ASO Tool Comparison
RespectASO vs ASO.dev: Which ASO Tool Is Right for Indie Developers?
Compare RespectASO and ASO.dev for iOS keyword research. Local-first desktop vs. hosted metadata workspace: architecture, free edition, scoring approach, MCP, and Pro AI workflows.
What Is ASO.dev?
ASO.dev is a hosted ASO platform for app developers, paired with an App Store Connect companion iOS app for managing metadata. It covers keyword research and metadata workflows for the App Store and Google Play, and its site describes an AI Companion (MCP) for working with ChatGPT, Claude, and Cursor.
ASO.dev sits in the same indie-friendly part of the market as RespectASO, which means the comparison is more about workflow choice than about a stark feature gap.
Fundamental Differences
RespectASO is built for developers who want local-first iOS keyword research, transparent scoring, open-source core tooling, and Pro agentic AI workflows for niche research, competitor analysis, and metadata simulation. ASO.dev is designed around a hosted research-and-metadata workspace for app developers.
| Aspect | ASO Dev | RespectASO |
|---|---|---|
| Architecture | Hosted web platform with an App Store Connect companion iOS app | Desktop app (runs locally on your Mac), plus Docker self-host |
| Primary focus | ASO research and metadata management | iOS keyword research, scoring, country opportunity, and metadata workflows |
| Store coverage | App Store and Google Play | iOS App Store |
| Free tier | Free trial; paid subscription tiers | Full open-source free edition (AGPL-3.0) |
| Pricing model | Recurring subscription | Free open-source + optional annual Pro license (see pricing) |
| Open source | Commercial product | AGPL-3.0 (free edition) |
| Data residency | Hosted research workspace | Free core research runs locally with no RespectASO account or telemetry |
| Country research | Keyword research across App Store locales | Country Opportunity Finder scans and ranks all 30 storefronts in one background pass |
| AI workflows and MCP | AI Companion (MCP) for ChatGPT, Claude, and Cursor; AI review replies | Pro agentic AI (Niche Researcher, Competitor Analyzer, Score Simulator) with any cloud or local model (BYOK), plus a first-party MCP server with 23 ASO tools |
Key Differences
Hosted Workspace vs. Local-First Architecture
ASO.dev stores your research and metadata work in its hosted workspace. RespectASO is local-first by architecture: the keywords you research, the apps you track, and your search history all live in a local database on your machine, with no RespectASO account or telemetry. The privacy-first ASO tool page lists every outbound network call - iTunes Search, GitHub release check, optional LLM provider for Pro AI, and license verification - so the data and network behaviour is fully visible.
Subscription vs. Open-Source Free Edition
ASO.dev offers paid subscription tiers with a trial. The RespectASO free edition is the open-source core app under AGPL-3.0 with the source on GitHub. You can read the code, run it as a Mac app, or self-host with Docker via the included docker-compose.yml. The open-source ASO tool page explains the AGPL community fork and how it relates to Pro.
Country Opportunity Scanning
For indie iOS developers, the country choice is one of the most important launch decisions. RespectASO's Country Opportunity Finder scans all 30 supported App Store storefronts at once for a single keyword and ranks them by opportunity score. That makes it practical to find tractable launch markets for an app that can't fight US Top 5 from day one.
Two MCP Stories, Different Data
Both tools connect to AI assistants. ASO.dev describes an AI Companion (MCP) for metadata automation with ChatGPT, Claude, and Cursor. RespectASO Pro ships a first-party MCP server with 23 ASO tools that work against your own local research database - keyword scoring, opportunity scans, Top Search Terms, and the three agentic AI workflows: AI Niche Researcher, AI Competitor Analyzer, and ASO Score Simulator. Pro is BYOK with any cloud model, or a local model via Ollama or LM Studio.
RespectASO's Advanced Strengths
Recent RespectASO releases added a set of capabilities that matter in any ASO tool comparison:
- Official Apple popularity data (free): connect a free Apple Ads API key once - no campaigns, no ad spend - and RespectASO syncs Apple's official weekly search-popularity dataset from the Apple Ads Platform API to your machine. You choose whether Apple's values or the built-in estimate power your scores, and the key never leaves your computer. How the two sources work.
- A calibrated estimate: the built-in popularity estimate is fitted against hundreds of Apple's official search-popularity values - rank correlation 0.61 with Apple's data on held-out keywords, and 0.71 on brand-like keywords where the previous weights scored 0.09.
- Top Search Terms (Pro): browse Apple's official most-searched terms per storefront and category - up to 500 terms across 15 categories with rank, popularity, weekly climbers and fallers, and brand-new entries. Track any term or send it to the AI Researcher in one click.
- A first-party MCP server (Pro): all 23 ASO tools are usable from Claude Desktop, Claude Code, Cursor, VS Code, and other MCP clients - your assistant scores keywords, runs opportunity scans, and drives the AI workflows against your own local research data. MCP setup.
- Any AI model, any provider (Pro): type any model ID from OpenAI, Anthropic, Google Gemini, or OpenRouter - the in-app test is the only gate, so new models work the day they ship. Or skip the cloud entirely and run a local model via Ollama or LM Studio with no per-query cost.
- Source-aware AI reports (Pro): every AI analysis states which popularity source produced its numbers, and saved reports freeze their figures so the text and the numbers always match. See everything in Pro.
Where the Hours Go
Manual keyword research is slow in a very specific way: checking one keyword in one storefront means an App Store search, a scroll through the results, and notes on the top apps - a few minutes every time, multiplied by every keyword and every country you care about. RespectASO automates exactly that arithmetic. One search scores up to 20 keywords across 5 storefronts in a single run, and the Country Opportunity Finder checks a keyword across all 30 supported storefronts in one background pass - research that would otherwise cost an afternoon of storefront-by-storefront checking.
The rest of the routine runs itself: tracked keywords refresh automatically every day, Apple's official top-terms dataset syncs weekly so popularity lookups are instant and local, and bulk actions apply to your whole selection even across pages. With Pro, the AI Niche Researcher turns one seed keyword into 50-70 scored candidates plus ready-to-test metadata in a single run, and through MCP your AI assistant runs the same research mid-conversation - no app switching, no copy-pasting scores.
When RespectASO Is the Better Fit
- You want privacy that's a property of the architecture — local SQLite, no account, no telemetry — and a fully published list of outbound network calls.
- You want Apple's official search-popularity data powering your scores, synced weekly through your own free Apple Ads key.
- You want an open-source free edition you can inspect and either run as a Mac app or self-host with Docker.
- You want Country Opportunity Finder to pick launch markets across many storefronts at once.
- You want Pro agentic AI workflows for niche research, competitor analysis, and metadata simulation with BYOK - any cloud model, or a local one via Ollama or LM Studio.
- You want a free edition that's the full free edition rather than a trial.
When ASO.dev Is the Better Fit
- You prefer a hosted product you can open from any device without installing a desktop app or running Docker.
- You want an App Store Connect companion app for managing metadata from a hosted workspace.
- You publish on Google Play as well and want both stores in one subscription.
The Bottom Line
ASO.dev is a hosted ASO platform with metadata management and an AI Companion (MCP). RespectASO is a local-first iOS keyword research and metadata workflow with Apple's official popularity data available at no cost, an open-source free edition, the Country Opportunity Finder for launch-market selection, and Pro agentic AI workflows that compress the research-to-metadata cycle.
