Mendtide 1.2: Widgets, Smarter Notifications, and Five New Health Signals

Mendtide 1.2 brings home screen and Lock Screen widgets, notifications that only fire when they matter, and five new Apple Health signals — hydration, mood, mindfulness, blood oxygen, and wrist temperature.

Mendtide 1.2 is out today. It is the biggest update since launch, and it is built around one idea: your sleep context should follow you — to your home screen, your Lock Screen, and into every conversation with the coach.

Here is what is new.

Home screen and Lock Screen widgets: your sleep summary without opening the app

The two most common questions Mendtide users ask in the morning are “how did I sleep?” and “how much is my sleep debt right now?” Starting with 1.2, both are answered before you unlock your phone.

Four new widgets ship with this release:

The Morning Plan widget surfaces the top recommendation from your daily briefing directly on your home screen — the one thing the coach thinks matters most today, based on last night and your recent pattern.

The Sleep Debt widget shows your current 14-day rolling deficit in the same calm mauve the app uses. No red. No alarm-clock iconography. Just the number, and whether it shifted.

Two Lock Screen widgets give you a fast read at glance height: last night’s total sleep and your longest unbroken stretch. The stretch number is the one Mendtide has always treated as first-class — because a 7-hour night in five fragments is a different biological event than 6 hours straight, and that difference should be on your Lock Screen, not buried three taps in.

All four widgets are built in calm mauve. None of them ever use red.

Smart notifications: alerts that earn their place

Most apps solve the notification problem by letting you configure a pile of toggles and hoping you pick the right ones. Mendtide takes a different approach in 1.2: the system decides whether a notification is worth sending, and it sets a high bar.

Sleep debt shift alerts fire only when your 14-day debt changes by one hour or more compared to the same period last week. That threshold is intentional — a single rough night is normal variation, not a trend. A one-hour shift over a two-week window is a signal worth acting on. When it fires, it tells you whether the trend moved up or down, not just that something changed.

Frequency cap: at most once per direction per week. You will not get a “your debt is going up” notification every day during a bad stretch. You get one, you decide what to do with it, and the system stays quiet until the direction actually reverses.

Quiet hours: no pings between midnight and 5am. The 3am module exists for those hours. Notifications are not part of it.

In-app blog notifications: when a new article publishes, you will get a notification that opens it directly inside the app. Native reader, no browser, no ads.

The Trends tab gains a new Wellbeing section in 1.2, pulling five signals from Apple Health that none of the other sleep trackers connect back to your nights.

Hydration (water logged and timing). Dehydration is one of the underappreciated contributors to sleep fragmentation and morning fatigue. The card shows your daily totals and flags whether you are hitting the baseline that the research on overnight recovery typically references.

Mindful minutes (from Apple Mindfulness). Consistent mindfulness practice has a measurable effect on sleep onset and REM quality in the peer-reviewed literature. If you are logging time in Calm, Headspace, or the native Breathe app, Mendtide now sees it and the coach can factor it in.

Mood (from Apple State of Mind). Emotional state and sleep are bidirectional — poor sleep degrades mood, and negative mood increases arousal at bedtime and suppresses slow-wave sleep. Apple’s State of Mind entries now flow into your Mendtide context so the coach can distinguish a genuinely rough night from a rough day that followed you to bed.

Overnight blood oxygen (nightly mean from Apple Watch). Blood oxygen is one of the primary signals clinicians use to screen for breathing disruptions during sleep. Mendtide does not diagnose — it shows you your nightly mean and flags significant dips with a press-and-hold research note, the same way every other metric works in the app.

Sleeping wrist temperature (deviation from personal baseline). Temperature deviation is where the Apple Watch’s sensor advantage is clearest. A body that runs warm overnight — from illness, ovulation, alcohol metabolism, or perimenopause — tends to get lighter, more fragmented sleep. Your deviation from your own rolling baseline is now a first-class card in Wellbeing, with context on what drives it.

All five cards follow the same freshness rule as every other metric: if there is no recent data, the card does not appear. Press and hold any card to read the research behind it.

The coach sees more

The coach in 1.2 has access to all five new Wellbeing signals alongside everything it already saw: last night’s sleep, HRV, training load, caffeine, alcohol, and — for users who track it — cycle phase.

That expansion matters most in the conversations where context is everything. A question like “why do I feel so off today?” can now get an answer that looks at hydration, mood, overnight temperature deviation, and sleep architecture together, rather than sleep data in isolation.

The model stays the same — claude-haiku-4-5-20251001, fast and on-device-friendly. What changed is how much it knows about you when you start typing.

One note on Blood Oxygen and Temperature data

These two signals require Apple Watch and, for the most accurate overnight readings, watchOS sleep tracking enabled in the Apple Health app. If you have an older Watch or have not enabled sleep tracking, those cards will not appear in Wellbeing until data accumulates. That is expected — Mendtide does not show placeholder cards when there is nothing to show.

Update now

Mendtide 1.2 is a free update for everyone on the 14-night trial or active subscription. Your existing data, history, and context tags carry over completely.

Get the update on the App Store

Sleep context should travel with you through the day — not wait inside an app. 1.2 puts the numbers that matter on your Lock Screen and gives the coach the full picture it needs to help you do something about them.
