A SaaS app — mobile or web — lives or dies on activation rate. The sign-up is cheap; the first-session 'aha moment' is what decides whether a user becomes a paying customer. Building a SaaS app means optimising that first 5 minutes (onboarding, first feature use, first value moment), then layering depth for power users. We build mobile in React Native (shared iOS/Android) with native modules where biometric or platform-specific features demand it, and web apps in Next.js or Remix with modern state management (Zustand, Jotai, or React Query depending on data shape).

Common Questions
Everything you need to know about App Development for SaaS & B2B Tech brands
React Native or native for SaaS mobile?
React Native for 80% of SaaS where UI is form-heavy and data-driven. Native (Swift/Kotlin) where you need deep platform integration — advanced biometrics, document scanning, platform-specific APIs. Most Indian SaaS products we build are React Native.
Razorpay, Stripe or Paddle?
Razorpay for India-only SaaS with INR pricing. Stripe for global with multi-currency, sophisticated billing logic, and US/EU customer base. Paddle for global with simpler billing needs and Merchant-of-Record advantages (handles tax globally). We'll help decide based on your customer geography and billing complexity.
Do you handle App Store IAP for subscriptions?
Yes. Apple's 30% cut is real — we implement both IAP (where required by ASRG 3.1.1) and external-billing patterns with appropriate compliance. For B2B SaaS where buyer is paying on company card not personal Apple ID, external billing with web sign-up is usually the right call.
Can you rebuild our existing SaaS app?
Yes. Typical rebuilds: modernise React Native version, refactor state management (often from Redux to Zustand or React Query), rebuild onboarding funnel for activation, integrate feature flags. Rebuild projects run 16–24 weeks with parallel maintenance on the current app.
