Purrweb builds custom mobile apps for startups and growing businesses. We design mobile applications for Android and iOS around your workflows, integrations, and user journeys instead of forcing an idea into a template. Our development team covers product discovery, UI/UX design, engineering, quality assurance, store release, and post-launch support. Since 2014, we have helped clients move from an early product scope to a working custom app with the documentation needed for the next release or an internal handover.

| Criteria | Custom development | App builder or template |
| Ownership | Product-specific code and architecture | Depends on the platform |
| Integrations | Custom APIs and data flows | Available connectors only |
| User experience | Built for specific users and tasks | Standard layouts and interactions |
| Scalability | Planned around expected growth | Limited by platform capabilities |
| Security | Set around the data and access model | Uses shared platform controls |
| Launch speed | Longer discovery and engineering | Faster for standard workflows |
| Initial cost | Higher upfront investment | Lower for a basic version |
| Criteria | Native | Cross-platform |
| Codebase | Separate code for iOS and Android | Most code is shared |
| Best fit | Deep OS or hardware integration | Similar workflows on both platforms |
| Time to market | Each platform requires its own implementation | One team develops both releases |
| Initial budget | Higher when both platforms launch together | Lower when the core scope is shared |
| Platform APIs | Direct access to native capabilities | Native modules cover platform-specific features |
| Maintenance | Changes are implemented in each codebase | Most product changes are implemented once |
MVP / new product
~30% saved with React Native vs two native teams
Plus UI/UX design $5k–$5k · QA & project management included
What drives your estimate: iOS + Android build (+15%)
To fit a smaller budget: start with one platform
From $30,000

I'm the CTO of Personalised Co., an app for tracking supplement and vitamin intake. Purrweb designed the product's UI/UX with a Shopify store integration for automatic reordering, and built an interface for healthy living with personalized tracking.
Personalised Co. is an app for people who take supplements and vitamins regularly: intake tracking and automatic reordering through a Shopify integration. Purrweb designed the product's UI/UX with a supplement marketplace and a personal intake schedule.

I'm the CEO of KEM, a P2P mobile payment service for the Kuwaiti market, where not everyone has access to online banking. Our banking partners needed an MVP for demonstrations. Purrweb delivered the design and the MVP, working around the restrictions on connecting to the banking API. On completion, they handed the project over to our in-house team with full documentation and a month of technical support.
KEM is a P2P app for instant money transfers in the Kuwaiti market: linked bank cards, money requests from the contact list, and transaction history. The key challenge: for security reasons, Kuwaiti banks don't allow outside developers to work with their API — so Purrweb built the back end on mock data, fully simulating the final functionality for demos.

I'm building Buzz, an app for finding and organizing events in small American towns. I came to Purrweb with almost nothing — just an idea. Purrweb helped with marketing, brand identity, and the logo, and walked the whole road to MVP with us, even when our requirements shifted a lot in the early stages. I valued the flexibility and the quality of the design.
Buzz is a geosocial service for residents of small American towns: a geolocation-based feed of public events, private events with friend invites, group chats, and a Ticketmaster integration. Purrweb created the brand identity from scratch, optimized the architecture, reused ready-made modules, and shipped the MVP in 12 months.

Cases show products with similar platforms, integrations, user roles, or regulatory constraints.
The team asks about workflows, data, dependencies, success criteria, and scope boundaries before estimating.
The proposed team includes the design, mobile, backend, QA, and release roles the project requires.
Review cadence, decision owners, reporting format, and escalation paths are defined before delivery starts.
The contract explains intellectual-property assignment, source-code transfer, documentation, accounts, and access ownership.
Testing responsibilities, supported devices, acceptance criteria, and app-store submission are part of the plan.
Post-launch responsibilities, security controls, and required compliance work are scoped rather than implied.
| Product scenario | Planning reference | Main timeline drivers |
| Focused MVP with one primary workflow | About 5 months | Discovery, prototype, core back end, one shared release scope, and store submission |
| Multi-role product or marketplace | About 8 months | Several user journeys, payments, admin tools, real-time states, and external APIs |
| Fintech, IoT, or integration-heavy product | 9+ months | Security controls, hardware or banking dependencies, migration, and extended testing |
