← All ideas IDEA-103 7.2 us health-companion developed

Three tasks. One trusted human. That's it. The ADHD app that doesn't punish you for using it on a bad day.

Problem

Adult-ADHD users cycle through 3-5 productivity apps (Todoist, Notion, Tiimo, Habitica) and abandon each within weeks because the maintenance cost of the system exceeds their executive-function budget. They mute alarms reflexively, can't navigate multi-screen setup, and shame-loop blocks task initiation. The 'body doubling' workaround — texting a roommate to ping if a task stalls — works, but no app makes accountability-pairing first-class without turning into public gamification.

Audience

US adults with ADHD 28-45, employed but battling time blindness daily, who have already tried Todoist + Notion + Tiimo + Habitica + paper, are self-aware enough to want a tool that 'works on the worst day, not the best day', and have at least one trusted person (partner / roommate / parent) for accountability

What we ship

**Core features (MVP)**

**3-task daily cap (hard limit)**: user can add only 3 tasks per day. Backlog hidden by default ("show backlog" available, but "promote to today" disabled if already 3).
**Context-aware nudges (rule-based)**: GPS-based — "you're home, morning, 'clean bathroom' is waiting" (right place / time, no manual setup). Nudges = text + optional user-recorded voice phrase ("hey, bathroom waits, no rush") — recorded once.
**One-supporter accountability**: invite ONE person via SMS link. Supporter sees ONLY stalled tasks (not content, only flag "stalled 3 days"). Can tap "send pep" → user receives "Maya is rooting for you on the bathroom". No public gamification.
**Bad-day mode**: one big button "today's a bad day" → tasks hide for 24h, supporter auto-notified "low capacity, no asks". Anti-shame design.
**Dopamine micro-reward**: on complete — short visual reward (confetti + user-recorded positive voice phrase). NO XP bars, NO streaks (anti-shame).
**Anti-features**: NO XP, NO streaks, NO public leaderboards, NO AI-generated nudges (sound fake to ADHD audience), NO "you're not productive enough" notifications.

**Primary user flow**

1. Signup (Apple Sign-in / email). 30-second onboarding: "how many tasks in your worst day?" → default 3.

2. First use: "record 3 pep phrases for yourself" (10 sec, voice). These play during nudges.

3. Optional: "invite one supporter via SMS" (skippable).

4. Daily use: open, see 3 tasks, complete → confetti. Stuck → swipe "needs body double" → supporter ping.

5. Free: 3 tasks/day, 1 supporter, basic context-nudges. Pro $4.99/mo: unlimited supporter notes, voice-pep library, calendar integration, custom bad-day templates.

**What it looks like**

**Landing**: "An ADHD app that works on bad days." hero. Quote: "Spent 3 weeks building my perfect system, used it for 2 days." vs our anti-pitch.
**Main app screen**: 3 task cards. Below them one button "today's a bad day".
**Supporter view**: minimal screen with 1-2 stalled tasks + "send pep" button. No content visibility.

**MVP build plan (9 days)**

Day 1-2: Postgres schema (tasks, supporters, nudge_records), FastAPI, Stripe.
Day 3-4: PWA UI with 3-task cap (hard limit in UI and API), dark mode, voice recording for pep phrases.
Day 5-6: Twilio SMS supporter invites + minimal supporter web view, geofence-based nudges (Web Geolocation API).
Day 7-8: Calendar read-only integration, bad-day mode flow, paywall.
Day 9: landing ("works on bad days"), deploy, launch on r/ADHD.

Reasoning

Triple pain from 3 SIGs: SIG-app-overload-paralysis (3-task cap + no backlog — core wedge), SIG-body-doubling (one-supporter accountability — specific ADHD mechanic), SIG-alarm-mute-loop (context-rule-based nudges without manual setup — anti-mute pattern). Existing leaders: Tiimo ($8/mo, decent but 30+ field onboarding), Inflow ($30/mo — too expensive, frames as coaching = quasi-medical), Habitica (gamification = public shame). Nobody does one-supporter without social gamification. Regulatory-safe: we do NOT diagnose ADHD, do NOT prescribe coping strategies (just infrastructure for self-help), do NOT sell as therapy. Lesson from IDEA-047: AI deliberately disabled in MVP — user records own voice phrases, nudges are rule-based from GPS+time, no LLM-generated "therapeutic" speech. Clean differentiator: 3-task cap (hard) + one-supporter (privacy-first) + bad-day mode (anti-shame) — combination that doesn't exist on the market.

Quick competitive read

**Tiimo** — visual scheduler for ADHD, $8/mo, but onboarding overload, no supporter mechanic.
**Inflow** — daily check-ins + AI coaching, $30/mo, frames as therapy-adjacent — exactly what IDEA-047 lesson teaches us to avoid.
**Habitica** — gamification + public leaderboards vs our anti-gamification stance.
**Sunsama** — daily planning for productivity pros, not ADHD-specific, $20/mo.
**Routinery / Structured / Saner.AI** — all have some ADHD features but no one-supporter accountability + 3-task hard cap + bad-day mode.
**White space**: medium (ADHD product market is saturated in general, but the specific combo of 3-cap + one-supporter + anti-gamification doesn't exist). Score hint: competitive_pressure 4-5.

Initial pricing hypothesis

Free: 3 tasks/day + 1 supporter + basic nudges. Pro: $4.99/mo or $39/yr — unlimited voice-pep library, calendar overlay, custom bad-day templates, history beyond 30 days. Price deliberately low (vs Inflow $30, Tiimo $8) — wedge on accessibility. Goal: high retention (LTV > CAC), not premium ARPU.

Distribution hypothesis

1) **r/ADHD (1.5M+) + r/ADHD_Programmers (300K+) + r/adhdwomen (1M+)** — solo-dev "Built this after deleting 7 productivity apps. Three tasks. One human. That's it." Authenticity-driven.

2) **TikTok #adhdtok (100M+ views)** — short demos "3 tasks. One human. Watch me have a bad day with this app." High viral potential.

3) **ADHD-aware creator newsletters** — How To ADHD (Jessica McCabe), Hacking Your ADHD (William Curb), Black Girl, Lost Keys — outreach with personal "as an ADHD founder" angle, free Pro affiliate at 30% per-conversion.

Regulatory

clean

Cleanest IDEA in this batch from a regulatory standpoint. AI is deliberately disabled in MVP (no LLM-generated nudges, no AI coaching). Voice phrases are user-recorded by self for self. Nudges are rule-based (GPS + time + calendar event awareness), not predictive ML. The product positions explicitly as "infrastructure for self-help", NOT therapy or medical claim. The IDEA-047 lesson is well-applied: deliberate AI absence eliminates SaMD-creep risk entirely. The supporter mechanism (one-trusted-human SMS pings) is essentially a structured texting interface — no clinical context, no PHI, no health-data classification trigger. The "bad-day mode" is anti-shame UX, not therapy. No D-001 (HIPAA) — task data is productivity data, not PHI. No D-006 (SaMD) — no diagnostic or treatment claim. No D-011 (COPPA) — audience is adults 28-45. SB-004 (EU AI Act high-risk) does NOT apply: US-only target, and even on EU expansion, productivity tools are NOT in the high-risk Annex III list (which covers hiring, credit, education access, law enforcement). Twilio SMS supporter pings: standard TCPA compliance — explicit opt-in by supporter required when invited by SMS link; record consent timestamp. US regional advisory: WA MHMDA likely does NOT apply since data is task/productivity data, not "consumer health data" under the Act's definition (mental health condition information IS covered, but the product avoids any framing of ADHD as a diagnosis or treatment target — task data alone is not consumer health data). Defensive recommendation: still keep ADHD-mention as user-stated category not a verified diagnosis. TCPA: get explicit opt-in for SMS pings (Twilio standard). Consider adding "trusted-supporter age confirmation 18+" since supporter receives task notifications about another adult. BUILD RECOMMENDED with light guardrails: (1) onboarding disclaimer "this app is a productivity tool, not ADHD therapy or treatment — see a clinician for diagnosis/treatment"; (2) keep 'ADHD' framing as user-self-identified category, never as a clinical claim; (3) TCPA-compliant SMS opt-in for supporters (logged consent record); (4) supporter age-verification 18+ at invite acceptance; (5) maintain deliberate-no-AI for v1 (defer any LLM-generated coaching to a separate post-MVP review).
