DavaNinja

I helped DavaNinja design a medicine delivery experience that keeps users coming back.

DavaNinja, a 1-hour medicine delivery service in Mumbai, faced 3 key challenges:

1. An app built for acquisition, not repeat purchase or CLTV

2. Complex fulfilment realities (split delivery, out-of-stock) that were creating friction and drop-off

3. No proactive reordering support for chronic patients

The product needed to evolve from a transactional delivery app to a trusted health companion for everyday medicine needs.

We redesigned the experience across four critical surfaces:

1. Rebuilt the homepage for CLTV - surfacing personalised offers, reorder shortcuts, and loyalty incentives for repeat users instead of treating every visit like a first-time acquisition.

2. Designed the split delivery flow - where orders are fulfilled across multiple pharmacies — in a way that felt reassuring rather than confusing, with clear visibility into what's coming from where and when.

3. Designed an out-of-stock experience that converts rather than abandons — surfacing alternatives, notify-me options, and partial fulfilment paths to keep the user in the funnel.

4. Built a proactive subscription feature for chronic patients, auto-scheduling refills before medicine runs out.

This repositioned DavaNinja from a utility app to a proactive health platform — one that anticipates patient needs rather than just fulfilling them.

The Business Impact

• Built a homepage experience optimised for repeat purchase and long-term engagement

• Reduced drop-off at critical friction points: out-of-stock moments and split deliveries

• Created a retention layer for high-frequency users through subscriptions and reorder shortcuts
