# iPhone and Android app development > We develop custom apps for iPhone and Android and take care of publishing them on the App Store and Google Play. If the app is for your team rather than the public, we suggest an installable web app: just as convenient, quicker to get and more affordable. Fixed price, tailored to your budget. - Page: https://estudiofase.com/en/app-development - Request a quote (no obligation): https://estudiofase.com/en#presupuesto - WhatsApp: +34 649 848 900 ## Who is it for? - **Businesses and start-ups that want their app on the stores**: An app anyone can download, with user accounts, in-app payments and notifications. We have our own apps published on both stores. - **Companies that need a tool for their team**: Sales reps, technicians, delivery drivers or warehouse staff: an installable web app that works without signal, without going through the stores or waiting for reviews. - **People with an idea who don't know where to start**: We help you decide what is really needed for the first version, so you can launch soon and grow with what your users ask for. ## What's included - One app for both iPhone and Android - Screen designs you try on your phone before anything is built - User accounts, sign in with Google or Apple - In-app payments and subscriptions - Notifications and offline mode - Web dashboard to manage content and users - Testing on real Android and iPhone devices - Publishing and store listings on the App Store and Google Play ## Pricing No fixed price list: highly competitive pricing, fixed before starting and adapted to the client's budget. ## App store app or web app: we help you choose What costs the most time and money with an app isn't building it: it's testing on lots of different phones and the Apple and Google reviews, which are repeated with every version. If your app is for the public to download, or needs phone features such as in-app payments, Bluetooth or NFC, it goes on the stores and we handle the whole process. If it's for your team, you often don't need the stores: an installable web app opens from a link, stays on the home screen like any other app, works without signal and every improvement reaches everyone instantly. That's how Catalenza works, the order catalogue used by sales reps on the road. ## Apps that are already on the stores We don't show you mock-ups: Cuentas Claras and DanZela are our own apps, published on the App Store and Google Play, with user accounts, payments, notifications and multiple languages. That experience (and those proven building blocks) is what lets us build your app faster and at a highly competitive price. ## And after launch A living app needs updates: new versions of iOS and Android, improvements your users ask for and replies to reviews. We stay with you after it is published. ## Related projects - **Cuentas Claras** (Shared expenses app): Split expenses between friends, flatmates and on trips.

It depends on what you need, which is why we don't have a fixed price list. What we can promise is a highly competitive price, fixed before we start. If you already have an amount in mind, tell us: we'll propose the best that can be done with it and, if needed, deliver it in phases. ### What happens if Apple or Google reject the app? We deal with it: we fix whatever they ask for and resubmit it until it is published. We know their rules well because we publish our own apps. ### Whose name is the app published under? We recommend publishing it with your own Apple and Google developer accounts, so the app belongs to you. We guide you through creating them and handle all the technical side. ### What is an installable web app (PWA)? It's an app that opens from a link and installs on the home screen without going through the stores. It works on iPhone, Android and desktop, even without signal, and is ideal for a company's internal tools. ### How long does it take to get the app? We give you a fixed deadline with the quote. We recommend launching a first version with the essentials and adding features later: you get there sooner and spend on what your users actually use. ### Who owns the project once it is finished? You do. The domain, the accounts and the content are registered in your name, and we explain how everything works so you don't depend on anyone.
