**Best mobile app development company: five firms that build one app for iPhone and Android, compared on prices, timelines and Clutch data. Checked Oct 22, 2026.**
**Disclosure:** App369 publishes this guide and is one of the five companies listed. It compares what each company publishes on its own website (checked October 22, 2026) and its public Clutch profile (read October 15, 2026). It is not an independent benchmark.
## Key takeaways
- →App369 publishes this guide and is one of the options. It is based on public information, not an independent benchmark.
- →All five build one app for iPhone and Android from a single codebase, in Flutter or React Native, which can cost less than two separate native apps, depending on the app.
- →Published starting points range from $5,000 (SolGuruz minimum) and $9,000 (App369) to $40,000 for a simple one-platform app (Cleveroad cost guide).
- →Several firms publish one minimum on their own site and another on Clutch, so get the price for your scope in writing.
- →Clutch review counts range from 17 (Ptolemay) to 82 (Cleveroad); App369 shows 126 Fiverr reviews instead of a Clutch profile.
- →Ask for App Store and Google Play links to apps the company built, not just screenshots.

## What a mobile app development company is (and isn’t)
A mobile app development company designs, builds and launches apps for iPhone and Android: the screens, sign-in, the database behind the app, payments and the App Store and Google Play listings. This guide covers companies that build one app for both platforms from a single codebase, in Flutter or React Native. That can cost less than building two separate native apps, depending on the app. For iPhone-only or Android-only apps, see the [iOS](https://app369.com/blog/best-app-development-company-ios-2026/) and [Android](https://app369.com/blog/best-app-development-company-android-2026/) guides. For what App369 builds, see the [mobile app development service page](https://app369.com/service/mobile-apps/).
## How I compared these mobile app companies
I checked each company’s own website on October 22, 2026, and its Clutch profile on October 15, 2026:
- **Published price:** a starting price, minimum or cost band on the company’s own site.
- **Published timeline:** how long the company says a first version takes.
- **Clutch data:** minimum project, hourly rate, rating and review count, read the same day.
- **Cross-platform stack:** whether the company names Flutter or React Native.
- **Proof of work:** named clients, case studies or apps in the stores.
I didn’t hire these companies or test their apps. Companies are listed alphabetically. The order is not a ranking.
## The best mobile app development companies in 2026
### 1. App369, best for a first iPhone and Android app at a fixed price
App369 publishes this guide. It is one developer, Simon Dziak, in Miami, Florida. It builds [mobile apps](https://app369.com/service/mobile-apps/) in Flutter, so one codebase runs on iPhone and Android, with Firebase or a Node.js backend on Google Cloud. Mobile apps start from $9,000, and the [instant quote](https://app369.com/instant-quote/?need=mobile) gives a price range for your features in about a minute before a written fixed quote. Its own product, Workspace369, is a Flutter and Firebase app, described in the [Workspace369 case study](https://app369.com/case-studies/workspace369/). App369 has no Clutch profile; its Fiverr profile shows a 5.0 rating from 126 reviews (read October 13, 2026).
- **Strengths:** a published starting price for a two-platform app; you work directly with the developer; a fixed written quote before you commit.
- **Limitation:** one developer, so it can’t run a large build or several workstreams at once.
- **Best for:** founders and small businesses who want a first app on both stores without an agency budget.
### 2. Cleveroad, best for businesses that want a large team with a long review record
Cleveroad’s site lists offices in Tallinn, Estonia, Claymont, Delaware, and Oslo, Norway. It builds native iOS and Android apps as well as Flutter and React Native apps. Its own cost guide puts a simple app for one platform at $40,000–$120,000 over 2–3 months and a medium app at $120,000–$200,000 over 3–6 months. On Clutch it lists a $10,000+ minimum project and $25–$49 per hour, with a 4.9 rating from 82 reviews and 250–999 employees (read October 15, 2026).
- **Strengths:** the most Clutch reviews here; low hourly rates; published cost bands by complexity.
- **Limitation:** its cost bands are quoted for one platform and sit far above its $10,000+ Clutch minimum, so ask for a two-platform quote.
- **Best for:** businesses that want a large vendor with a long public review record.
### 3. nomtek, best for funded startups that want Flutter with big-brand references
nomtek lists its address in Wrocław, Poland, on its own site. It builds native and multi-platform apps, with Flutter, FlutterFlow and augmented reality work named on its site. Its home page names projects for Randstad, where it reports active users up 57% from 2023 to 2024, Siemens Healthineers, Slyyd and Vogue Singapore. Its pricing page describes fixed-price, time-and-materials and dedicated-team models with no dollar figures. On Clutch it lists a $25,000+ minimum project and $50–$99 per hour, with a 4.9 rating from 43 reviews (read October 15, 2026).
- **Strengths:** well-known named clients; a Flutter specialty; a fixed-price option.
- **Limitation:** no published price, and a Poland base means less overlap with US working hours.
- **Best for:** funded startups and larger companies that want a Flutter team with enterprise references.
### 4. Ptolemay, best for consumer apps built in Flutter with a US contact
Ptolemay shows its address at 340 S Lemon Avenue in Walnut, California, on its site. It builds Flutter apps and says it puts 2–3 senior engineers on each project. Its home page features consumer apps including Sézane, a fashion app, Diagnio, a fertility tracker, and Ranny, a rentals marketplace, with their store ratings. On its own blog it lists itself as “starting at $10,000, $50/hr”. On Clutch it lists a $25,000+ minimum project and $50–$99 per hour, with a 5.0 rating from 17 reviews (read October 15, 2026).
- **Strengths:** real consumer apps with large rating counts; a US address; small senior teams.
- **Limitation:** its $10,000 start, from a ranking it wrote itself, conflicts with its $25,000+ Clutch minimum.
- **Best for:** consumer, e-commerce and health startups that want Flutter and a US point of contact.
### 5. SolGuruz, best for small budgets that want a published rate and minimum
SolGuruz says on its site that it is headquartered in Ahmedabad, India, with 90+ people. It builds mobile apps in Flutter, React Native and native code, plus web and AI work. Its home page FAQ publishes the most complete price set here: $18–$50 per hour, a $5,000 minimum project, and about 8–12 weeks from contract to App Store submission, with fixed-price, hourly and dedicated-team options. Its featured case study is a hospitality maintenance platform delivered in 45 days. I couldn’t read its Clutch profile on October 15, 2026, so this guide has no Clutch figures for it.
- **Strengths:** a published hourly rate, minimum and timeline; the lowest published minimum here; a fixed-price option.
- **Limitation:** no US office found on its site, and no Clutch figures I could check.
- **Best for:** small budgets that want an offshore team with clear rates up front.

## How to choose a mobile app development company
1. **Decide on one codebase or two.** One Flutter or React Native app can cost less than separate iPhone and Android apps, depending on the app. The [native vs cross-platform comparison](https://app369.com/compare/native-vs-cross-platform/) shows when native is worth it.
2. **Ask for store links.** Ask for App Store and Google Play links to apps the company built and still maintains.
3. **Compare written quotes for the same scope.** The [app development RFP guide](https://app369.com/blog/complete-guide-app-development-rfp-2026/) helps you describe it once for every firm.
4. **Check minimums in writing.** Several firms above list different minimums on their site and on Clutch.
5. **Own everything after launch.** The [mobile app handoff checklist](https://app369.com/blog/mobile-app-handoff-checklist/) lists the code, accounts and store listings you should receive.

## **Frequently asked questions**
- **What is the best mobile app development company for a startup?**
- It depends on budget and how much help you need. App369 and SolGuruz publish low starting prices, nomtek and Ptolemay show well-known consumer apps, and Cleveroad offers a large team. App369 publishes this list, so compare at least two.
- **How much does a mobile app cost in 2026?**
- Published starting points here run from $9,000 for an App369 Flutter app for iPhone and Android to $40,000–$120,000 for a simple one-platform app in Cleveroad's cost guide. SolGuruz lists a $5,000 minimum project.
- **Should I build with Flutter or React Native?**
