 15.1 or later, Apple silicon Macs and Vision Pro.
• Health data: Apple Health integration was added in a 2025 update, according to the App Store version history.
• Messaging: The earlier personal trainer used WhatsApp, but Lila works inside its own app.
• Data: Meals, symptoms and weight stay in the app, with no public export option.

How We Rated It

Tidalflow gets 3.6 because Lila is easy to use and well focused, while privacy labels and unclear pricing hold it back.

Summary

Tidalflow, through Lila, suits women in perimenopause who want food advice linked to their symptoms. The main limitations are the Apple-only app and in-app prices without clear plan names. Its health claims come from the company, and the app is not a substitute for medical advice, so talk to your doctor about persistent symptoms. Try the free download first and check the subscription screen before you commit.
