QA Testing Services for SaaS Startups: How Vervali Works
How Vervali tests a SaaS startup's product: what to test first, when to outsource, manual or automation, the monthly cost at published rates, and how the free pilot…
Cross-Platform App Development
in Flutter and React Native
One Flutter or React Native codebase for iOS and Android, tested on real devices by the same team, with store submission in the quote, 9am to 1pm Eastern, with delivery from India. We ship both stores from that codebase, and name any module that still has to stay native. The stack, the device list and the quote are agreed before the build starts.

One Codebase, Two Stores
Flutter or React Native, tested on real phones, with both store listings in the quote.
Flutter
One Dart codebase for iOS and Android when Flutter is the fit. The quote names the first release and any module that stays native.
React Native
One JavaScript codebase when React Native is the stack you already run, or the stack the quote names. Not every native module ports cleanly.
Real Devices and Stores
The same team tests on phones, then handles App Store and Google Play submission. Wider device coverage uses mobile application testing.
Both stores from one codebase, tested on real phones before you submit.
Book a CallWhat the First Release Includes
The stack, the integrations and the weeks are written down before anyone writes code.
Stack Choice
Flutter, React Native, or a native module where the camera or sensors are the product. Native Swift and Kotlin run through mobile app development.
Integrations
Payments, CRM and notifications are named in the quote, so none of them arrive as a surprise in week ten.
Weeks
A first release is typically 8 to 12 weeks. A feature-rich app is 14 to 20 weeks or more, in increments you can test.
After the Stores Review It
A rejected build is a fix, and the weeks after launch are named if you want them.
Store Fixes
We do not promise an App Store or Play approval. Guidelines change, and a rejection is fixed and resubmitted.
Maintenance
OS updates and defects after launch, 9am to 1pm Eastern with delivery from India. Longer version work uses software maintenance and version upgrades.
Watches and Headsets
A watch that is the product uses wearable app development. A headset uses AR and VR app development.
Case Studies
Mobile products that had to work on real devices and reach both stores.
Financial services · Customer engagement platform
Motilal Oswal Financial Services needed a platform that lifted customer engagement. Vervali owned the interface and every technical integration, and delivered on time and within budget. After launch, more than 2,000 users were actively using it.
2,000+ active users post-launchOn time and within budgetEnterprise Mobile Enhancements
Tech-Excel Computer Services needed geofencing and fast bug fixes. The app launched on the Play Store and the App Store.
Private-Sector Banks
Two leading private-sector banks gained 60% faster loan processing and 50% less agent onboarding time on platforms tested before each release.
How a Cross-Platform Build Starts
A first release typically takes 8 to 12 weeks, 9am to 1pm Eastern with delivery from India.

Listing work named in the quote is submitted, and a rejection is fixed and sent again.
Frequently Asked Questions
Cross-platform app development is one codebase that ships to iOS and Android. Here that is Flutter or React Native, tested on real devices by the same team, with store submission in the quote. Native Swift and Kotlin are built through mobile app development when the operating system surface is the product. We help you choose. The work runs 9am to 1pm Eastern, with delivery from India.
One team ships both stores from a single codebase, so a first release is typically faster than two native apps. Native still wins when the camera, sensors or the smoothest interface is the product. Not every module ports cleanly, and the quote names what stays native. A free scoping session is how we see whether Flutter, React Native or native is the fit. Testing on real devices is part of the same engagement.
A first release is typically 8 to 12 weeks. A feature-rich app is 14 to 20 weeks or more. What moves the timeline is integrations, store submission, and whether native modules still belong in the mix. The written quote follows a free scoping session, once the first release is written down. Delivery is from India, 9am to 1pm Eastern. We do not publish a project total before we have seen the product.
Yes, when rewriting is cheaper than maintaining two native codebases. Not every native module ports cleanly. A free scoping session shows what has to stay native and what can move. Store submission is in the quote for the rewritten app. Native-only work stays with mobile app development. The quote names the weeks after we see the current apps. We do not promise a rewrite in a weekend.
Store submission is in the quote. We test on real devices and handle the listing work that quote names. We do not promise an App Store or Play approval, because the stores control that decision and the guidelines change. A rejected build is fixed and resubmitted. The scoping session looks at what each store is likely to ask before the first binary is ready.
Yes, when those APIs are named in the quote: payments, CRM, notifications and the other services you listed. We do not invent a connector catalogue. The scoping session decides which integrations belong in the first release and which wait. A storefront that also needs an app can include ecommerce work in the same quote. Interface design is scoped with the screens, so the build is not waiting on a separate design pass.
Yes, as a separate line when you want it. After launch we handle store fixes, OS updates and the defects the first release surfaces. Longer version work runs through software maintenance and version upgrades. Coverage is 9am to 1pm Eastern, with delivery from India. The quote names the maintenance window if you want it with the first release. A free scoping session shows what that window should cover.
Work is scoped to the stack, the integrations and the weeks, then quoted before we start. Clutch lists Vervali at $25 to $49 per hour. A first release is typically 8 to 12 weeks. A feature-rich app is 14 to 20 weeks or more. Store submission is included when the quote says so. After a free scoping session, the written quote names the weeks and the price. You are not required to buy maintenance in the same engagement.
