Leading React Native App Development Company in Campinas

A tightly scoped project typically runs four to eight weeks; larger builds with custom integrations run three to five months. The variable that moves timelines most is not development speed - it is how quickly content, approvals and third-party access come back from your side. We publish a milestone schedule at kickoff so both sides can see slippage early.

Usually within one to two weeks, depending on current commitments. We would rather give you an honest start date than book you in immediately and then run a project slowly, which is the more common outcome when a supplier promises to start the same day.

No. Templates are cheap up front and expensive later, because the first genuinely custom requirement forces a rebuild. We design around your actual workflows and hand over clean, documented code you own outright.

Gletus Technology works across Campinas and the wider Brazil region. Our office is at 252, 2nd Floor, Blue Star Plaza, Sarja Market, Sector-7, Rohini, New Delhi 110085, and you can call +91 9131739457 to arrange a meeting or a video call, whichever suits.

Wherever possible those accounts are opened in your name and billed to you directly, so you retain control and can see exactly what infrastructure costs. We will recommend and configure the setup, but we do not sit in the middle of your hosting relationship.

Yes. We regularly take a defined workstream alongside an internal team - a module, a redesign or the search and performance work. Boundaries and code review conventions are agreed up front so nobody is working over the top of anyone else.

We can build offline-tolerant behaviour with local caching and background sync, which matters for field teams and for users in Campinas with patchy connectivity. It adds engineering effort, so we scope it explicitly rather than assuming it.

Yes. Depending on your budget and performance requirements we either build cross-platform from a single codebase or build native for each platform. We will explain the trade-off honestly - cross-platform halves maintenance cost, native wins where heavy graphics or deep hardware access are involved.

Yes, including store listing copy, screenshots, privacy declarations, review responses and the resubmission cycle if a build is rejected. Store policy rejections are routine on first submission and we plan for them rather than treating them as a crisis.

Yes - a significant share of our work is with early-stage and small businesses. Plenty of businesses in Campinas still have no properly optimised presence on Google, in Portuguese, which leaves qualified demand unclaimed. We scope a first phase that fits the budget available and expands once it is earning.

Usually yes, and often more so - a competitor already ranking proves the demand exists and is capturable. The market is shaped by the fact that it is PIX instant payments and installment checkout ("parcelamento") are commercial necessities, not extras. The route in is rarely a head-on fight; it is the specific queries they have neglected.

Brazil is PIX instant payments and installment checkout ("parcelamento") are commercial necessities, not extras. We factor that into the build rather than treating it as a future upgrade.

If you collect a name, an email or a payment from someone in Brazil, the data-protection law that applies in Brazil applies. In practice that means recorded consent rather than assumed consent, a stated retention period for each type of data, a working route for access and deletion requests, and a privacy notice that describes what actually happens. Locally it also means accounting for local language and currency conventions. We build and document to that standard; a formal compliance opinion should come from a qualified adviser in Brazil.

Yes - push delivery, crash and performance reporting, and an analytics pipeline, plus Firebase, AWS or Azure on the infrastructure side and Twilio or the WhatsApp Business API for messaging outside the app. Every connection is documented with its credentials, rate limits and failure behaviour, and the accounts are registered in your name so nothing goes dark if you change supplier.

We build to WCAG 2.2 AA: semantic headings, form controls with real labels, keyboard-operable navigation, a visible focus state, sufficient colour contrast, and no meaning carried by colour alone. It widens the audience you can sell to in Campinas, it is increasingly what procurement asks about, and it overlaps almost entirely with what search engines reward anyway.

You do, entirely - source code, database, design files, and every account we register on your behalf. Gateway, analytics and hosting accounts go in your name with you as owner and us added as a user, so if you stop working with us nothing needs re-registering and no service is interrupted. There is no fee to leave and no licence retained.

A focused MVP is typically 10 to 14 weeks; a multi-role product with payments and an admin panel runs 5 to 8 months. What moves those dates is rarely the engineering - it is how quickly content arrives, how many people must approve a decision, and whether a third-party system turns out to be documented. We commit to a date at the end of discovery, when it means something, rather than on the first call.
