Hardcore Focus vs one sec (2026)
one sec adds a breathing pause before a distracting app. Hardcore Focus blocks the app and makes you argue with an on-device AI. Friction vs a wall.
Short answer: Pick one sec if you want a nudge, not a wall — a pause that a 2023 PNAS study (Grüning, Riedel, Lorenz-Spreen) found cut problematic app opens by about 57%. Pick Hardcore Focus if a pause is not enough and you need the app actually blocked during a focus session.
Quick comparison
| Hardcore Focus | one sec | |
|---|---|---|
| Mechanism | Screen Time block + Gatekeeper | Friction pause (Shortcuts + Screen Time) |
| Strictness | High | Low by design |
| Platforms | iPhone, Watch | iOS, Android, Mac, browser |
| Price (USD, Aug 2026) | $3.99/wk · $8.99/mo · $49.99/yr | Free (1 app) · Pro ~$19/yr |
Does friction work?
Yes, for a lot of people. The Max Planck / Heidelberg PNAS paper is why every listicle mentions one sec. A delay is enough when the habit is a twitch.
It is not enough when the habit is “I will wait out the animation and open Instagram anyway.” That is a block problem. Hardcore Focus Shield is the wall; Gatekeeper is what happens if you try to go around it mid-session.
Price
one sec is dramatically cheaper (~$19/year, free for one app). Hardcore Focus is a full focus app (timer, habits, Watch) behind a hard paywall. Do not buy Hardcore Focus to get a breathing animation.
Who should pick which
- I open apps on reflex and a pause would break it: one sec.
- I wait out pauses and need the app gone while I work: Hardcore Focus.
