Custom-built app: the honest comparison

No dogma: we show when each path pays off, what changes in total cost, and why code ownership decides the product future.

Ownership

Custom app (Tech86)

100% your code, documented, in your own repository

Varies by contract; code sometimes retained

Locked to the platform: no real export

Performance

Custom app (Tech86)

Native or high-performance cross-platform, measured on real devices

Depends on the outsourced team

Limited by the platform runtime

Timeline

Custom app (Tech86)

MVP in 2 to 3 months with sprint deliveries

Long cycles and external schedule dependency

Fast for the simple, stuck on the complex

Total cost

Custom app (Tech86)

Predictable by scope, no recurring per-user license

Billed hours with no clear ceiling

Subscription that grows with usage

Scalability

Custom app (Tech86)

Architecture designed for millions of users from day one

Varies widely; costly future refactoring

Technical ceiling: complex cases unsupported

QA & Testing

Rigorous testing on real devices.

5

Launch

Store publishing and post-launch monitoring.

Frequently Asked Questions about Apps

Everything you need to know before starting.

Native is built specifically for each system (iOS or Android), offering maximum performance. Hybrid lets you use the same code for both, reducing cost and development time, with near-native performance today.

It depends on complexity. A simple MVP can take 2 to 3 months. Complex apps with backend, admin panel and integrations can take 4 to 6 months or more.

Yes, we handle the whole submission process, metadata, screenshots and compliance with App Store and Google Play guidelines.

Absolutely. All developed code is client property and delivered at the end of the project via a Git repository.

By the problem, not by fashion. Rule of thumb: critical performance, sensors and heavy hardware lean native (Swift/Kotlin); balanced timelines and budget with quality lean Flutter or React Native. The decision is yours, with our technical recommendation documented.

As you prefer: sustainment with SLA (evolution, OS and store updates, monitoring) or an assisted handover to your team, with complete documentation.
