TL;DR

Safety Checkpoint is a post-surgery check-in app for the weeks you spend alone at home. A recurring protocol asks for one tap at the time you choose each day, and your family gets a short email each time you tap. If a tap does not come, they are alerted within minutes. With their PIN, they open the message you wrote, with your surgery, your medications, your door code and your surgeon's number. Stop it when you are back on your feet. A daily check-in is a recurring protocol, on Safety 101 and above.

Who is this for?

People recovering at home after surgery, hospitalization, or injury, particularly those who live alone or whose caregiver is absent during part of the day. Also useful for family members coordinating post-discharge care remotely.

Why Is the Post-Discharge Period So Dangerous for Falls?

Hospital readmission within 30 days affects roughly 1 in 5 Medicare patients in the U.S. Falls are a real risk during home recovery, especially after orthopedic surgery, cardiac procedures, or any intervention that affects mobility.

During this temporary but critical period, a check-in gives you a structured safety net for the weeks of recovery.

In a study of 267 older adults in Australia, 41% fell in the year after knee replacement surgery, with the highest fall rate in the first month (Am J Phys Med Rehabil, 2022).

How Do Temporary Check-in Protocols Protect Recovery Patients?

Run it for the weeks you need

A recurring protocol has no end date: it runs every day until you stop it. Pause it on the days a caregiver is with you, resume the next morning, and stop it for good when you are steady.

Two protocols early, one later

A protocol asks for one tap per day. For the first critical days, run two, morning and afternoon. When you are steadier, stop the afternoon one. A running protocol cannot be edited, so tapering means stopping one, not changing it.

Include post-op details

Your alert message can include the info relevant to anyone checking on you: surgery type, medications, mobility restrictions, and doctor contact.

How Does a Recovery Check-in System Work?

  1. Check-in reminder before the scheduled time

    You receive a reminder 15 and 5 minutes before the hour you chose (e.g. 10 AM, and 3 PM from a second protocol), by email everywhere and as a push notification in the iPhone app (in beta). Tap to confirm you're okay, and your contacts get a short confirmation email.

  2. Missed time reached

    If you don't respond, the server marks the check-in missed within a couple of minutes. A reminder comes before the time. There is no separate buffer on a daily protocol. Only one-off protocols can hold the alert for a delay you set, up to 48 hours.

  3. Contacts alerted by email, SMS on Survival

    All designated contacts are alerted at once, from our servers, whatever your phone is doing. With their PIN, they open your pre-written message, including post-op details and access instructions.

Frequently asked questions

Short answers first. Each one links to where the detail lives.

What check-in app should I use while recovering at home after surgery?

One that asks for a tap and fires on silence. Safety Checkpoint runs a recurring daily check-in. You tap at the hour you chose and your family gets a short email. Miss it, and within minutes they are alerted and use their PIN to open the message you wrote, with your post-op details and access instructions. No pendant, no hardware, nothing to wear.

More detailLess detail
  • Set up in a few minutes. The message carries surgery, medications, mobility, door code, surgeon
  • Contacts need no app: email on every plan, SMS as well on Survival
  • The alert comes from the server, so it works after a fall with the phone on the counter
  • Pause on the days someone is with you, and stop it when you are back on your feet
  • A daily check-in is a recurring protocol, on Safety 101 and above

Is there a free check-in app for recovery after surgery?

Not for a daily routine: Safety Checkpoint's free plan, Safety Base, is one one-off protocol a month with one contact, enough to test the alert your family would receive. A daily check-in over several weeks is a recurring protocol on Safety 101, which also allows up to 10 contacts.

More detailLess detail
  • Safety Base: 1 one-off protocol a month, 1 contact, unlimited email alerts, to try the chain once
  • Safety 101 ($4.99/mo): recurring daily check-ins, up to 10 protocols, 10 contacts, unlimited emails, an audio recording in your package that your contacts can hear
  • Survival ($9.99/mo): SMS delivery, unlimited emails
  • Subscribe for the month of recovery and cancel after. There is no contract
  • The confirmation emails your contacts receive at each tap are never counted, on any plan

How long should I use a check-in system after surgery?

Run it for your first weeks at home, and stop it once you trust your mobility again. The protocol has no end date: it runs until you stop it.

More detailLess detail
  • After a knee replacement, falls are most frequent in the first month home (Am J Phys Med Rehabil, 2022)
  • After a knee replacement, the NHS suggests trying to walk without a walking aid after about 6 weeks
  • Follow your surgeon's guidance and how your recovery actually progresses
  • Common mistake: stopping too early because you feel fine, then having a setback alone

Can I adjust the check-in as I heal?

By pausing, stopping and creating, not by editing: a running protocol cannot be changed. Run two protocols early, morning and afternoon, and stop the afternoon one when you are steadier. Pause the remaining one on days a caregiver is present, and stop it for good when you are back on your feet.

More detailLess detail
  • One protocol asks for one tap per day, so twice daily means two protocols
  • Taper by stopping the afternoon protocol, not by editing it
  • Pause and resume from the app on caregiver days
  • A setback later: create a new protocol in a few minutes. The message can be pasted from the old one
  • Keep it running on good days too, because setbacks are unpredictable

What should I include in a post-surgery alert message?

Everything the person who reads it would need to help you: surgery type and date, current medications, mobility limitations, home address, access instructions (door code, spare key), and your surgeon's contact.

More detailLess detail
  • Surgery type and date (e.g. 'right knee replacement, March 5')
  • Current medications with dosage and timing
  • Mobility status (e.g. 'uses walker, cannot climb stairs')
  • Home access details: door code, spare key location, building entry
  • Surgeon and primary doctor phone numbers for medical decisions

Is a recovery check-in app better than a medical alert pendant?

Different jobs. A pendant is for the moment you can press it. A check-in is for the moment you cannot, or forgot to. For a few weeks of recovery, a check-in needs no hardware, carries the post-op context a call center does not have, and reaches the people who can come. For a permanent need, a pendant with fall detection is the better long-term tool, and both can coexist.

More detailLess detail
  • No device to wear, charge, or remember to put on each morning
  • Your message includes post-op context a monitoring center would not have
  • Family or a caregiver can respond faster than a call center for non-911 situations
  • Safety Checkpoint alerts your people but does not call emergency services
  • Medical alert pendants remain the better fit for ongoing, permanent monitoring

Set up a recovery check-in

A daily tap for the weeks you are alone at home. Your family hears it, and if it stops, they are alerted and open your message. Create it in a few minutes, stop it when you are ready.
