# Software | ThatDeveloperGuy > Software and app development from ThatDeveloperGuy LLC: mobile apps for Android and iPhone, web applications, desktop apps and the systems behind them. - [Visible page](https://thatdeveloperguy.com/capabilities/software-development): The human readable and canonical version of this content. - [Site wide discovery index](https://thatdeveloperguy.com/llms.txt): The root index that joins every scoped discovery file. ## Overview Mobile apps, web applications and custom software, built and looked after by the same people. ## Page text Software covers the apps people carry, the applications they sign in to, and the systems that keep both running. Each part of the room links to the matching section below. Scope, exclusions and evidence for a specific engagement are written into the proposal for that engagement; this page describes the capability, not a contract. ## Page sections - [Mobile apps](https://thatdeveloperguy.com/capabilities/software-development#mobile-apps): Apps for Android and iPhone. The apps we have shipped install straight from the web to the home screen, with no store in between, and come with an Android package where a business wants one. Listing an app in the Apple App Store or Google Play is work we take on when a project calls for it. We help you choose based on what the app has to do. - [Web applications](https://thatdeveloperguy.com/capabilities/software-development#web-apps): Software people sign in to through a browser: member accounts, schedules, records, payments and the reports an owner needs to run the place. - [Desktop apps and custom software](https://thatdeveloperguy.com/capabilities/software-development#desktop-apps): The same application packaged for staff computers, for the jobs that are easier at a desk than on a phone. - [The systems behind the app](https://thatdeveloperguy.com/capabilities/software-development#systems): Sign in, databases, backups and monitoring. An app is only as dependable as what it runs on, so we build and operate that part too. - [Working with what you already use](https://thatdeveloperguy.com/capabilities/software-development#connections): Payments, email, forms and other services brought together, so people enter something once and it lands where it should. - [Work you can look at](https://thatdeveloperguy.com/capabilities/software-development#work): The TCB Fight Factory app is used by members and staff at a gym with locations in Rogers, Arkansas and Cassville, Missouri. It runs in a browser, installs to a phone, and is also packaged as an Android app and a desktop app. GrooveSteps, at groovesteps.com, offers free music practice tools that run in the browser, with accounts for the people who use them. - [How a software project runs](https://thatdeveloperguy.com/capabilities/software-development#process): Plan, build, test, ship: the four rows on the build board, in that order. You try working versions along the way. ## Service scope - Problem addressed: An organization has a job that off the shelf software does badly: members to manage, bookings to take, records to keep, a process that lives in spreadsheets and text messages. A custom app can fit the job, but only if someone scopes it honestly, builds it, and is still there to run it after launch. - Included: Mobile apps for Android and iPhone that install from the web, with app store listing when the project calls for it - Included: Web applications with accounts, records, payments and reports - Included: Desktop packaging for staff computers where the work calls for it - Included: The systems behind the app: sign in, databases, backups and monitoring - Deliverable: A written scope: what will be built, what will not, and how each part will be checked - Deliverable: Working versions you can try during the build - Deliverable: The source code and your content, with full rights to export both - Deliverable: A release record for every version: what changed, how it was checked, how to roll back - Not included: App store developer accounts and fees, which stay in your name - Not included: Operation after launch unless written into the engagement - Not included: Website design and IT support, which are separate capabilities with their own pages ## Questions - Do you build apps for both Android and iPhone? Yes. Our apps run on both. They install to the home screen straight from the web, which suits most business tools, and we add an Android package where it helps. Listing an app in the Apple App Store or Google Play is work we take on when a project needs it. - Who owns the app when it is finished? You do. Clients keep full rights to export their code and their content. - What does an app cost? It depends on what the app has to do. Request a briefing and we will scope it in writing before any work starts. - Do you build software for government buyers? Yes. ThatDeveloperGuy LLC works with government organizations and prime contractors. The Government Solutions page explains how that work is scoped. ## Related pages - [Websites](https://thatdeveloperguy.com/capabilities/websites) - [IT Services](https://thatdeveloperguy.com/capabilities/business-it) - [Government Solutions](https://thatdeveloperguy.com/government)
