Doomscroll Impulse Redirector is a startup idea for people with ADHD and people trying to use their phone less. People with ADHD delete apps but still find somewhere to scroll (Reddit, email); blockers don't help because there's no willpower to stop in the moment. A thread in r/ADHD drew 60 upvotes and 39 comments between Sep 14, 2026 – Oct 14, 2026. People get by with one sec, Opal, and Screen Time, and that still leaves this job open. Hotness is 2.65, Simmering. Real but moderate pain. Price-sensitive audience. The thread drew 60 upvotes and 39 comments. Crowded with decent tools. A few weeks of work. A first version is a moderate amount of work, about 3–4 weeks, priced under $10 a month and charged as a free tier and a paid upgrade. The pain, the source, the alternatives, the scope notes, and the questions on this page are free to read and free to build from. The agent starter prompt is the paid part. The first slice is on the page. One credit unlocks the rest, to paste into a coding agent, download as Markdown, or send as a private link.

Market size · estimate
How big this could get
A bottom-up estimate for Doomscroll Impulse Redirector: real customer counts × a realistic price. Not a forecast.
$234M a year
7.8M adults · 50% of US adults with a current ADHD diagnosis
$60M a year
2M adults · app-store reach
$600K a year
20,000 adults · 1% of the reachable segment in three years
What that means
20,000 adults at $2.50/mo = $600K ARR
Medium confidenceHow we estimated this
- Base: 15,500,000 US adults with a current ADHD diagnosis.
- Has the problem: 50% (assume half struggle with phone scrolling).
- Revenue per adult: $30 per year ($2.50/mo).
- Reachable: 25% (app-store reach).
- Three-year capture: 1% of the reachable segment.
TAM = customers with the problem × revenue per customer. SAM = the part an early product can reach. SOM = a conservative three-year share of SAM. Bars use a log scale. Shares marked “assume” are our judgment, not measured.

Is this idea already taken?
People already use one sec, Opal, Screen Time. Those options do not do the job in the solution above. The idea is free to build. Nothing here is an exclusive claim.
How hard is a first version?
Moderate. A tight MVP is about 3 weeks (3–4 weeks), assuming the regulated or partner-gated parts are stubbed. The paid prompt turns that into tasks.
Who would pay, and how?
The audience is people with ADHD and people trying to use their phone less. Charge a free tier and a paid upgrade, and test a price under $10 a month. Willingness to pay is one input to Hotness, not a promise that someone will buy.
Can I use the evidence?
Yes. Build the product. The thread title is a short excerpt with a link, not a quote we are putting in someone's mouth. Exact post dates and verbatim lines are added only after a manual check. Ideas are suggestions, not medical, legal, or financial advice.
