What's included

The problem with apps nobody keeps

Many apps are a website squeezed into a phone. They are slow, confusing on first open and deleted within the week.

We design around the few things your users actually need to do, build for iOS and Android, test on real devices and handle the store submissions.

Our standard
  • Designed around key user tasks
  • Tested on real devices
  • App store submission handled
  • Updates and support after launch

How we work

A process built for results

Clear milestones, regular updates and no surprises. Here’s how we get from idea to launch.

  1. Step 01

    Discovery & Goals

    We ask the right questions to understand how your business works today, what is slowing it down and what success should look like.

    • Goals & success metrics
    • Audit of current setup

    Timeline3–5 days

  2. Step 02

    Plan & Design

    We agree scope, timeline and approach, then map the flows or design the screens so you see what you are getting before we build.

    • Fixed scope & timeline
    • Flows or screen designs

    Timeline1–2 weeks

  3. Step 03

    Build & Test

    We build in stages and keep you updated. Everything is tested on real devices and in real conditions before it goes live.

    • Weekly progress demos
    • Real-device testing

    Timeline2–6 weeks

  4. Step 04

    Launch & Improve

    We handle the launch, watch how it performs, fix what needs fixing and keep improving based on the data.

    • Go-live & handover
    • Monthly performance reviews

    Timeline1 week + ongoing

What clients say

Kshitij Shah

Co-founder, MyFinMate
“Our users had to dig through screens to answer simple questions about their money. Hexagon added an AI assistant that answers from their own data, and nothing changes without the user's approval. It solved a real problem for our users and saved us months of in-house development. We highly recommend Hexagon for serious AI work.”

Kshitij Shah

Co-founder, MyFinMate
“Hexagon integrated an AI assistant into our app smoothly, without disrupting anything our users relied on. They were clear and honest about what the assistant could do. It saved us the time and cost of building an AI team in-house. We highly recommend Hexagon for app and AI work.”

Archana

Team Head, Pranic Healing Sounds
“Our old app kept crashing and customers were unhappy. Hexagon rebuilt it to be fast, stable and easy to use. Complaints have dropped sharply, and our support team has far less to deal with. They solved a problem that was hurting our business. We highly recommend Hexagon.”

Vijay C Doshi

Founder, Vincitore Wellness Estate
“Hexagon helped us decide what to leave out of our first version, which saved us a lot of money. The app launched on schedule, and they stayed with us after launch for fixes and improvements. Their guidance was as valuable as their development. Highly recommended.”

Helmut Honermann

Managing Director, PureLife NOVA-c
“Hexagon built our app for both Android and iOS and handled the store launch for us. Regular demos kept us involved, so there were no surprises. Using one team for everything saved us time and coordination costs. A professional team we highly recommend.”

FAQ

Common questions

Everything you need to know before we start working together.

Native or cross-platform: which should we build?

Cross-platform frameworks such as Flutter or React Native give you iOS and Android from one codebase, which suits most business apps. Native development makes sense when the app depends heavily on device features or performance. We recommend one after discovery.

Do you publish the app to the App Store and Google Play?

Yes. We prepare the store listings and submit the app for review. The listing stays in your developer account, so you own it.

Can you add AI features to an existing app?

Yes. For the MyFinMate personal finance app we added an AI agent beside the existing app: users ask questions about their own data in chat, and any change it proposes runs only after they approve it.

Is the backend included?

Yes. The backend, admin panel and integrations with your other systems are built by the same team as the app.
