How much time can you take back?

New to the idea? An hourly allowance is how Precursor works. Instead of one big daily budget, you get a few minutes each hour. Spend them and the app is blocked; the full allowance comes back when the hour turns. Because most scrolling happens in the evening, the allowance mostly trims your heaviest hours.

*assumes a 16 hour waking day, screen time that leans into the evening rather than spreading evenly, and that half of every blocked minute gets spent later in the day anyway. Your own numbers will vary; the short version of the math is below.

What fits in that time

Over a year, the hours above are enough for, with sources for the math:

If your numbers looked high: they are the average

Whatever the sliders said, you are almost certainly not an outlier. The scroll is built by professionals to be this good. That is exactly why an honest tool helps: 58% of American adults say they spend too much time on their phone (Gallup, 2022). Wanting some of it back is the majority position.

Notice the shape: around two hundred checks a day, most of them seconds long, and a few long evening sessions that carry most of the total. The total is built out of small moments rather than one big decision, which is why willpower alone is a rough tool for this and pacing works better.

Why the math uses an hourly limit

A daily limit is one big budget, usually spent by 9am, and then the day turns into a standoff with the Ignore Limit button (the long version of that story is in why daily limits fail). An hourly allowance paces the same habit instead: 5 minutes of TikTok per hour is still TikTok, a little, often. Spend it and the app is blocked; your time comes back when the hour turns. That is the whole mechanic of Precursor, and it is why the calculator asks for an allowance per hour rather than per day.

How the math works

Most screen time lands in the evening, with short checks through the rest of the day; that pattern shows up in every study that logs real phones (sources below). So the calculator spreads your daily minutes across the day the same way, caps every hour at your allowance, and assumes half of whatever gets blocked is spent later in the day anyway. The rest is yours, and the headline adds it up over a year. Arithmetic, not a promise; every number used is in the page source.

What this calculator does not claim

The math here is arithmetic, not a promise. A limit caps the time; it cannot make you spend the returned hours on novels, and some days you will spend every allowance of every hour, which is fine and still bounded. The day shape is a modeled typical pattern, not your actual hours; if your peak is at lunch instead of 9pm, the total comes out about the same. Minutes blocked in one app only become yours if they do not move to another app; Precursor limits the apps you pick, not your whole phone. The averages are the best-sourced figures we could find as of July 2026, and figures we could not trace to a primary source (the widely quoted "11 minute average TikTok session" survives only on aggregator sites) were left out on purpose. Your own Settings ▸ Screen Time number beats any average; use it.

FAQ

How much time does the average person spend on social media per day?

US adults average roughly 2 hours 16 minutes per day (GWI via DataReportal, 2025); the global average is about 2 hours 21 minutes. Per app in the US: about 52 minutes a day for TikTok users, 49 for YouTube, 34 for Instagram (eMarketer, 2025).

How long is an average doomscrolling session?

Objective logging studies find most phone pickups last under 30 seconds (55 percent in one PLOS ONE study that logged about 85 uses a day), while a small number of long sessions carries most of the total time. One 2025 US survey counted about 205 phone checks a day (Reviews.org). Short sessions, many times, plus a few long ones: that mix is the whole total.

How is "time back" calculated here?

Your daily minutes are spread across a 16 hour day the way screen time actually falls: mostly in the evening, a bump at lunch, short checks elsewhere. Every hour is capped at your allowance, and half of the blocked minutes are assumed to get spent later in the day anyway. What remains, added up over a year, is the headline number. Every input is in the page source; there is no hidden model.

Is there an iPhone app with limits that reset every hour?

Yes, Precursor (iPhone and iPad, iOS 17+). As of mid-2026 it is the only app built around hourly resetting allowances. Spend the allowance, the app is blocked, and your time comes back at the top of the hour.

Get Precursor

Precursor is in beta. Join at precursorlabs.studio; beta testers keep Precursor+ for life. Precursor is free for iPhone and iPad (iOS 17 or later) and is launching soon, with an Android version on the way.

The core mechanic costs nothing. Precursor+ adds up to 8 app groups, 30-minute reset windows, and time limits up to 30 minutes per hour ($4.99 a month, $49.99 a year, or $99.99 once). No account, ever. iOS hands me anonymous tokens, so I cannot see which apps you choose to limit.
