How do you see a Chrome extension’s user count history?
On the Trends tab of the extension’s page in AppView, for any extension, not only your own. Three tiles at the top show the current user count, rating and review count, each with its change over the last 30 days and a small line. Click a tile to open its full chart below, where you pick the period and turn release dates on or off.
Where else you can see these numbers depends on whose extension it is:
| Who you are | Where to look | What you see |
|---|---|---|
| The extension’s developer | Chrome Web Store Developer Dashboard | Installs, uninstalls, impressions and weekly users, for your own extensions only |
| Anyone | The extension’s store page | Today’s user count, rating and review count, with no history |
| Anyone, for any extension | AppView Trends tab | Users, rating and reviews over time, with release dates |
This is a working copy of the tab with one sample extension. It opens as a free account, the way most readers will first see it.
The dashed vertical lines are releases. Hover or tap the chart to see the date, the value and the version released that day.
What does a free account see, and what is Premium?
A free account sees the last 30 days of every metric. Longer periods are marked with a ★ and are Premium; clicking one on a free account shows an upgrade note and keeps the chart on 1M.
| Period | What the chart covers | Free account | Premium |
|---|---|---|---|
| 1M | Last 30 days | ✓ | ✓ |
| 3M | Last 3 months | — | ✓ |
| 6M | Last 6 months | — | ✓ |
| All | Everything recorded for the extension | — | ✓ |
The three tiles always summarise the last 30 days, on both plans. The period switch changes only the large chart. You need to be signed in to open an extension page at all; a free account is enough for everything in the 1M column.
Thirty days answers “what is happening now”. The longer periods answer “why”: in the sample above, the free view shows healthy growth after version 2.1.0, while 6M shows that the same extension lost users and rating after 2.0.0 in June and took two months to recover.
What does the user count mean?
It counts installations, not people who used the extension that day. Chrome’s own documentation says the users figure only captures installations and doesn’t show whether those users are active. So read it as reach, and look at the direction and the steps, not the exact number. The tile shows the change over 30 days as a percentage, green when it grew and red when it fell.
Popular extensions show a rounded user count, so their line moves in steps and can stay flat for weeks. A flat line means the count didn’t cross the next rounded step, not that nobody installed it. The tile then says “No change in 30 days” instead of 0%.
Growth right after a release usually means the update brought something people wanted, or the extension was featured. A drop right after a release is the first thing to explain.
How do you read the rating?
The rating is the average stars, shown to one decimal. Its chart always runs from 0 to 5, so a dip is drawn to scale. The tile shows the change in points, such as +0.1, not a percentage.
A rating with many reviews behind it used to move slowly. Since August 2026 the store’s rating focuses on more recent reviews, so a bad update shows up sooner, and even a 0.2 drop over a few weeks is a real signal. Here is the same sample on a Premium account, opened on the rating for 6 months:
The rating fell from 4.6 to 3.9 within a month of 2.0.0 and only started to recover after the 2.0.3 fix. When an extension’s rating drops after an update like this, the release lines tell you which version to look at, and the newest reviews on its store page usually say what broke.
How do you read the review count?
The review count is the total number of reviews, and the tile shows how many were added in 30 days, such as +18. A steady extension gains reviews at a steady pace, so the slope matters more than the total.
A sudden jump in reviews is the earliest sign that something changed. Check the rating for the same days: a jump with a falling rating means complaints, a jump with a steady rating usually means a growing audience or a request for reviews inside the extension.
Put the three lines side by side and most patterns read on their own:
| What you see | Users | Rating | Reviews | Likely meaning |
|---|---|---|---|---|
| Healthy growth | rising | steady | rising slowly | People install it and stay happy |
| Problem release | flat or falling | falling | jump | An update broke something or changed what users liked |
| Recovery | rising again | climbing back | back to the usual pace | A fix landed; check the release lines |
| Quiet or abandoned | flat | steady | almost none | No new users and no feedback; check the Versions tab for the last update |
How do you track an extension step by step?
- Open Find an extension and paste its name, its ID or its store link.
- Open the extension and go to the Trends tab.
- Read the three tiles for the last 30 days, then click the one you want to study.
- Keep Releases on to see which version came out before each change.
- To look further back, choose 3M, 6M or All.
When you compare several competitors, compare like with like. Look at the percentage change in users rather than the totals: +10% means very different absolute numbers for an extension with 5,000 users and one with 500,000, but both say the product is moving. Compare ratings only between extensions with plenty of reviews, because a 4.9 from a few dozen reviews can fall fast. Then line up the release dates: when a competitor ships a big update and its reviews jump, read the newest reviews on its store page to see what people praise or complain about.
To track a whole niche rather than one extension, first build the list of competitors with title keyword search, then open each one’s Trends tab. If you are judging whether to trust an extension at all, the verified publisher badge is the other signal worth checking. New to AppView? Start with what AppView is.
