Part 02 · Top three

Our top three

The three we'd look at first, and who each one suits

The three app store optimization tools we'd look at first. First place suits the most people; second and third are the best picks for the people it leaves out. Each has an Insider's Guide of its own.

1. 1st

   

   2.6GPA

   Asodesk

   Free plan · from $47/mo

   For: Most app developers and small app teams

   Asodesk covers the App Store and Google Play: keyword research with daily impression estimates, a position table with Search Ads popularity, a metadata optimizer, competitors' positions and top charts, and 100 review replies a month. The free plan keeps 1 app, 200 keywords and 1 teammate, and the 7-day trial needs no card. Know the limits: Pro is $47 a month billed annually ($59 monthly) for only 2 apps and 700 keywords, optimizer export and the full alerts need Guru at $159, the organic installs report needs Power at $343, and it runs in a browser only.

   2.6GPA

   AsoBeast

   Free plan · from $10/mo

   For: Developers tracking several apps for a few dollars

   AsoBeast checks keyword positions daily to position 200 on the App Store and Google Play in every country you add, flags the day a rival changes its title or icon, and ranks fixes in a task list, with an API and MCP server. Hosted Indie is $10 a month for 5 apps and 1,000 keyword markets, or the AGPL code is free to run yourself with Docker. It is second because there is no free hosted plan after the 7-day trial, a keyword market is one keyword in one country, the next plan jumps to $99, and there is no uptime guarantee.

   3.0GPA

   RespectASO

   Free plan · from ₹1,800/mo

   For: iOS developers on a Mac who want to pay nothing

   RespectASO is a free, open-source Mac app that researches App Store keywords in 175 storefronts, with popularity and a 1 to 100 difficulty score, a country opportunity finder, the top 10 apps per keyword and daily rank tracking, all kept on your Mac with no account. Pro is a one-off licence for 3 or 12 months, priced in local currency. It is third because it covers the iOS App Store only, with no Google Play research. Pro runs only on Apple Silicon Macs, a Docker edition for Linux and Windows has the free features alone, and Pro's AI tools need your own paid API key or a local model.

   The RespectASO Insider’s Guide

Going by our grades, FoxData, RespectASO, ASOTools and AndroidRank give the most for the money among app store optimization tools: no tool on this chart scores higher without costing more.

Paid plans start at a middle price of $19 a month across the 34 that charge, from $6.20 (RespectASO) to $896.48 (Geeklab). 2 more cost nothing at all.

10 of the 36 score above the category's average while starting at or below its middle price. 3 cost more than the middle price and score below the average.

Every tool gets five grades, A to F, each with its reason, and a GPA that averages them. Here are the 12 highest graded app store optimization tools, then how the whole category does on each subject.
