Why CSlant

Faster, With Less Risk

The features every app needs are already built and well tested, so time and budget go into what makes yours different.

Proven Features

Auth & OTP, payments, notifications, chat, booking… already built and well tested — shorter timelines, fewer surprises.

AI Inside Your Workflows

AI assistants, smart search and document scanning wired into your workflows, not bolted on from outside.

You Own The Code

Once paid in full, the complete source code and deployment docs are yours.

One Team, End To End

Backend, app, infrastructure and operations handled by the same team — no finger-pointing between vendors.

Choosing The Right Tech

Native, Cross-Platform, Or System-Integrated?

We help you pick the right technical direction based on budget, timeline, and long-term goals.

Top Performance

Native (Separate iOS/Android)

The best possible performance, with full access to device capabilities — ideal for demanding apps.

  • Full access to camera, sensors, push notifications, and platform-specific APIs.
  • The smoothest, most responsive experience since each platform is optimized on its own.
  • A good fit for games, graphics-heavy apps, or anything that needs deep hardware access.
Fits Best When

Games, finance apps, or anything that needs deep hardware access.

Lower Cost

Cross-Platform (React Native/Flutter)

One codebase for both iOS and Android, cutting development time and cost without sacrificing a smooth experience.

  • One team, one codebase — meaningful savings on both build time and long-term maintenance.
  • Faster time to market, ideal for products that need to validate demand early.
  • Still delivers a near-native look and feel for the vast majority of use cases.
Fits Best When

Most commercial and management apps, and MVPs that need to launch fast.

Seamless Connection

Integration With Existing Systems

Connect directly to your existing backend, ERP, or CRM system — whatever platform or language it's built on.

  • Two-way sync over an API with the internal management systems you already run on.
  • No need to rebuild business logic from scratch — reuse the workflows and data you already have.
  • A good fit for businesses adding a mobile channel to a system already in production.
Fits Best When

Businesses already running a management system that want to add a mobile channel.

Smarter Apps

AI Built Into Your Mobile App

We weave AI (Gemini) and document recognition (OCR) straight into the app's core experience — not bolted on as an afterthought.

Document Scan & OCR

Snap a photo of an invoice or receipt — the app extracts vendor, amount, and date and saves it straight to the backend.

AI Assistant (Gemini)

Ask natural-language questions about operational data or revenue, right from the mobile app.

Workflow Automation

Cut down manual steps inside the app with automated flows synced with your backend.

System Analytics

Check key numbers from your existing backend on the go, no need to open the web dashboard.

Product-grade Quality

What A Modern App Should Have

The standards CSlant applies to every app — from user experience to the infrastructure behind it.

Platform-native UI/UX

Follows iOS and Android design guidelines, familiar from the first tap.

Auto-scaling

Infrastructure scales with traffic, so growth never takes you down.

Stability & Monitoring

Continuous error tracking and alerting keep the app available.

Layered Security

Encryption, API authentication and strict permissions at every layer.

Sync & Offline

Real-time data sync, still usable without a connection.

Hardware Access

Camera, GPS, biometrics, NFC — used where it matters, battery-friendly.

Timely Notifications

Segmented push notifications that bring users back.

Measurement & Analytics

Behaviour and funnel tracking for data-driven decisions.

How We Work

From Idea To A Complete App

A clear, transparent process at every stage.

DEPLOYED PROGRESS
  1. Step 01

    Define Scope

    Clarify goals, core features, target users, and the integration points with your existing backend before design starts.

  2. Step 02

    Design & Early Testing

    Build a prototype to validate the experience before full development.

  3. Step 03

    Build & Regular Updates

    Development happens in stages, with frequent progress updates so you always know where things stand.

  4. Step 04

    Launch & Handover

    Publish to the App Store/Google Play and hand over the full source code and documentation.

You keep full ownership of the source code — handed over in full once the project wraps.

Before You Start A Project

Frequently Asked Questions About App Development

A few things clients often ask before starting a mobile app project.

The CSlant Team

The CSlant Team

Discuss Your Project
Q1 Should I choose a Native app or cross-platform (React Native/Flutter)?

It depends on your budget and performance needs. Apps that need top performance and deep hardware access usually fit Native; most regular commercial apps do well with cross-platform, saving cost and time.

Q2 Do I own the full app source code once it is finished?

Yes. Once final payment is complete, you receive the full source code and deployment documentation for the app.

Q3 Does CSlant help publish the app to the App Store and Google Play?

Yes, we handle the full submission process and make sure it complies with each platform's policies.

Q4 Can the app integrate with our company's existing backend, ERP, or CRM system?

Yes. We have experience connecting mobile apps to existing backend, ERP, or CRM systems via APIs — whatever platform or language they're built on, including systems CSlant itself built.

Q5 Is the app supported after launch?

Yes, all our packages include post-launch support; you can also subscribe to a longer-term maintenance plan if you need ongoing technical support.

Q6 How long does it take to build an app?

Typically 6–10 weeks for Starter and 3–5 months for Growth, depending on scope. We agree a concrete roadmap with you before starting.

Q7 Can we start with an MVP and grow it later?

Yes. We recommend an MVP to validate the market first; the architecture is designed to grow in phases without a rewrite.

Q8 How is AI built into the app?

It depends on the problem: a Q&A assistant over your data, smart search, personalised recommendations or document scanning (OCR). CSlant advises which parts add real value before building them.

Q9 How much does an app cost?

It depends on the number of screens, features, integrations and platforms. The plans above give a reference range; a detailed quote follows the requirements call.

Q10 What do I need to prepare before building an app?

Your goals, main user groups, a wish list of features and a few reference apps. If things are still fuzzy, we start with a discovery session and a screen-flow design.

Q11 Does the app need a backend and an admin panel?

Almost always: the backend stores data and runs business logic, and the admin panel manages users, content and orders. CSlant builds all three.

Q12 Whose name are the App Store and Google Play accounts in?

They should be in your company's name. CSlant guides the sign-up and handles the review process; account fees are paid directly to Apple and Google.

Q13 Can the app work offline?

Depending on the feature, the app can store data on the device and sync when back online — handy for sales, stock-taking or field-survey apps.

Q14 How is user data kept secure in the app?

Encrypted connections, token-based authentication, role-based permissions, secure on-device storage for sensitive data, and compliance with App Store and Google Play privacy requirements.

Q15 Can you take over an app built by another team?

Yes. We review the existing code first, then propose gradual upgrades or rebuild only what is needed, without disrupting your users.

Q16 Can the app include payments, push notifications and maps?

Yes: payment gateways, push notifications, maps and location, social login and other common third-party services.
