App Portfolio

Built for the systems
that fail people
when it matters most.

Amethyst Reign is a solo-founded app portfolio building tools for the problems everyone has -- but nobody solves. Each app starts from lived experience with a broken system.

The Portfolio

Three apps.
One mission.

Every Amethyst Reign app addresses a systemic gap -- a moment where existing tools fail the people who need them most.

🗹
ReignVault
Find what you hid from yourself.
Live Alpha

Photograph anything you put somewhere safe. AI describes the item and its location in detail. Find it later by describing what you need -- in plain language, even offline. Built in six hours to solve a real personal problem. Now being used by therapists, counselors, and their clients.

01
Snap it
Take a photo of the item in its location. Give it a name.
02
AI describes it
Claude generates a rich, searchable description -- item, location, context.
03
Find it later
Search in plain language. "The charger." "My passport." "The thing in the kitchen." Works offline.

🌧 V1 Prototype
ReignItIn
Reign it in.

Real-time crisis navigation for the hours when your providers are unreachable and you're not okay -- but it's not 911, and it's not 988. Verified warm lines, personalized crisis plan, panic kit, wearable early warning.

The gap
Your therapist has office hours. Your psychiatrist has a 48-hour response policy. The crisis doesn't check their calendar.

ReignItIn supports users in the gap between provider availability and emergency escalation. It is not a replacement for emergency services or clinical care.

😵 Coming Soon
RingReign
Take back your phone.

Call blocking + crowdsourced spam reporting + one-tap FTC/FCC filing + a legal pipeline connecting users to TCPA lawyers and corporate legal benefit programs.

The gap
Everyone gets spam calls. Nobody knows they can sue. RingReign blocks the calls, reports them, and connects users to legal recourse.

Why we build

Infrastructure for
broken moments.

The best tools are built by people who needed them and couldn't find them. Every app in this portfolio started with that moment.

🧠
Neurodivergent-first

Built by someone with ADHD, for the cognitive reality of people who process differently. Low friction, high adaptability, zero judgment.

⚡
Works when you can't

Every product is designed for the moment of lowest executive function -- when the system has already failed you once and you need something that just works.

🔓
Access is non-negotiable

Crisis tools will never be paywalled. The people who need these products most are often least able to pay for them. Revenue comes from providers and institutions -- not people in crisis.

The Founder
Robin Deans with Bert the dog and Ernie the cat
Robin with Bert & Ernie — the original users
"My father asked: what if someone without your intellect was suffering this way -- what would happen to them? That question is the mission."
Robin Deans

Robin is a neurodivergent builder and crisis survivor who builds tools to solve problems she has lived personally. She built ReignVault in six hours because she was frustrated with losing things. She built ReignItIn during a mental health crisis because the system had no roadmap for her.

She moves quickly from firsthand insight to usable product -- using AI-native development to compress months of build time into days. She is the user. Every time.
