Eight-week home walking and breathing programme for COPD, with a finger oximeter
TL;DR Lungstride runs pulmonary rehabilitation at home for people with COPD. A chest physician prescribes it, the patient gets a finger oximeter and a step counter, and a physiotherapist guides graded walking and breathing exercises by video for eight weeks. Patients or their families pay, through the clinic. Almost nobody in India gets this care today.
India has the second-largest number of people in the world who could benefit from COPD rehabilitation, about 24.6 million in 2021[1]. Pulmonary rehabilitation, a supervised course of exercise and breathing training, is standard care abroad. In India it barely exists outside a few teaching hospitals. Doctors at AIIMS Jodhpur write that distance, cost and limited availability keep centre-based programmes out of reach for most patients[2].
So what do most patients get? Inhalers and not much else, so they grow breathless and stop walking and lose muscle, which only makes them more breathless.
What it does, in regulatory terms - supervised exercise therapy by registered physiotherapists, using a licensed pulse oximeter for safety readings. It does not diagnose, adjust medicines or claim to treat COPD itself. Pulse oximeters are medical devices, so buy only CDSCO-licensed models[3].
The chest physician refers the patient. A physio runs a first video session to set safe walking targets, then the patient walks and does breathing drills daily. They log oxygen saturation and heart rate before and after, and step counts sync on their own. If saturation drops below a level the doctor set then the app tells the patient to stop and alerts the physio. Twice a week the physio calls and raises the targets, and at the end a short report goes back to the doctor.
Do home programmes work? A 2026 network meta-analysis of 39 trials found telerehabilitation, home-based and hybrid rehab all improved walking distance and quality of life over usual care, though evidence certainty was low[4].
The patient benefits and the family usually pays, as they already do for inhalers and nebulisers. Chest physicians and hospital pulmonology departments refer patients and may resell the programme under their own name. I found no public price for home pulmonary rehab in India, so test price points directly. Insurers and employer health plans are a later buyer.
The NCAHP Act of 2021 brought physiotherapists onto formal registers[5], which gives doctors a clear professional to refer to. Licensed finger oximeters became household items after 2020, so nobody needs a lesson on clipping one on. AIIMS Jodhpur authors now call for home rehab to be built into national respiratory programmes[2].
Nobody has a figure for India's pulmonary rehab spending. The narrowest number is the 24.6 million people with a potential rehab need[1].
You don't need anywhere near that to test the business - a few thousand paying patients a year in two cities, referred by a dozen chest physicians, is plenty.
One UK digital programme offers a full pulmonary rehab programme at home, plus inhaler videos and clinician dashboards, and cites a trial showing it was no worse than face-to-face classes[6]. In India, a few teaching hospitals run centre-based or research programmes like AIIMS Jodhpur's[2]. I found no Indian company selling home pulmonary rehab through chest physicians, though my search was limited.

The app is simple. The hard parts are getting chest physicians to refer and keeping elderly, breathless patients exercising for eight weeks, and then hiring physios trained in respiratory care. Safety rules for when to stop exercising must be written with doctors before the first patient starts.
Yes. The service runs on registered professionals and licensed devices.
Building this outside India? The categories above usually have a local equivalent, so check with your own regulator.
Don't let AI set or raise exercise targets, or decide when a low oxygen reading is safe. The doctor sets the stop level and the physio makes every change.

Here's what can go south -
I think this is a practical idea for a founder with a respiratory physiotherapy or pulmonology background. It's a poor fit if you want a pure app.
Prove two things first - that ten chest physicians will each refer five patients a month, and that 60% of patients finish all eight weeks.
Plan for roughly ₹50 L–1 Cr, mostly on physiotherapists, licensed oximeters and doctor outreach.
Your physiotherapists must be registered under the NCAHP Act, oximeters must be CDSCO-licensed, and doctors handle any medicine advice. You also need DPDP consent.
Yes, COPD is common worldwide and home rehab has trial evidence. Check local rules on physiotherapist registration and remote care first.

Thinking about building Lungstride or something close to it? The make-or-break work is winning steady referrals from chest physicians and keeping breathless patients going for eight weeks, and I'm glad to work through that with you. If you need a hand, you know where to find me. Talk to Yash →
