Custom app development studio

Custom apps for Android, Windows, and the web.

We design and build native and cross-platform apps for small teams and growing businesses. Fixed-price quotes, weekly demos, and no outsourcing — every project is built in-house from kickoff to launch.

What we build.

Four kinds of projects we are good at. If yours is not on the list, ask anyway — we will tell you honestly if we are the right fit.

Android apps

Native Android apps built with Kotlin and Jetpack Compose, or React Native for cross-platform delivery. Designed to be fast, offline-friendly, and respectful of battery and data.

What is included

  • Kotlin / Jetpack Compose or React Native
  • Google Play submission and store listing
  • Offline-first architecture, minimal permissions
  • Hardware integration (camera, sensors, files)

Best for: Mobile utilities, content apps, internal tools, field service apps.

Desktop apps

Modern desktop apps for Windows, macOS, and Linux — built with Tauri, not Electron. Installers under 10 MB, instant startup, and your users never see a browser chrome.

What is included

  • Tauri (Rust + Web frontend) — not Electron
  • Windows MSI / Microsoft Store, Mac DMG, Linux AppImage
  • System integration (notifications, tray, files)
  • Code-signing and auto-update setup

Best for: Productivity tools, creative apps, internal dashboards, utilities.

Web apps

Server-rendered React apps with Next.js, designed to load fast, work on slow connections, and rank well in search. Includes authentication, databases, payments — the full stack.

What is included

  • Next.js (App Router) with React Server Components
  • Authentication, payments, and email set up for you
  • Accessible by default — keyboard, screen-reader tested
  • Deployed to your hosting (Vercel, Appwrite, your VPS)

Best for: SaaS products, internal portals, marketing sites with real functionality.

App modernization

Already have an app but it is slow, bloated, or held together with duct tape? We audit your codebase and ship focused upgrades — smaller bundles, faster startup, fewer crashes, modern UI.

What is included

  • Performance audit (bundle size, startup, memory)
  • Migrations: Electron → Tauri, jQuery → React, etc.
  • Dependency upgrades and security patches
  • Working code on day one, not a 6-month rewrite

Best for: Legacy desktop apps, slow web apps, "we need to ship this update" situations.

How we work.

No surprises, no scope-creep, no disappearing for a month. Here is what working with us looks like, week by week.

  1. 01

    Discovery call

    A free 30-minute video call. You tell us what you are trying to build, we ask questions, and we figure out together if we are the right fit. No pitch deck, no obligation.

  2. 02

    Fixed-price proposal

    Within a few days, you get a written proposal with a clear scope, a fixed price, a realistic timeline, and a list of what is included. The price you see is the price you pay.

  3. 03

    Build, in weekly demos

    We work in one-week sprints. Every Friday you get a demo video showing what was built. You give feedback, we adjust. You see the project grow in real time — no six-month black box.

  4. 04

    Launch

    When the app is ready, we handle store submissions, deployment, code-signing, and the boring technical paperwork. You get a hand-off document explaining everything and the source code.

  5. 05

    30 days of included support

    After launch, we fix any bugs that come up — for free, for 30 days. After that, you can keep us on for ongoing maintenance, or take it from there with our docs.

What we work with.

Modern, proven tools. Nothing exotic, nothing experimental on your dime. If a framework has not been around for at least a few years, we are not building your project on it.

Apps we have shipped.

We eat our own cooking. Every AbeSoft product is built with the same stack and approach we use for client work — and each one started as a tool we wanted to use.

About AbeSoft.

AbeSoft is a focused software studio. Every project — from initial discovery to final deployment — is owned end-to-end. There is no account manager layer, no hand-off to a different group, no "let me check with someone".

We take on a small number of client projects each year, alongside our own products. That means every engagement gets real attention. It also means we sometimes say no — if we cannot do great work on your project in our current schedule, we will tell you upfront rather than overpromise and underdeliver.

We work in plain English. We write fixed-price proposals. We send weekly demos. We answer our email. None of this is special — it is just what working with a studio should feel like.

Tell us about your project.

Fill in the form below — takes about a minute. We will reply within one business day. Or, if you would rather just email us directly, that works too.
