Top Stock – Market Intelligence, Without the Noise
Top Stock turns the same feeds professional desks watch into one ranked, mobile-first view: live quotes, SEC filings, congressional disclosures and social sentiment, scored continuously and surfaced only when something moves.

Mission
Our mission with Top Stock was to give individual traders the kind of market awareness that used to require an institutional desk, without the noise that comes with it. We wanted an app that stays quiet most of the day, speaks up only when the data justifies it, and explains itself in a single screen.

Challenge
Retail trading apps tend to fail in one of two directions. They either bury the user in raw charts and filings, or they simplify so far that the recommendation cannot be trusted. Financial data also arrives from very different sources: real-time quote feeds, slow-moving SEC and congressional disclosures, and noisy social sentiment, each with its own shape, latency and reliability. The challenge was to fuse all of it into one score users would act on, fast enough to matter, and to present it without ever implying a guarantee.
Scope of Work
We designed and built the full mobile product for iOS and Android along with the marketing site at topstockalert.com. The scope covered brand identity, the alert and watchlist experience, the signal dashboard, congressional trade and filing feeds, sentiment scoring, push notification logic, and both App Store and Google Play launches.
Problems
Professional grade market data sat behind subscriptions retail traders could not justify. Free alternatives such as forums, social feeds and tip channels were unverifiable and often contradicted each other. The signals that mattered were already public in filings but buried and slow to surface. Existing apps pushed so many alerts that users muted them and missed the ones that counted.
Identity System
The identity had to read as credible without borrowing the cold, cluttered look of a trading terminal. We built a dark-first system on an obsidian and graphite base with a single high-contrast signal accent, and dedicated gain and loss colours used only for real movement, never decoratively. Outfit carries the headlines and JetBrains Mono the numbers, so prices and tickers stay aligned and scannable at a glance.
Logo
The mark reads as an upward move without becoming another generic arrow. It holds at notification size, in a home-screen icon and in a single colour on the store listings.
Research & Result
Testing with active retail traders showed the failure mode was alert fatigue rather than missing data. Users muted apps that pushed everything, then missed the signals they had installed the app for. That pushed us toward a quieter default: fewer notifications, each carrying its reason, with a ranked feed for anything below the notification threshold.
Landing Page
A single scroll: what the app watches, what a signal looks like, where the data comes from, and download. No pricing table, no countdown, no invented testimonials.
App Development Technology Stack
Top Stock is a native build on both platforms against one shared signal service, so a score computed once is the score every user sees. The marketing site runs separately so copy and store links can change without shipping an app update.

Data Sources Behind Every Signal
The score is only as good as what feeds it. Top Stock pulls live market quotes, SEC filings, congressional trading disclosures and social sentiment, each arriving on its own schedule and in its own shape. The integration layer normalises them, timestamps everything to a single clock, and degrades gracefully when one source is late rather than showing a stale number as if it were current.
Alerts That Earn the Interruption
Notification logic is the product. Every candidate alert is scored, ranked against everything else that moved, and held back unless it clears the bar. Users set the sensitivity once; the app decides what reaches the lock screen and what waits in the feed.
Available on iOS and Android
Both platforms shipped from one design system and one scoring service, so an alert looks and ranks identically wherever it lands.
The Journey Goes on
Top Stock is live on both stores and continues to expand its coverage of filings and disclosure sources. The roadmap stays deliberately narrow: better signals rather than more surface area.

The Equine Directory – Booking App for Equine Services
The Equine Directory connects horse owners with vetted equine professionals near them: farriers, stables and boarding facilities, equine veterinarians, and feed and supply sellers. It replaces the phone tree that finding a new farrier or a barn usually turns into with a searchable, filterable map and booking in two taps.
Every review is tied to a confirmed booking, so ratings reflect people who actually hired the provider. Search filters by service, distance, price and rating, availability shows live on the map, and messaging stays inside the app so a rider never has to hand out a personal number to get a quote. Provider profiles carry the detail owners actually ask for before they commit.

Task Haus – Home Services Marketplace
Task Haus is a two-sided marketplace for home repairs and maintenance. A homeowner posts the job with a budget, skilled workers bid on it, and the homeowner picks who to hire. Junk removal, painting a room, everyday repairs: the tasks that are too small for a contractor and too much for a Saturday.
Because the work is bid rather than quoted, homeowners see real competing prices instead of guessing at a market rate, and workers choose the jobs worth their time rather than paying for leads that go nowhere. The platform runs across mobile apps, a web app and an admin console, so a job can be posted from a phone and managed from a desk.
