Know Mum is okay, wherever you live.
Lasna connects to the Apple Watch your mum already wears.
You see how her day is going from your own phone.
If she falls and does not answer her watch, or is not up by her usual time, your whole family hears at once.
Lasna works the same for Dad, a grandparent or anyone who lives alone. Looking after Dad?
Follow Mum's day from your own phone.
These are real screens from the Lasna app. Pick a moment to see what Jane sees in London.
See who is awake right now.
Jane lives in London. John lives in Austin. Ana lives in Singapore.
Lasna sends an urgent alert to all three at once, day or night. It holds gentle notes until each person's morning.
- --:--Mum in Columbus, Ohio
- --:--Jane in London
- --:--John in Austin
- --:--Ana in Singapore
Hear about a bad morning before you call.
Lasna learns when Mum gets up, how long she naps and how far she walks. This takes about two weeks.
After that, Lasna compares each day with her own normal. A late riser gets no alert at eight. An early riser who is still at nine does.
Get urgent alerts for real emergencies
Each alert waits for a clear sign that something is wrong. Then Lasna alerts and texts everyone Mum allows. It calls the family after three minutes if nobody responds. After ten minutes it shows everyone the local emergency number.
- Hard fall
- Her watch detects a hard fall and asks if she is OK. Lasna alerts you when she does not answer within about a minute or says she fell. If she taps I'm OK, you get one calm note instead.
- Fall away from home
- Lasna adds the place where she fell.
- Help pressed
- Mum presses Help on her watch or phone.
- Not up by her usual time
- Her watch and phone see no movement well past her usual wake-up time.
- Missed check-in
- Mum skips the daily I'm fine that she chose.
- Heart notifications

Lasna is a family awareness app. It is not a medical device. It reports what her watch and phone saw. It does not diagnose.
Apple Watch fall detection and Emergency SOS keep working on their own.
Get one calm note after a restless night.
Her watch records her sleep. Lasna compares each night with her last 28 nights.
You hear about a night only when it looks clearly unlike her. The note arrives after she gets up.

- 407:32Up for the day
Lasna, Wednesday 08:10
Mum had a restless night
Mum was awake 1 h 20 min in the night. She is usually awake for 15 minutes. She got up twice for longer spells, at 1:30 and 4:10. She started her day at 07:32, her usual time.
Lasna sends this note once. It never rings and never escalates.
Lasna, Wednesday 10:00
Mum may be coming down with something
- Wrist temperature
- +0.6°C
- Resting heart rate
- +5bpm
- Breathing rate
- +1.6/min
Lasna compares each number with her own 28-night normal. All three rose together overnight. That is a good reason to call and ask how she feels.
Lasna does not diagnose. Sleep notes need Mum to wear her watch to bed with sleep tracking on.
Mum chooses what each of you sees.
You set up Lasna with Mum, on her own phone. She decides what each person can see.
She can see who looked at her day. Every change she makes reaches the family at once.
Mum picks a level for each person
She chooses Safety only, Safety and wellbeing, or Everything. She can fine-tune each category, such as location.
Mum previews what Jane sees
She opens Jane's view with today's real data. Anything that Jane cannot see stays private.
Mum pauses sharing
She pauses sharing for an hour, three hours or until the morning. Her safety alerts stay on.
Lasna keeps Mum's raw data on her phone.
Lasna runs every check on Mum's own iPhone. It uploads a short account of her day.
The heart rate samples, motion and location history behind that account stay on her phone.
- 1
Her watch
Her watch detects falls and heart events. Apple's own safety features keep working as before.
- 2
Her iPhone
Lasna learns her routine and runs every check on her phone. It keeps heart rate samples, motion and location history there.
- 3
Lasna's servers
Lasna receives events and a daily summary, such as up at 07:32. It sends each person only what Mum allowed.
- 4
Your phone
You see her day and get alerts within Mum's rules. Mum sees each time you open her day.
Set up Lasna for Mum from wherever you live.

Mum pairs her watch
Mum opens Lasna and types the code. She chooses who sees what. She never needs a password.

Invite your siblings
You share one link. Your siblings join the same circle and agree who calls first.
Mum needs an Apple Watch Series 4 or later and an iPhone. You and your siblings can use an iPhone or an Android phone.
Compare Lasna with a pendant alarm and the watch alone.
| Pendant alarm service | Apple Watch on its own | Apple Watch with Lasna | |
|---|---|---|---|
| What she wears | A pendant or wristband | Her Apple Watch | Her Apple Watch |
| Hard fall detection | On some plans, often for an extra fee | Yes | Yes. The whole family sees the alert |
| Who hears first | A call centre | Emergency services, then a text to her emergency contacts | Every family member at once, with who is responding |
| Notices she is not up yet | No | No | Yes, against her own routine |
| Sleep, illness signs, walking | No | On her own watch and phone | Shared with the people she chooses |
| Family abroad | Phone calls | Text messages | Alerts in every time zone and one shared view |
| Cost | A monthly fee, plus devices | Included with the watch | £17 a month for the family |

Care team
For your family and Mum's home care provider
Invite a nurse, a carer or a neighbour. Mum approves their access. Their access ends on a date she sets. We plan to add this plan after launch.
Prices are proposed launch prices. Setting up is free. Your 7-day free trial starts when Mum's watch connects. The person who sets up Lasna pays through the App Store or Google Play.
Check how ready your family is if Mum needs help.
Answer a few short questions about Mum from wherever you live. If she is active, you get a family plan. If she is slowing down, the check adds the CDC's STEADI fall-risk questions.
You get a plain summary to share with your siblings. You do not need an account.
Get answers before you join.
Does my parent need an iPhone?
Yes, for now. Lasna runs on your parent's Apple Watch and iPhone. Family members can use an iPhone or an Android phone.
What if Mum's watch has no mobile plan?
Her watch sends most alerts through her iPhone. Away from her phone, the watch sends urgent alerts over a known Wi-Fi network. With no connection at all, Lasna's servers notice the silence and tell you they lost contact.
Does Lasna replace Apple's fall detection or Emergency SOS?
No. Apple Watch still calls emergency services on its own when Mum does not respond after a hard fall. Lasna adds the family. Everyone hears at once and sees who is responding.
Will a stumble or a dropped watch set off an alarm?
No. After a hard fall, her Apple Watch first asks whether she is OK. If she taps I'm OK, the family gets one calm note and nothing escalates. Lasna raises the alarm only when she does not answer, says she fell or presses Help.
Will it drain her watch battery?
Lasna runs no sensors of its own on the watch. It reads what the watch already measures. It wakes only when something happens.
What happens when she takes the watch off to charge?
Lasna expects her to charge the watch and sends no alert for that. If she leaves the watch off during the day, Lasna reminds her first. Then it lets you know.
Can Lasna call emergency services?
No. Lasna alerts the family, sends texts and places automated calls to the people Mum chose. If nobody responds, Lasna shows everyone the local emergency number and her last known place. Apple Watch itself can call emergency services.
Who can see my parent's data?
Only the people your parent approves can see it. She sets a level for each person. Lasna keeps raw heart rate, motion and location history on her phone. She can pause sharing and see who opened her day.
Is Lasna a medical device?
No. Lasna is a family awareness app. It reports what her watch and phone saw. It does not diagnose or give medical advice.
