Shimmer — human 1:1 weekly ADHD coaching (US)

What it is

Shimmer is the most advanced 1:1 human ADHD coaching platform on the English-speaking market in 2026. Founded in San Francisco in 2021 by Chris Wang (CEO, late-diagnosed ADHD), it combines:

1. Weekly 1:1 video session (45 min) with an ICF-certified coach trained internally by Shimmer on ADHD.
2. Daily body doubling (unlimited co-working video sessions, 7 days a week).
3. Themed workshops on a regular basis (emotional regulation, sleep, routines, executive function).
4. Video library + in-app tracking tools.

The positioning is clear: not a self-guided app (like Inflow) but a serious substitute for a traditional private coach, with the infrastructure of a tech platform.

Pricing

• Full price: $230/month (€215 / ~£183).
• Recurring promo: ~$172/month (-25%, almost always offered at signup).
• Annual: ~$2,000 to $2,760/year depending on plan.
• No real free trial: credit card required at coach matching; refund guarantee on first session if serious mismatch.

For context:

• US certified private ADHD coach: $150-300/weekly session → $600-1,200/month.
• ICF/ADDCA-certified private ADHD coach in France: €80-120/session → €320-480/month.
• Shimmer costs roughly the price of a certified French private coaching, plus body doubling and workshops, but in English and with no French-speaking anchor.

What works

The real human coach. Not a chatbot, not a pre-recorded programme: a person, a match, a relationship of 3-12 months. That’s Shimmer’s core differentiator vs every self-guided app.

Serious certification. Shimmer coaches must be ICF-certified ^[3] (the only internationally recognised coaching credential) and pass Shimmer’s in-house ADHD training. A real gap vs the French market where the word “coach” is not legally protected.

Daily body doubling included. You can join co-working video sessions every day, several times a day, at no extra cost. Between two coaching sessions, it maintains accountability.

Grounded in the founder’s lived experience. Chris Wang speaks publicly about his late diagnosis, and that shapes the product. Less aggressive “hack your brain” marketing, more respect for lived ADHD experience.

Open to self-identified folks. Shimmer accepts people not yet officially diagnosed (waiting for an appointment, mid-process). Honest and useful given diagnosis waiting times.

User satisfaction. 4.8 rating on stores, with detailed qualitative feedback (not just empty stars).

What raises questions

The price. $172-230/month is a serious financial commitment. Frame it mentally as “therapy” or “pro coach”, not as “productivity app”. At that price, a French speaker could see a CBT-ADHD psychologist in private practice with better cultural fit.

English is mandatory. Coaches are US/UK English-speakers. Workshops, the app, everything is in English. A non-bilingual person loses 80% of the value.

No EU / GDPR anchor. Shimmer is US-based. Your health data (what you tell your coach, your notes, your progress) is hosted outside the EU. Not necessarily a dealbreaker, but worth knowing before committing.

Imperfect coach matching. Like any therapeutic relationship, fit matters. Some users report having to change coach 1-2 times before finding the right one. Shimmer makes switching easy but it’s still emotional friction.

Not medical care. Shimmer says it clearly: it’s not therapy, it’s not diagnosis, it’s not a psychiatrist replacement. If you have a severe comorbidity (resistant depression, disabling anxiety, PTSD), you need something else in parallel.

Evidence level. Shimmer has not published a peer-reviewed RCT validating its own efficacy. It’s coaching, not therapy — so outside the regulated medical field. Consider it serious support, not validated care.

For whom, for what

Good fit if you are:

• An English-comfortable ADHD adult with a comfortable budget ($1,500-3,000/year sustainable).
• You’ve tried on your own (apps, books, Reddit) and you need someone who knows you.
• You have a concrete project (launching an activity, surviving a master’s, stabilising a post-burnout routine).
• You’re waiting on diagnosis or diagnosed but without access to an ADHD CBT psychologist.

Avoid if you are:

• Not a comfortable English speaker (really — this won’t half-work).
• On a budget below $100/month for this line item.
• In acute crisis (→ see a psychiatrist urgently, not a coach).
• Uncomfortable with non-EU data hosting.

Alternatives

• Inflow: ~€13/month, CBT modules + group coaching. Less personalised, 10-15× cheaper. Good budget substitute.
• Certified French-speaking private ADHD coach (ICF/ADDCA/PAAC): €80-150/session. Less infrastructure (no included body doubling), but French-speaking and GDPR-compliant.
• CBT psychologist in private practice (France): €60-100/session, better reimbursed (Mon Soutien Psy since 2024). Therapy > coaching if clinical need.
• Focusmate: $10/month, body doubling only. Useful complement.

Verdict

Shimmer is the benchmark for tech-enabled ADHD coaching in 2026, provided you’re an English speaker and can handle the price. The infrastructure quality (matching, app, included body doubling) is real, the late-diagnosed CEO gives the product legitimacy, and coaches are properly certified — which remains rare.

The French-speaking gap is glaring. No equivalent platform exists in French in 2026. One of the most obvious product opportunities on the French market.

Heads up

• Not a diagnosis, not therapy, not a doctor. Shimmer is a coaching service (support), not medical care.
• If you’re in crisis (suicidal thoughts, major depression), call 988 (US Suicide & Crisis Lifeline), 116 123 (UK Samaritans) or 3114 (France) — or contact your GP first.
• Data hosted in the US: read the privacy policy if you’ll discuss sensitive topics (sexual orientation, substance use, family conflict).
• Coach matching may take 1-2 tries. Don’t judge the platform on a single session.
