01 — Portfolio
Six apps. Six industries. One team.
Every product on this page was designed, engineered, and delivered end to end by US APP Team — from an AI receptionist to a spaced-repetition study engine. Your app gets the same crew.
Anyone can show you mockups. We show you working products. Six real builds across six industries — the same playbook we'll run on yours.
Service business — AI receptionist
No Missed Call
An AI receptionist that rescues the calls service businesses miss — it texts callers back instantly, answers their questions, and books the job before a competitor picks up.
- AI call handling that steps in the moment the owner can't answer
- SMS follow-up flows that re-engage every missed caller automatically
- Booking integration that turns conversations into scheduled jobs
- Owner dashboard with every call, text, and booking in one place
Hospitality — Waitlist & reservations
TableCue
Restaurant waitlist and reservations without the paper list — walk-ins join a live queue and get pinged the moment their table is up.
- Walk-in queue with live wait-time estimates
- SMS “table's ready” pings that clear the host stand
- Host-stand iPad view for seating, notes, and no-shows
Fitness — Training & habits
FitStack
A workout builder for personal trainers — programs go out, check-ins come back, and clients keep their streaks alive.
- Program templates trainers reuse across their whole roster
- Client check-ins with habit streaks that keep people showing up
- Progress photos and history in a private timeline
Real estate — Open-house toolkit
OpenHouse+
Open-house check-in and follow-up for agents — visitors sign in on a kiosk, and every lead lands in the CRM before the door closes.
- Kiosk sign-in that replaces the clipboard at the door
- Automatic CRM sync so no visitor slips away
- Listing QR packs that hand every guest the full details
Retail — Loyalty & order-ahead
Brewly
Coffee-shop loyalty and order-ahead — a punch card that lives in the customer's pocket and a line that moves before they walk in.
- Punch-card wallet that rewards regulars automatically
- Curbside and counter pickup with live order status
- Seasonal menu drops pushed to every loyal customer
Education — Study & retention
StudyLoop
A spaced-repetition study app for students — flashcards resurface right before you'd forget them, tied to a real exam plan.
- Smart flashcards scheduled by a spaced-repetition engine
- Streaks and review goals that make studying a daily habit
- Exam countdown plans that pace the entire syllabus
