About

A sleep app that tells you what it won’t do.

Mendtide is an AI sleep and recovery coach for iPhone, published by CRMb Industries LLC and live on the Apple App Store since May 2026. It reads the sleep data Apple Health already collects and turns it into a short, calm morning briefing — built specifically for people whose nights don’t fit the textbook: new parents, and women moving through perimenopause.

If you landed here checking whether this is a real product from a real company, the short answer is yes, and everything below is verifiable.

What Mendtide refuses to do

Most sleep apps are judged on what they add. The clearest thing we can tell you about this one is what it leaves out on purpose. These are product rules, not current preferences — they don’t change when growth gets slow.

  • No sleep scores

    No 0–100 number rating your night. Scores invite the exact anxiety that wrecks the next night, and a single number cannot carry the context of a newborn or a hot flash.

  • No red for a bad night

    The interface never turns alarming because you slept badly. You already know it was a hard night. Colour-coding it as failure adds nothing.

  • Nothing scored at 3 AM

    If you open Mendtide in the middle of the night, you get a journal and nothing else. No graphs, no debt counter, no metrics at the hour you are least equipped to hear them.

  • No partner leaderboards

    Sleep is not a competition, least of all with the person next to you. This will not ship, ever.

  • Your data stays yours

    You can edit or delete any night at any time, and your corrections feed back into how the coach reads you. Raw HealthKit samples never leave the device.

  • No ads, no data resale

    The subscription is the entire business model. Nobody pays us to put anything in front of you, and your health data is not a product we sell.

Common questions

Is Mendtide legit?

Yes. Mendtide is published by CRMb Industries LLC, a registered US company, and has been live on the Apple App Store since May 2026 under the listing "Mendtide: AI Sleep Coach". Apple reviews and signs every release. You can verify the publisher yourself on the App Store listing, where the seller name reads CRMb Industries LLC.

Who is behind Mendtide?

Mendtide is built and operated by CRMb Industries LLC. It is a small, independent operation rather than a venture-funded team, which is why the product refuses the growth patterns — streaks, scores, leaderboards — that tend to come with scale pressure. Support reaches a real person at [email protected].

Does Mendtide sell or share my health data?

No. Raw HealthKit samples never leave your device. The AI coach receives anonymized aggregates only — heart-rate-variability ranges, sleep-duration averages, and the context tags you add — never raw biometric samples. There are no third-party trackers, no ad networks, and no data resale. The app carries no analytics SDKs.

How much does Mendtide cost, and is there a free version?

Every new account starts with a 14-night free trial with complete access. After that it is $9.99 per month or $69.99 per year. There is no free tier, no lifetime tier, and no feature gating — every subscriber gets every feature. Nothing is held back for a higher plan because there is no higher plan.

Is Mendtide a medical device, and can it diagnose sleep problems?

No. Mendtide is not a medical device and does not diagnose, treat, or offer specific medical advice. The coach describes what published research says, points to the data behind any numeric claim, and will suggest talking to a doctor when that is the right next step. Anything resembling a diagnosis is out of scope by design.

Where do Mendtide’s recommendations come from?

Every research-backed claim in the app draws from a reviewed pool of 113 real studies, each with a named author, year, journal, and link. The coach cites its sources in chat, and the morning briefing and detail screens do the same. If a claim cannot be sourced, the coach says so rather than inventing a reference.
