An app that should be a website
If people use it once a year, a fast mobile website is cheaper and easier to find. We say so.

Mobile app development company for businesses in the USA and Canada
PromotEdge International works as a mobile app development company for businesses in the USA, Canada and other markets. We plan, design, build and launch iOS and Android apps, with the back end they need, and publish them in your own App Store and Google Play accounts. Our delivery team is in India.
An app your customers or staff actually use, published under your name in both stores.
In short
An app earns its place on a phone when it does a job better than a website can: offline use, notifications, the camera or location. We start by checking that your idea needs an app at all, then build the smallest version worth releasing.
Once your app is live, see our app store optimization services page.

Common challenges
Why apps fail, and what we do about it
Typical situations, not results from a named client.
Too many features in version one
Big first releases ship late. We launch the core job first and add from real use.
Rejected by the store
Apps that break store rules are sent back. We check the guidelines before submission.
No plan after launch
Phones and operating systems update every year, so apps need regular care.
How we work
How an app project runs
- 01
Discovery
We test the idea against the job it must do, and agree the first version.
- 02
Design and prototype
Clickable screens, tried by your team or real users before code.
- 03
Build in steps
Regular test builds you install on your own phone.
- 04
Beta and store submission
A beta for your team, then submission from your developer accounts.
- 05
Launch and improve
We watch crash reports and reviews, and plan the next release.
What a mobile app development company does
A mobile app development company turns an idea into an app people install: the plan, the design, the app itself, the server behind it, and the launch in the stores.
Both stores check apps before they go live. Apple reviews every app and update against its App Store Review Guidelines, and Google Play applies its Developer Program Policies. Each store also charges the app owner a developer account fee. We publish from your accounts, so the app and its reviews stay yours.

Cost
What mobile app development costs
There is no public price list, because the cost follows the job.
What affects the cost
- iOS, Android or both
- How many screens and features
- What the back end must do
- Support needs after launch
How we price
Store fees, hosting and third-party services are separate and paid by you. You see the scope and the fee in writing before work starts.
Questions buyers ask us
It plans, designs, builds, tests and launches apps for iOS and Android, including the server and admin panel behind them, and supports them after launch.
An app makes sense when people use it often, or it needs offline use, notifications, the camera or location. If not, a fast mobile website is usually cheaper and easier for people to find.
You should.
It varies by store and by app. We submit with time to spare before any launch date, and fix anything a reviewer flags.
Yes. Reviews run on video calls in your working hours, and you install test builds on your own phone. We travel to our clients every 3 to 4 months, and we are available round the clock, 24x7, as per your location.

A real person reads every message and replies.
Guides on this topic
- Costs
App maintenance cost: what you pay after launch
An app is not finished at launch. Phones update, Apple and Google raise their rules every year, libraries go out of date, and users find bugs the tests missed. An app that is not maintained eventually stops installing on new phones or drops out of the store. This guide sets out what maintenance covers, the fixed fees and yearly platform requirements from Apple's and Google's own pages, and a way to budget the work from public rates. It is part of our guide to app development cost. We publish no rate card of our own.
- Comparisons
Flutter vs React Native in 2026
If an app needs to run on both iPhone and Android, the first technical decision is usually whether to write it once in a cross-platform framework, and if so which. Flutter and React Native are the two most common choices, and they take different routes to the same goal. This guide compares them on their own documentation: the language, how each draws the screen, the platforms they reach, and what that means for design, team, performance and upkeep. It is part of our guide to app development cost.
- Costs
Healthcare app development cost: what drives the price
Healthcare app development cost is asked as one question and answered badly as one number. The honest answer is a method: the hours the app takes multiplied by what those hours cost, plus the hours the rules add, plus the small fees and the large recurring costs after launch. This guide gives the method with public wage data, names the rules that add work, and shows where the money goes. It does not quote our prices, because scope decides them, and it does not cite a vendor price survey, because we did not open one as a primary source. It sits under our main guide to healthcare digital marketing. It is general information, not legal advice.
- Guides
How long does it take to build an app?
"How long will the app take?" is usually the second question after "how much?", and the two are linked: time is most of the cost. The answer depends less on the technology than on how much the first version tries to do, how many platforms and systems it touches, and how quickly decisions get made. This guide gives phase-by-phase timelines from public sources, explains what stretches or shortens a build, and shows how an MVP gets a first version out sooner. It is part of our guide to app development cost.
