Voice
Natural voice input and conversational experiences where typing is not the best interface.
Mobile app development
Mobile app development, built to ship and built to last.
We design and build iOS and Android apps — native and cross-platform — that feel right on the device and hold up in the store. From first version to a product people keep on their home screen.
On mobile, the details are the product.
A mobile app lives in someone's pocket, judged in seconds, and rated in public. That makes the details — motion, responsiveness, battery, the feel of a gesture — not polish but product. Getting them right is the difference between an app people keep and one they delete.
We build native and cross-platform mobile apps with that craft built in, and with the engineering discipline that keeps them stable across devices and OS versions.
What we build.
Native iOS & Android apps
Platform-true experiences that feel right on each device.
Cross-platform apps
One codebase across iOS and Android when it's the right call.
Consumer products
Apps built to earn a place on the home screen and keep it.
Sensor & background apps
Location, motion, and background work done reliably and efficiently.
Enterprise & field apps
Mobile software your workforce actually depends on.
App rescues & rebuilds
Stabilize and relaunch an app a previous team couldn't ship.
Intelligence that travels with the user.
Mobile devices carry context that traditional software rarely has: camera, voice, movement, sensors, local data, and the environment around the user.
Used carefully, AI can turn that context into a more useful product without compromising the craft, performance, privacy, and reliability a mobile app still has to get right.
Camera & documents
Understand images, capture documents, and turn visual input into structured product workflows.
Sensors & context
Combine device signals with product logic to make experiences more relevant to what is happening now.
On-device + cloud
Choose local or cloud inference based on latency, capability, privacy, connectivity, and cost.
Offline intelligence
Keep important experiences useful when connectivity is poor or unavailable.
Contextual action
Use AI to recommend or initiate the right next step, while keeping permissions and consequential actions under control.
AI belongs on mobile when it makes real use of context — not because the product needs an AI feature.
A mobile app is a channel to your customer.
Done well, it's a direct line to revenue, engagement, and loyalty. We build for the outcome, not just the feature list.
Open a new revenue channel
Turn mobile into a meaningful share of how customers buy and engage.
Earn a place on the home screen
Craft and reliability that keep users coming back instead of churning.
Reach users where they are
Meet customers on the device they use most, done right for it.
Rescue a stalled app
Relaunch a product a previous team couldn't get across the line.
Fast doesn't have to mean unpredictable.
The reason software runs late and over budget is rarely the code — it's the chaos around it. We plan before we build, run the work as Missions you can watch, validate every change against an explicit definition of done, and review it before it ships. You get the speed of AI with the discipline that keeps software maintainable for years.
Proven on software companies actually depend on.
14 years building production software for
Proof — Yatra
16%
of revenue from mobile, up from ~0.5%
We redesigned Yatra's app and mobile jumped from around 0.5% to over 16% of overall revenue in two months.
Yatra, one of India's largest travel brands, needed its mobile experience to carry real commercial weight. We redesigned the app, and within two months of launch mobile soared from roughly 0.5% to more than 16% of overall revenue, with App Store ratings climbing alongside it.
A 14-year playbook, enforced by software.
Across more than 200 products, the difference between projects that ship clean and projects that spiral came down to a few disciplines. We turned them into how Cortex runs every build — so they happen every time, not just when someone remembers.
Plan in Missions
Every build starts as a plan a human approves — scope, definition of done, and boundaries — before a line of code is written.
Trace every commit
Each change is tied back to the plan it came from, so you can always see what was built, why, and by whom.
Test the contract
Work is validated against an explicit definition of done, not a demo — proven correct before it ever ships.
From COBOL to serverless.
We build on a modern stack and we read the old one before we replace it. Over a decade across enterprises means we're as comfortable in a legacy monolith as we are on the edge.
Modern stack
- React & TypeScript
- Node.js, Python & Go
- Serverless & edge
- Cloud-native (AWS / GCP / Azure)
- Postgres & modern data stores
- AI / LLM application layers
Legacy we speak
- COBOL & mainframe logic
- Java & .NET monoliths
- Legacy relational databases
- On-prem & regulated environments
- Undocumented internal APIs
- Systems no one wants to touch
Who it's for.
Companies where mobile is the product
When the app is the business, craft and reliability are non-negotiable.
Brands growing a mobile channel
Turn mobile from a rounding error into a meaningful share of revenue.
Teams with a stalled app
Relaunch a product that a previous team couldn't ship or stabilize.
Not a typical software company.
Forward-deployed engineers, not juniors
Every engagement is led by engineers who've shipped production software for years.
AI speed, with the controls
Validation and human review are built into the process, not bolted on at the end.
Fully yours, fully accountable
Full IP assignment, an NDA from the first conversation, and an audit trail that outlives the project.
Questions, answered.
Should we build native or cross-platform?
It depends on your product. Native gives the tightest platform feel and access to every device capability; cross-platform can be faster and cheaper to maintain when the experience allows it. We make the call with you based on your users and roadmap, not a default preference.
Can you build for both iOS and Android?
Yes. We build native iOS, native Android, and cross-platform apps, and we've shipped consumer and enterprise apps across both stores.
Can you take over an app another team started?
Yes. We regularly stabilize, finish, and relaunch apps a previous team couldn't ship, keeping what works and fixing what doesn't.
Who owns the mobile app you build?
You do, completely. Every engagement includes full IP assignment and is covered by an NDA from the first conversation.
