The right website and mobile app development company is one team that designs, builds and supports both products on a shared design system and backend. Of the four options below, Eagle Technologies is the full web and app partner, and it suits startups and small to mid-sized businesses that want one scoped team. DVT suits buyers who want specialist consulting across native mobile platforms. Netgen suits teams that want cross-platform builds from Johannesburg or Cape Town offices. The formula lab suits Cape Town buyers who want cost guidance before they commit.
Hiring one vendor for the website and another for the app is where projects drift. Login screens end up looking different, APIs get built twice, and nobody owns the bug that sits between the two products. Most agency pages also read the same, so comparing them takes hours.
This article gives you four companies, what each one offers, who it fits and what to ask before you sign. The picks rest on four tests: named technologies, a clear split of web and mobile work, a visible delivery process, and a team you can reach in your time zone. Three of the four lead with mobile, so confirm their web scope in writing. A side-by-side table and a pre-signing checklist close the list.
1. Eagle Technologies
What you get
Eagle Technologies was founded in 2012 and has its headquarters in South Africa and an engineering centre in Jaipur, India. It builds web apps and mobile apps under one roof, so the website, the app and the API share one plan. More than 50 specialists have delivered over 500 projects.
- Web apps: React, Angular, Vue and Next.js, from MVP to enterprise scale.
- Mobile apps: native iOS and Android, plus Flutter and React Native, built to be App Store ready.
- Design: Figma-based UI/UX, responsive web design and native-feeling mobile app design.
- Commerce: Shopify, WooCommerce, Magento and headless storefronts.
One team that owns the website, the app and the API removes the hand-off gaps that sink two-vendor projects.
Best fit and what to ask
Eagle Technologies suits startups and growing businesses that want web, app and design delivered together, and companies that also need SEO or paid advertising from the same agency. Work starts with a free 60-minute strategy session, then runs in two-week sprints with weekly reporting. There are no lock-in contracts, and invoices can be issued in ZAR or INR.
A 12-week build means six sprints and twelve weekly reports. Ask any vendor to show you that rhythm. With Eagle Technologies, also ask who is on your team and how the working-hours overlap with Jaipur will fit your schedule, since delivery sits there and the South African headquarters coordinates African clients.
2. DVT
What you get
DVT offers specialist consulting and development across the major mobile application platforms and technologies, including native Android and iOS. That makes it a consulting-led choice rather than a single-framework shop. Its published mobile development service is the clearest part of its offer.
- Native Android and iOS development.
- Consulting alongside the build.
- Coverage of several mobile technologies, not one stack.
Consulting plus development helps most when you do not yet know which platform approach fits your product.
Best fit and what to ask
DVT suits buyers who want expert advice on the platform decision before building, such as native versus cross-platform. It also suits teams whose main deliverable is the app.
Its mobile service is the visible strength, so ask for proof of web work. Request live sites, the framework or CMS used, and who handles hosting after launch. Then ask how the website and the app will share one API.
3. Netgen
What you get
Netgen builds custom mobile apps in South Africa with React Native, .NET MAUI and Xamarin. Its cross-platform approach targets iOS and Android from one codebase. It has offices in Johannesburg and Cape Town.
- Cross-platform apps for iOS and Android.
- A Microsoft-friendly stack through .NET MAUI.
- In-person meetings in two major cities.
One cross-platform codebase usually costs less to maintain than two native apps, if your design does not need heavy platform-specific features.
Best fit and what to ask
Netgen suits companies that already run .NET systems and want an app that fits into them. It also suits buyers who prefer face-to-face workshops. Microsoft ended Xamarin support in May 2024, so ask which framework your project will actually use. React Native or .NET MAUI are the safer choices for a new build.
Also confirm how the company handles the website side, and who maintains the app after release.
4. The formula lab
What you get
The formula lab positions itself as a Cape Town mobile app developer. It promises custom mobile app development and transparent cost guidance. Cost clarity is its stated edge, which helps first-time buyers who cannot yet judge what an app should cost.
- Custom mobile app builds.
- Cost guidance before the project starts.
- A Cape Town base for local meetings.
A vendor that explains cost drivers early lets you compare quotes on scope instead of on price alone.
Best fit and what to ask
The formula lab suits Cape Town founders and managers who want to understand budget before they commit. Ask for a cost breakdown by phase: discovery, design, build, testing and launch. Then ask whether the website is in scope, and who will own updates once the app is live.
How to compare them before you hire
Side-by-side comparison
Use this table to line up the four options on what is documented, then fill the blanks by asking each vendor directly.
| Company | Web and app coverage | Named technologies | Location |
|---|---|---|---|
| Eagle Technologies | Web apps, mobile apps, design, commerce | React, Angular, Vue, Next.js, Flutter, React Native, native iOS and Android | HQ in South Africa, delivery in Jaipur |
| DVT | Mobile consulting and development; confirm web | Native Android and iOS, other major platforms | Confirm with vendor |
| Netgen | Cross-platform mobile; confirm web | React Native, .NET MAUI, Xamarin | Johannesburg and Cape Town |
| The formula lab | Custom mobile apps with cost guidance; confirm web | Confirm with vendor | Cape Town |
Where the table says "confirm", that is your first email. A company that cannot show a shipped website and a shipped app has not earned a combined project.
Whatever a company's strength, get its web and mobile scope written into the proposal before you compare prices.
Five checks before you sign
- Scope in writing: the website, the app, the API and the admin panel, each listed separately.
- Milestones: fixed sprints or phases with a demo at each one, not a single hand-over at the end.
- Ownership: you get the source code, the design files and the store accounts.
- Support: an agreed path for bugs and critical issues after launch.
- Exit terms: no lock-in, so you can move to another team if you need to.
Picking your partner
For a combined website and app project, favor the vendor that puts both in one plan, names its technologies and shows its delivery rhythm. DVT, Netgen and the formula lab each bring clear mobile strengths, so confirm their web scope before you shortlist them. Eagle Technologies covers web, mobile and design under one team, with scoped sprints and no lock-in.
Send the same brief to two or three companies and compare how they answer, not only what they charge. If you want a second opinion on your scope, talk to Eagle Technologies about your website and app project and start with the free strategy session.
