Atto — Ticket Drop Timer downloads
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.
Active users
All platforms, worldwide. Free with an account.
Stickiness (DAU / MAU)
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 Utilities 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 Atto — Ticket Drop Timer
A ticket drop is decided in milliseconds, not seconds.
The queue opens on the booking server's clock, not your phone's. The two are usually tens to hundreds of milliseconds apart, and that gap decides your place in line.
Atto reads the server's clock directly, and shows you how well it read it.
Measuring server time
An HTTP Date header only resolves to the second, so one read tells you ±500ms and no more. Atto probes at 137ms intervals so each request lands on a different phase inside the second. Once the offset narrows, it predicts when the server's second will roll over and aims at that edge. Twenty overlapping measurements fold the error down to the round trip.
The error bar stays visible
Instead of a label like "high accuracy" you get the measured figure: ±23ms. Sample count, rejected samples, best round trip, and how far this server runs from national standard time are all on screen.
Cached responses get dropped
When a CDN answers instead of the origin, the clock inside that response is frozen at the moment it was stored. Atto checks the Age and cache headers and keeps those responses out of the average.
Device drift correction
Your phone's oscillator runs seconds off per day. Atto measures the slope between syncs, extrapolates it to now, and re-syncs every two minutes while you wait.
Picture in Picture
Press Start and a Picture in Picture window floats above your other apps. Show a decreasing countdown or a corrected wall clock that advances toward your configured target, with three-digit milliseconds. Keep the timing in sight while using a booking app or webpage.
Haptics and sound
Taps begin at the lead time you set and end with one hard hit at zero. The whole pattern goes to Core Haptics up front rather than a timer, so zero does not move even if the screen stutters. Sound is optional and plays through the silent switch.
Practice mode
A recommended lead time is somebody else's number. Measure the gap between the buzz and your tap actually registering, then apply your own median.
Time sources
Over 300 sources across 14 regions, including Ticketmaster, AXS, StubHub, Interpark, e+, tixCraft and Damai, plus course registration sites and sneaker drops. Standard-time servers like NIST, NPL, PTB, NICT and KRISS are there too, and you can type any address yourself.
Free and paid
Everything that decides whether you get the ticket is free: full sync accuracy, drift correction, the on-screen countdown, haptics, every time source, practice mode.
One rewarded ad floats a single countdown in a PiP window. A one-time purchase removes ads and keeps PiP unlocked. It is not a subscription.
Reading a clock takes one HEAD request. Atto never asks for an account and takes no part in the booking itself.
