One Sec pricing,
individual, family, and lifetime options

One Sec runs a freemium model with individual and family tracks, each offering monthly, annual, and lifetime options. The free tier is real but limited to one app or website. Pro removes that cap, and a separate Family plan covers more than one person under a single subscription.

This page focuses specifically on cost. For the full feature comparison against Fella, see Fella vs One Sec. What follows is a plain breakdown of what you pay and what you get at each tier.

These are US App Store canonical prices for Pro. One Sec's EUR FAQ values are regional only, not the US canonical figures, and a separate team multi-seat rate starts from 83 cents per user monthly, billed annually via web checkout.

One Sec's free tier isn't a stripped trial, it's a functioning single-app version. You get the core Breathing Exercise and Re-Intervention features on one app or website of your choice, with no ads interrupting the experience.

The limitation is scope: one app only. If the habit you're trying to interrupt is spread across two or three apps, the free tier can't cover all of them simultaneously, which is the main reason people upgrade.

Strict blocks and Cheat Locks are Pro features. The free tier's pause-based intervention doesn't include the harder Strict blocking mode or its 5 Cheat Locks, both exclusive to the paid tiers.

Coverage beyond one app requires Pro. Every app or website beyond the free tier's single slot needs a paid subscription.

Strict blocks with Cheat Locks are Pro-only. This optional stricter mode, complete Manual, Recurring, Focus-Filter, and wake-up blocks, sits behind the paid tiers, not the free version.

Time Tracking is specifically noted as a Pro feature. While diagrams, time-saved comparisons, and a 24-hour insight are part of the broader analytics set, Time Tracking itself is called out as Pro-exclusive in current documentation.

Monthly costs more over a year. At $2.99 a month, a full year runs about $35.88, considerably more than the $19.99 annual plan for the same individual coverage.

Annual is the clear value tier for individuals. $19.99 a year works out to roughly $1.67 a month, the cheapest ongoing option short of a one-time lifetime purchase.

Lifetime breaks even in about five years. At $99.99, the individual lifetime plan costs roughly five years of the annual plan, a reasonable bet if you're confident you'll use One Sec long-term.

Family plans carry a modest premium over individual pricing. Family Annual at $29.99 is $10 more than individual Pro Annual, and Family Lifetime at $149 is about $49 more than individual Lifetime, the cost of covering more than one person.

The free tier suits someone testing whether a pause-based intervention works for one specific habit. If a single app is the main source of distraction, the free tier alone may be enough.

Individual Annual is the practical choice for most solo users ready to commit. At roughly $1.67 a month, it's the lowest ongoing cost short of a lifetime purchase.

Family plans suit households wanting to cover more than one person under one subscription. The modest premium over individual pricing is worth it once you're paying for more than one account anyway.

One Sec is considerably cheaper at every tier, and it offers a free version, a trial, and a lifetime purchase Fella doesn't have. On price and flexibility alone, One Sec is the more accessible option.

Fella's higher price buys a different mechanism, not more configuration. One Sec's pause can still be clicked through; Fella blocks the app outright, with one 5-minute emergency unlock per session, the same on day one as after a year.

The choice depends on whether a pause or a block is what you actually need. If a moment of friction is usually enough, One Sec's lower price makes sense. If you've noticed yourself breathing through the pause anyway, that's a different problem. See how Fella works or Fella's current pricing for specifics.
