what step counter reviews are about
We read 7,859 App Store reviews of 10 iPhone step counters and counted what they talk about. Not whether the apps are good — what their reviewers chose to write about, split by the rating they left. The file is public, machine-readable and free to reuse with credit.
What only shows up once they're counted
- What splits the ratings: losing history appears 5.7× more often in 1-2★ reviews than in 5★ ones — 4.6% against 0.8%.
- What everyone brings up either way: step-count accuracy, 16.4% of 1-2★ reviews and 11.3% of 5★ ones — the subject raised most often in both bands at once, by people who liked the app and by people who did not.
- The single largest complaint is wearables and watches at 17.8% of 1-2★ reviews; the most common praise is motivation at 15.4% of 5★ ones.
Every theme, by the rating people left
Each cell is the share of reviews in that band that talk about the theme. One
review can talk about several, so a column does not add up to a hundred. The 3-4★ band is
shown but takes no part in the comparison above — that is how the method defines it.
The code beside a name is its value in the theme column, shown where the two
differ.

How it was measured, and what that costs
This is not a random sample, and the limit is Apple's rather than ours.
Apple chooses the order — mostHelpful is its own ranking — and the store caps
the feed at 500 records per app per sort order. This collection hit that cap, so the largest
apps are truncated to 500 out of hundreds of thousands. Read the shares as
what the reviews the store shows first talk about, not as what the market thinks.
The labeling is manual. Themes are matched by a hand-written dictionary of phrasings, not by a model. What is reproducible is the procedure, not a truth about the category. 8,492 records were collected and de-duplicated down to 7,859 unique ones — people edit their reviews, so the same review can arrive twice with different endings.
The ten apps were not picked at random either. Nine were taken by number of ratings; one was taken for position rather than weight — Steps — Simple Pedometer, the only app in the category leading its first screenshot with a lock screen widget.
Using it
The file itself is step-counter-reviews.json — 630 rows of app × theme × band, plus the same counts rolled up across apps — or step-counter-reviews.csv, the flat form. The rolled-up figures are not lost in the CSV: every one of them is the sum of the rows that are in it.
Every row carries its app_store_id, which is the same key used by
the store-listing survey — so the two datasets join, and six of the ten
apps here appear in both. The four that don't are not an oversight: the two datasets were
selected on different grounds, and that is what makes the pair honest.
What is not in the file is any review. No text, no author, no per-review record — only counts. That matters for what we can license: the reviews were written by App Store customers and belong to them. What we publish is the compilation, its structure, the theme dictionary and the method, under CC BY 4.0, with credit to Angel Step, angelstep.app/data/review-themes.

Who made it
Angel Step is a step counter for iPhone built around one number, with widgets for the home and lock screen. Angel Step is on its way to the App Store, so it is not one of the ten apps counted here — an app with no reviews cannot be in a dataset about reviews.
That is also why nothing on this page ranks anything. A participant scoring its own market is an advertisement, and these counts are meant to hold up for someone who has never heard of us.
