Why the best custom application development agency delivers faster
Our process is built for speed without sacrificing quality.
IRPR has shipped over 200 custom applications across 50 countries. Our team of senior engineers averages 7+ years of experience each.
We use a structured 4-phase approach: Idea, Roadmap, Product, Release. This eliminates delays and ensures 98% on-time delivery.
Custom development shop vs IRPR
Most agencies promise quality but deliver delays. We fix that.
Generic dev shops often start with unclear requirements and bill hourly. Scope creep and junior developers lead to missed deadlines.
IRPR uses a fixed-price Roadmap phase to lock scope, assigns senior engineers, and delivers in 8-12 weeks with full code ownership.

- No fixed timeline
- Junior devs assigned
- No post-launch support
- Roadmap phase nails scope
