RankASO is the ASO app for iPhone. Every morning it checks each keyword you track against the public App Store search, to position 200, in every storefront you choose, and shows what moved before you have finished your coffee. It tracks your rivals from the same searches, tells you which words in your keyword field earn a rank and which carry nothing, and gives every keyword a verdict you can act on. There is no sign-up and nothing is collected. The free plan tracks one app and 30 keywords.

Why the phone

Every other ASO tool is a website or a desktop app. That made sense when ASO was a research task you did at a desk twice a year. It makes no sense for the thing you actually do every day, which is look at what changed. Ranks refresh overnight. The phone is in your hand at breakfast. A widget on the home screen with yesterday's movement is the whole daily check, and a dashboard you have to log into is the reason the check gets skipped.

The second reason is privacy. A phone app can do all of this with no account, because the phone reads the public App Store directly. Your keyword list is your strategy, and with RankASO it stays on your phone and in your own iCloud.

What it does

  • Daily ranks to 200. Each keyword is checked once a day per storefront at a consistent time, so day-to-day movement is real movement. A missed day is shown as missing, never filled in.
  • Rivals from the same result. Add a competitor and every check reads their position from the same search as yours. Gaps lists the terms they rank for and you do not. If a rival leaves the store, you hear first.
  • The wall. For each term, the top 10 apps with their rating counts, a difficulty score, and a one-word verdict: Go for it, Climbable, Long shot, Skip. Tap any score and the facts behind it are listed.
  • The field report. Studio reads your name, subtitle and keyword field and shows, word by word, which words earn a rank somewhere and which carry nothing. The rule checker flags wasted characters as you type; the optimizer writes a field from the terms you already win.
  • Goals and alerts. Set a target rank on a keyword and watch the distance close. Alerts arrive when you enter the top 10, leave it, make a big move, or a rival disappears. Nothing on quiet days.
  • A Today screen and a widget. One number for how much of your tracked demand you hold, your goals, and what moved.
  • Apple Ads, if you have it. Connect your own account and your keywords show Apple's demand figure beside RankASO's estimate, each clearly marked. Optional.

Free and Pro

Free tracks one app, 30 keywords, two storefronts, three research lists, ten Discover seeds a day, Studio and the rule checker, and shows 90 days of history. Pro adds unlimited apps and rivals, 175 storefronts, history forever, removal watch and the optimizer. The paywall appears only when you reach a real limit, never on launch and never on a timer. Prices are set per country by the App Store and shown in the app.

Questions

Where do the ranks come from?

From the public App Store search for each storefront, the same results a new user sees. RankASO reads your position to 200 and every rival's position from the same result.

Why do my ranks differ from what I see in the App Store app?

The App Store you see is personalised to your phone. RankASO reads the neutral result for a storefront, which is what a stranger sees. Small differences are normal.

Does it work on iPad or Mac?

It is an iPhone app. Exports in CSV and JSON are one tap away if you want the data on a desk.
