Worldwide, per day, and installs to date. The band is open; the exact number is free with an account.
How this is calculated
Apple publishes no download counts. App Store downloads come from chart positions and daily rating growth per country, calibrated on Google Play install counts; lifetime installs from ratings worldwide × installs per rating. Confidence is the chance the real number is within half to double ours.

how many monthly users open it on a given day
How this is calculated
Monthly users come from lifetime installs across every store, fitted on monthly active user figures companies publish; daily users = monthly × the typical daily/monthly ratio for the category. Confidence is the chance the real number is within half to double ours.

Review momentum
20/100
faster than 0% of Books apps
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.
About Trace: Fanfiction Tracker
The app that brings you all the features you wish AO3 had!
Keep reading on AO3 and don't trust your AO3 login details to a third party app. Trace adds a Safari extension that adds your reading memory right on the screen without asking for your AO3 login, and gives you a beautiful library to organise your fanfiction, see your reading stats, and create customisable collections for yourself or to share.
SEE WHAT YOU'VE ALREADY READ
Don't you hate reading what you thought was a new story only to realise part way through that you read it years ago? Trace marks the fics you've already read, finished, paused or dropped, right on the browser list, with your chapter. And as you browse you can save new stories with a tap so that it's never forgotten.
AUTOMATIC TRACKING
Open a fic on AO3 or FFN and Trace automatically tracks it to your library. You never need to save it to an open tab again because it's right there in your Trace library waiting to be opened.
A PERSONALISED LIBRARY
Every fic you've opened in one place: reading, saved, caught up, paused, finished, re-read, or dropped. Filter it with all of AO3 and FFN's filters, search title, description, tags, and notes, and see what you've read every day in the recent history view.
Rate a fic, leave yourself a note, add private tags.
CLOSE THOSE OPEN TABS
New feature: Import all your open AO3 and FanFiction.net tabs in one tap. Trace keeps the stories, with the chapter you're on, so you can close the tabs.
NOTIFICATIONS
Get new chapters from your AO3 subscriptions as notifications on your iPhone, and see what's new in one place. You set it up once and then every update goes straight to your library ready for you to open. Titles stay off your Lock Screen unless you turn them on. FanFiction.net isn't supported yet. Works with Gmail, Outlook, and iCloud emails.
COLLECTIONS
Gather the fics you love, rank them, group them, add notes and guides, and send a link.
STATS AND RECAP
See how many words you read each month, the spread of your reading each year, the tags you love and the fandoms you read the most.
ON YOUR HOME SCREEN
Add the widget to see what you're reading and jump back in.
FREE OR UNLIMITED
Trace is completely free for up to 100 stories with no ads and no time limit, then a small subscription ($2.99 a month or $24.99 a year) gives you unlimited space and supports the project if you think it's worth it. All features are included in free except for advanced stats since fewer than 100 stories can't make use of them.
YOU STILL READ ON AO3 AND FFN
You always read on AO3 or FanFiction.net, so authors keep their hits and kudos. The Safari extension only asks for access to AO3 and FanFiction.net, and it stays off their sign-in pages. I'll never ask for your AO3 or FanFiction.net password. I don't sell your reading or show you ads.
