Business Context

Innertune is an affirmations listening app designed to help people build better mental habits. The founder had a clear vision but needed to move fast: validate the concept, ship a polished product, and learn from real users before committing to scale.

Most mobile apps fail because they build too many features without understanding their users. Innertune's leadership wanted the opposite approach: start lean, measure everything, and let user behavior drive the roadmap.

The hardest part of building a consumer app isn't the technology. It's knowing what to build first and what to ignore.

Challenge

The core tension was speed versus quality. Innertune needed to:

• Launch a functional, polished iOS app fast enough to validate the concept before funding ran thin
• Build analytics into the foundation from day one, not as an afterthought
• Design the architecture so the same codebase could expand to Android without a rewrite
• Support offline listening and caching without compromising the user experience
• Maintain App Store quality standards that would drive organic growth through ratings

The founder needed a technical partner who could own the product thinking alongside the engineering, not just execute a spec.

Approach

Kunso embedded as the product and engineering core. Not a vendor building to requirements, but a team that co-owned the outcome from concept through scale.

Phase 1: Discovery and MVP (9 Weeks)

The first three weeks were dedicated to discovery: mapping user roles, defining the critical flows, and making the architectural decisions that would determine whether the app could scale later without a rewrite.

The remaining six weeks were pure execution. A lean team of one senior engineer and one product lead shipped a fully functional MVP to the App Store. The goal was simple: get the app into real hands and start learning.

Phase 2: Scaling (Ongoing)

Once traction was visible, the focus shifted to growth infrastructure:

• Cross-platform expansion using Flutter to serve both iOS and Android from a single codebase, cutting development effort by 50%
• Behavioral analytics with Amplitude, embedded deep enough to track retention drivers and inform every product decision
• Revenue optimization through web checkout flows that captured traffic beyond the app stores
• Backend migration from Firestore to PostgreSQL, replacing early-stage tooling with infrastructure that could handle a growing user base

Every decision was tied to a measurable outcome. No feature shipped without a clear hypothesis about what it would move.

Impact

Innertune went from idea to live product in under seven weeks. Within eight months, the app had 200,000 users. Within the first year, it generated $500,000 in revenue with a 15.5% free-to-paid conversion rate and a 4.9 average App Store rating.

The same lean team has been working together for over four years, scaling the product past one million users without the churn and handoff costs that come with traditional outsourcing models.
