Physiotherapy has a completion problem. Most of a programme happens at home, unsupervised, in the days between appointments, and that is exactly where it falls apart. Form degrades with nobody watching. Pain easing gets mistaken for the injury being healed, so people stop early. Nothing and nobody registers that they stopped until the next visit, if there is one.
The people doing this are not the people the fitness-app category is designed for. They’re 30–65, across urban and semi-urban India, with low-to-moderate digital literacy: often exercising one-handed while lying on the floor or steadying a limb, on a mid-range Android, on patchy signal. Every assumption a polished consumer app makes about attention, dexterity and connectivity is wrong here.
