# ASO Agency

> ASO Agency is a specialist App Store Optimization team that helps funded mobile startups rank higher, convert more store visits into installs, and grow organic installs on the App Store and Google Play. Month-to-month, no long-term contracts.

Services: ASO audit & strategy, keyword & metadata optimization, conversion rate optimization (icons, screenshots, video), ratings & reviews management, Apple Search Ads, and localization for 30+ markets. The App Store and Google Play are treated as two distinct systems with separate playbooks.

Content is written and reviewed by the agency's practitioners. Every statistic carries a named source and a retrieval date; posts are revised as the stores change. See the editorial standards page for the full methodology.

## Free tools
- [App Store keyword rank checker](https://asoagency.io/keyword-rank-checker): Enter a keyword, pick any of 50 App Store country storefronts, and optionally add an app (by name, App Store link, or numeric ID) to see the live top 200 search results for that keyword with the app's exact rank highlighted. Data comes straight from Apple's public iTunes Search API — the same catalog and relevance engine behind App Store search, without Search Ads placements or personalization, so ranks are a reliable directional baseline. Shows each result's icon, name, developer, and rating; keeps a session history of checked keyword ranks; supports shareable deep links (?k=keyword&c=country&a=app). Apple App Store only (Google Play has no public search API). Queries go from the browser directly to Apple; nothing is stored.
- [App review keyword analyzer](https://asoagency.io/app-review-analyzer): Enter any iOS app (name, App Store link, or ID) and a country, and the tool pulls up to 500 of its most recent App Store reviews from Apple's public customer-reviews feed (10 pages of 50 — Apple's limit) and analyzes them in the browser: average rating of the sample, 1–5 star distribution, share of positive (4–5★) vs negative (1–2★) reviews, and the words and 2–3 word phrases users repeat — split into terms praised in positive reviews and complained about in negative ones, ranked by how many reviews mention them. Click any term to read the underlying review excerpts with the term highlighted. Works for competitors' apps too; per-country feeds across 50 storefronts; supports deep links (?a=app&c=country&n=pages). Apple App Store only (Google Play has no comparable public feed). No backend — nothing is stored.
- [Apple Search Ads calculator](https://asoagency.io/apple-search-ads-calculator): Four live calculators for Apple Search Ads (Apple Ads) campaign math. Campaign cost breakdown: spend, taps, installs and optional impressions → CPT (spend ÷ taps), CPA (spend ÷ installs), tap-to-install conversion rate, and TTR (taps ÷ impressions), with a verdict against the ~60% conversion rate typical of Apple Ads. Break-even bid: revenue per install (ARPU/LTV in a payback window), conversion rate, and target ROAS → the maximum CPA and maximum CPT bid that hit the target (break-even CPT = revenue per install × conversion rate ÷ target ROAS). ROAS & profit: spend and attributed revenue → ROAS percentage and net profit or loss, judged over a defined revenue window. Budget planner: target installs, expected CPT and conversion rate → taps needed, budget required, implied CPA. All computation happens in the browser; nothing entered is uploaded or stored.
- [App Store cross-localization explorer](https://asoagency.io/app-store-localizations): Pick any of 175+ App Store country storefronts and see every localization Apple indexes for keyword search — the primary (default) language plus the secondary localizations whose 100-character keyword fields also rank there. For example the U.S. indexes 10 localizations (English U.S. plus Arabic, Chinese Simplified/Traditional, French, Korean, Portuguese-BR, Russian, Spanish-MX and Vietnamese). Includes a full searchable reference table and how cross-localization works.
- [Metadata character counter](https://asoagency.io/metadata-character-counter): A live character counter for every App Store and Google Play metadata field with the exact limit for each — App Store: app name 30, subtitle 30, keywords 100, promotional text 170, description 4,000, What's New 4,000; Google Play: title 30, short description 80, full description 4,000. Flags which fields are indexed for search (App Store: name, subtitle, keywords; Google Play: all three) and warns when a field is near or over its limit. Runs entirely in the browser.
- [Keyword field optimizer](https://asoagency.io/keyword-field-optimizer): Paste a list of App Store keywords in any format — separated by spaces, commas or new lines — and the tool rewrites it into a single clean, comma-separated, space-free keyword field. It removes the spaces (Apple wants commas only), splits multi-word phrases into individual words (Apple combines single words automatically), removes duplicate keywords (case-insensitive) and trims the result to fit Apple's 100-character keyword field, keeping your keywords in priority order and showing which terms were left out. Copy the result straight into App Store Connect. Runs entirely in the browser.
- [Keyword density checker](https://asoagency.io/keyword-density-checker): Paste a Google Play description or any app store metadata and see the most-emphasized keywords and 2- and 3-word phrases ranked by density (share of total words), with word, unique-word and character counts. Flags single words above ~5% density as keyword-stuffing risk and can ignore common function words. Explains that density is a Google Play signal (the full description is indexed) but not an iOS one (Apple doesn't index the description and counts each keyword once, so coverage matters more than repetition). Runs entirely in the browser.
- [Store page preview](https://asoagency.io/store-page-preview): Enter your app name, subtitle, icon and screenshots and see how the listing renders in the App Store and Google Play — both the search result and the product page — with realistic truncation. Switch between stores (App Store shows icon, name, subtitle, rating and first screenshots; Google Play shows icon, title, developer, rating and a feature image) and between search-result and product-page views. Shows where the name and subtitle get cut off before the 30-character limit and how the first two or three screenshots look in the gallery. The icon and screenshots are read locally with FileReader and never uploaded; everything runs in the browser.
- [Keyword shuffler](https://asoagency.io/keyword-shuffler): A keyword phrase mixer for ASO research. Enter up to four words and the tool generates every 1-, 2-, 3- and 4-word phrase in every order (permutations, so order matters and both "fitness home" and "home fitness" appear), grouped into columns by phrase length — four words yield 4 + 12 + 24 + 24 = 64 phrases. Duplicate words are ignored and columns are only built up to the number of words entered. Select the relevant phrases (per-row, per-column select-all, or global select all/clear all), then export the selection to a CSV (with a word-count column) or copy it to the clipboard. A Shuffle button randomizes the display order within each column. Everything runs in the browser; nothing is uploaded.
