What each product offers, as listed by its team.

ASO.dev 5 features
Modular JavaScript 5 features
  • App Ads
    Explore detailed ad activity for any app on the App Store. Instantly view all active keywords, creatives, and Custom Product Pages (CPPs) tied to each campaign. Analyze which apps are buying which terms, and what visuals they use across all device types. Filter by country, compare strategies, and stay ahead of the competition with full visibility into Apple Search Ads.
  • Keywords Ads
    Find out exactly who’s advertising on any keyword in the App Store. Instantly see the apps bidding for that term, their ad creatives, and linked Custom Product Pages (CPPs). Explore ad visibility by country, and dive into visuals across device types. Perfect for uncovering competitors' strategies or spotting high-value keywords to target.
  • Competitors’ Keywords Ranking
    Hot Discover relevant keywords and compare your app's listing with competitors. Analyze keyword rankings across various countries and time periods, and monitor key metrics like Search Ads Popularity (SAP), difficulty, competing apps, and ranking trends. Enhance your app's visibility by leveraging competitors' successful strategies.
  • Subscription Pricing
    Optimize your app’s revenue. Manage prices in USD, choose rounded or charming price options, set fixed prices globally or apply multipliers like Netflix, Big Mac, and PPP (Purchasing Power Parity). Effortlessly edit prices in bulk with VAT adjustments, tailored for global markets by country tier.
  • Mass screenshot uploader
    Easily upload screenshots and videos individually or in bulk with simple folder selection - automatic device detection, perfect sizing, and correct order guaranteed!
  • Improved Code Organization
    Modular JavaScript allows developers to break down code into smaller, manageable modules. This enhances code readability and maintainability by organizing related functionality together.
  • Code Reusability
    Modules encourage reusability by allowing the same piece of code to be used across different projects or multiple areas of the same application, reducing redundancy.
  • Scalability
    As the application grows, managing code becomes easier with modular JavaScript. Each module can be developed, tested, and maintained independently, making the codebase more scalable.
  • Encapsulation
    Modules provide encapsulation, preventing variables and functions from polluting the global namespace. This reduces the risk of naming conflicts and bugs.
  • Improved Testing
    With code organized into discrete modules, writing unit tests becomes more straightforward. Each module can be tested individually, leading to more reliable and maintainable tests.

Possible disadvantages

  • Increased Complexity
    Introducing modularity can add complexity to the build process, as it often requires module loaders or bundlers (like Webpack or Browserify) to manage dependencies.
  • Overhead
    For smaller projects, using a modular approach might be overkill, introducing unnecessary overhead in terms of setup, configuration, and code management.
  • Learning Curve
    Developers unfamiliar with modular JavaScript may face a learning curve, especially when dealing with module patterns, loaders, and bundlers.
  • Dependency Management
    Relying on multiple modules can lead to complex dependency chains, making it challenging to track and resolve dependencies across different modules.
  • Performance Overhead
    Modular JavaScript can introduce performance overhead if not managed properly, such as loading many small modules individually, leading to increased HTTP requests.

Questions & Answers

As answered by people managing ASO.dev and Modular JavaScript.

What makes your product unique?

ASO.dev's answer

ASO Toolkit with NO limits on keywords or apps made by developers for developers

How would you describe the primary audience of your product?

ASO.dev's answer

We build ASO.dev for everyone who manages apps on the App Store - from independent developers to major mobile publishers. Whether you run a single app or a whole portfolio, we help you automate the repetitive work and focus on what really drives growth.

Why should a person choose your product over its competitors?

ASO.dev's answer

ASO.dev gives you complete freedom - no limits, no restrictions. You can track unlimited keywords, apps, and developer accounts. All the keywords your apps rank for are automatically collected into a single, unified list - you don’t need to search or guess which ones matter.

Our automation tools handle repetitive App Store Connect tasks like metadata editing, bulk uploads, translations, and screenshots - saving hours every week for developers and marketing teams. Unlike most tools, ASO.dev combines keyword tracking, metadata management, reviews, and Apple Search Ads insights in a single dashboard, designed for both indie developers and large publishers.

In short: ASO.dev saves time, removes limits, and gives you full control over your App Store growth.

What's the story behind your product?

ASO.dev's answer

ASO.dev was born from our own experience and frustration. After translating our app into 39 languages, we got tired of manually filling out What’s New, managing screenshots, and guessing which keywords users were searching for. We wanted a tool that would simply show all the keywords our app ranked for - and automate everything else.

So we built it ourselves. What started as a small tool quickly grew into a full platform - designed, coded, and scaled entirely by two people, bootstrapped from day one.

Today, ASO.dev helps developers and companies of all sizes save time, automate App Store workflows, and focus on growth instead of routine.

Built from our own pain, grown by passion - and still 100% bootstrapped.

Which are the primary technologies used for building your product?

ASO.dev's answer

  • Flutter (multi-platform: macOS, Windows, iOS, Andoid)
  • .NET Core (C#) for API services and integrations
  • MongoDB for app data and user state
  • RabbitMQ for distributed task processing and queue management
  • Kubernetes
  • Rancher
  • Hosted on Hetzner
  • Data backups stored on S3-compatible storage
  • Apple App Store Connect API (metadata, screenshots, in-app events, pricing, etc.)
  • Stripe & RevenueCat for subscription management
