Two things jump out of that table. The tools that cover all three behaviors are mostly the ones built around detection or around logging, not around treatment content. And the only entry with a real evidence base behind it, rather than vendor claims, is the free one.

What separates a good BFRB tool from a bad one

Vendor pages all claim high success rates. HabitAware says 90% of Keen2 users show improvement, Hands Off claims a 70 to 90% reduction in episodes in the first week, TrichStop says 90% of people who finish its modules improve. None of those are independent findings, and you should treat them the way you'd treat any number a company publishes about itself.

The research that isn't vendor-produced points at five things worth checking instead.

1. Does it teach a technique, or only count?

A counter that tracks your streak is not one of those. Tracking is the input to a method, not the method.

2. Does the technique match your behavior?

This is the finding that never makes it into an app roundup, and it matters most if you have more than one BFRB. The same review found decoupling and decoupling in-sensu "especially effective for hair-pulling and nail-biting", while decoupling was less effective for skin picking. Habit reversal training performed consistently across all of them. So a tool built entirely around one competing-response technique may serve one of your behaviors well and the other poorly.

3. Will you still open it in three weeks?

4. Does it cover the behavior you have, not the behavior it markets?

Half the products in this space were built for one BFRB and later described as covering the rest. Read the actual feature list. A hair-pulling app that lets you type "picking" into a notes field is not covering skin picking.

5. Where does the camera or the data go?

The detection tools work by watching you. SmartBehavior and Hands Off both process on-device and say nothing is recorded or transmitted, which is the right answer, but it's worth confirming for yourself before you leave a webcam running during your workday.

The tools, briefly

Each of these gets a proper head-to-head on the condition pages. Skin picking is covered in the skin picking app comparison, hair pulling in the hair pulling app comparison, and nail biting in the nail biting app comparison. What follows is the umbrella view.

Free from BFRB is a free psychoeducational site and PDF manual from University Medical Center Hamburg-Eppendorf, teaching self-guided HRT, decoupling, decoupling in-sensu and habit replacement. It was the most studied resource in the 2025 review, and around 70% of participants across those trials reported positive effects. It has no app, no reminders, no tracking and no community. It is also the closest thing to a free, evidence-backed starting point that exists, and most people shopping for a BFRB app have never heard of it. Start here, then decide what you still need.

HabitAware Keen2 is a bracelet rather than an app. It detects the gesture and buzzes, which is the one thing a log can't do: reach the behavior you're not aware of yet. It covers picking, pulling and biting, and it's the tool therapists in this space most often name. The trade-offs are the $169 up-front cost, the training period before detection gets reliable, and the false buzzes you'll get from ordinary gestures. KeenLite runs the same idea on an Apple Watch you may already own, in one-hour sessions rather than continuously.

SmartBehavior and Hands Off attack the same problem with cameras instead of a wrist sensor. SmartBehavior uses the phone camera on-device; Hands Off runs on a desktop and interrupts with a pop-up, covering five behaviors including eyebrow and eyelash pulling. Hands Off is transparent about price (€2.99 a month after a 3-day trial). SmartBehavior's price we could not confirm from its own site or store listing, so treat it as a paid subscription and check before you commit.

SkinPick and TrichStop are not really apps, they're online therapy programs with trackers attached, one for picking and one for pulling. Both run $65 to $90 per week, billed every four weeks, with no free tier. That's a therapy budget rather than an app budget, and it can be the right call if there's no BFRB specialist within driving distance of you. Neither covers nail biting, and neither covers the other one's behavior.

BFRB Buddy logs daily mood and emotion against your behaviors and shows you a monthly calendar. It's Android, it's simple, and it stops there. If all you want is a record you can bring to an appointment, it does that.

SkinAware is ours. It handles all three behaviors, and it's the one place here where you can have more than one selected at once and have the logging flow adapt (a hair-count step appears when hair pulling is one of your behaviors, and doesn't when it isn't). Alongside logging there's an HRT course in short modules, a daily check-in, progress and goal tracking, a private photo timeline, data export for a clinician, accountability friends and a moderated community. The core is free; the full course and the deeper features sit behind a subscription. Where it's weaker: it doesn't detect anything. If your behavior is fully automatic and you only notice afterwards, a bracelet or a camera reaches a moment we can't.

If you have more than one BFRB

This is the case the rest of the internet handles badly, and it's more common than the marketing suggests.

Hair pullers with co-occurring picking were also more likely to have depression. The authors' conclusion was that assessing for multiple BFRBs matters clinically.

Practically, that changes three things about how you shop.

First, running two single-behavior apps means two logs, two sets of reminders, and two partial pictures of what is very likely one underlying pattern. Most people abandon the second one within a month. If your behaviors share triggers, and they usually do, you want them in one timeline where you can see that Tuesday evenings set off both.

Second, the technique split matters more for you than for anyone else. If you pull and pick, the decoupling material that helps the pulling may do less for the picking, while habit reversal training tends to hold up across both. That's an argument for a tool built on HRT as the spine, with other techniques layered on.

Third, a detection device only detects what it's set to detect. Keen2 and the camera tools let you select the behavior; if you switch between behaviors through the day, you'll be switching modes too, or missing one.

If you got here because you'd just learned the acronym and you're still working out which behavior you actually have, the foundational guides are a better next stop than any of this: skin picking disorder and trichotillomania.
