The bottom line
Sensor Tower is a strong ASO tool for iOS, where batch keyword rankings and competitor keyword spying show which terms are worth targeting. Pair it with Mobile Action, which is more accurate on Google Play difficulty.
Key takeaways
- Sensor Tower's traffic and difficulty data is accurate on iOS, but weaker on Google Play difficulty. 1:13
- Mobile Action is more accurate on Google Play difficulty, so he pays for both tools.
- He prefers Sensor Tower's interface, and it is the longest-running tool he has used.
- Tracking a long keyword list shows which terms deserve a place in the name, subtitle and keywords field. 4:10
- For clients he builds lists of 100 to 200 keywords, sometimes 400, separated by commas.
- His plan allows 80 per app, so he deletes and re-adds the app for each new batch, then copies the data into a spreadsheet.
- Keyword spy shows which keywords a competitor ranks for that you do not. 7:47
- Comparing against Headspace surfaced terms such as chakra, happiness and a type of meditation he did not know.
- The tool only guesses from where apps rank well, and it can't see what a competitor actually targets.
- A keyword is worth targeting when the apps that rank for it are in your category. 9:30
- Headspace is third for chakra and the rest are meditation apps, so a Calm-sized app could reach the top five.
- The keyword "kami" returns games, so it is a poor fit even though a competitor ranks for it.
- For big clients like Calm he cares less about difficulty. A new client would skip a hard term like "meditation".
- The download and revenue estimates work as rough benchmarks, not exact figures. 3:00
- He says to take the numbers with a grain of salt, since they could be over or under.
- They are most useful for comparing similar apps, such as Headspace, Calm and Simple Habit, against each other.
If I'm looking at a keyword and seeing the top results and seeing that they're games, that might not be a keyword that I want to target.

Chapter summaries
0:00 Apple's Today tab shows what Apple features
Sensor Tower's Today view lets you see which apps Apple is featuring, and check whether you were one of them.
- The Today view lists featured apps in one place. 1:53
- Open Top Charts, then Featured, then Today.
- It shows only the past four days. Older data costs extra.
- It shows what Apple is focused on when it picks apps to feature.
- If downloads spike for no known reason, check here to see if you were featured.
2:37 The app overview adds competitor context
The overview page shows where a competitor's users come from and how it advertises.
- Overview data helps with competitive analysis. 3:04
- It shows reviews, all-time reviews and where the bulk of users come from.
- Calm's page shows it advertising on Instagram. More detail costs extra.
- A Sensor Tower co-founder estimated the downloads from his Page of free campaign accurately.
- He checked this on one of his own apps over a couple of days.
4:08 Keyword rankings in batches
Pasting a comma-separated list into the ASO section gives traffic and difficulty for every term at once.
- Commas keep multi-word phrases whole when you add keywords. 4:20
- A phrase like "train schedule" stays together when separated by commas.
- His demo list was meditation, calm and mindfulness.
- The keyword optimization tab splits phrases into single words.
- He used to paste lists there, but a phrase like "sleep stories" gets separated, so he no longer does.
5:36 Research, suggestions and translation
Keyword rankings is the workhorse, and the other tools fill small gaps.
- Keyword research gives traffic scores without tracking a term. 5:49
- Mobile Action has no such mode. It only shows data once a keyword is tracked.
- He uses it for one or two terms, like "sleep stories", when he only wants traffic data.
- The scores match what tracking gives, and he can start tracking from there.
- Keyword suggestions are too generic to rely on. 6:21
- Trying phrases can turn up long-tail terms, but the results are obvious.
- Other tools he showed earlier work better, so he mostly sticks to keyword rankings.
- The translation tool is a cheap way to localize a listing. 6:56
- It translates a phrase into many languages and shows character counts, so a VA can copy and paste.
- He tried it on a weak game that gets hardly any downloads.
- Traditional Chinese fits a lot of meaning into few characters.
7:47 Keyword spy in practice
Keyword spy is a source of ideas, and tracking each idea shows whether it is worth chasing.
- Keyword spy splits terms into those both apps share and those only the competitor has. 7:47
- He leaned on it heavily early on and now has other research tools.
- The gap list included odd terms like "Smart Watch", which may be localizations.
- Unfamiliar terms are added to tracking before judging them. 8:34
- He doesn't need to know a term's meaning to track it.
- In keyword rankings, the new terms all looked difficult.
- Traffic and difficulty scores rank the candidates. 10:16
- A traffic score of 3.4 is decent, and 2.8 has similar difficulty.
- He is already sixth for "kami", but the results are games.
