Store releases and support
Store releases, phased rollouts, and the version support that follows launch.
Mobile App Development
What is mobile app development?
Mobile app development means building software that installs on a phone and runs against that device's capabilities — camera, biometrics, notifications, and storage that persists whether or not there's a connection. The engineering that separates a good app from a demo is what happens when things go wrong: no signal, a denied permission, a backgrounded session.
React Native vs Flutter vs Native: How to Choose
Cross-platform gets you one codebase and most of the feel of native, which is the right trade for the majority of products. Choose native when the app depends on sustained frame rates, heavy device hardware, or a platform API that ships ahead of the bridges. We make that call in discovery and explain the reasoning.
Mobile App Development Cost
Discovery is fixed-price and produces a costed estimate. Two platforms cost more than one, offline support costs more than assuming connectivity, and anything touching payments or health data carries compliance work that shows up in the timeline.
Technology Stack for Mobile App Development
React Native and Flutter for cross-platform, Swift and Kotlin when native is the answer, with Node.js or Python behind the API. Chosen for what your team can hire for and maintain once the app is theirs.
How Long Mobile App Development Takes
A first release reaches the stores in ten to sixteen weeks, including review. Apple and Google review times are outside anyone's control, so we build them into the plan rather than discovering them in the final week. Release pipelines handle the builds so submission isn't a manual event.
Mobile app, web app, or SaaS — which do you need?
Mobile apps install on a device. Web applications run in a browser and need no download. SaaS platforms serve many customers from shared infrastructure. Most products need a mobile app and at least one of the other two.

Our Mobile App Development Process
How an idea becomes an app that passes review and behaves on real devices.
01
Discovery
Platform decisions, device targets, and offline behavior settled upfront.
02
Planning
Architecture and release strategy set, including store review lead times.
03
Design
Flows prototyped for each platform's conventions, then tested on devices.
04
Development
Two-week sprints with builds on your phone, not just on our screens.

Mobile App Development FAQs
Still have questions?
Talk to an engineerReact Native, Flutter, or fully native?
React Native or Flutter for most products — one codebase, close to native feel, and a smaller team to maintain. Native when the app depends on sustained frame rates, deep hardware access, or a platform API that hasn't been bridged yet.
How long does app store review take?
Apple typically reviews in a day or two, occasionally longer for a first submission or anything involving payments. Google is usually faster. We plan submission with buffer, because a rejection in the final week costs more than the delay itself.
Do you handle store submission and updates?
Yes. We submit under your developer accounts, keep your certificates and signing keys in your control, and handle version updates, phased rollouts, and store listing changes as part of ongoing support.d.
