NagTheBank.com

Fee Fight Autopilot

A bank-fee watchdog for overdraft fees, mysterious charges, ATM fees, rate increases, and recurring billing errors. Users connect or upload transaction data, choose their complaint style, and let the app periodically flag suspicious charges and prepare targeted messages to banks or merchants. The differentiator is a playful “nag engine” that remembers unresolved cases and follows up at randomized, human-looking intervals until there is an answer or the user closes the case.

Subscription Grievance Scheduler

A “subscription regret” agent that watches a user’s inbox for renewal notices, price hikes, failed cancellation attempts, and free-trial endings. On a user-defined cadence, it drafts and sends polite-but-firm complaints, refund requests, retention-offer requests, or cancellation follow-ups to the right company. Start with email forwarding plus AI-generated drafts and an approval button; later add a simple timeline showing money recovered.

Order Complaint Escalator

A service for shoppers who receive damaged, late, misleading, or incomplete online orders. Users forward an order confirmation and upload a photo; the app identifies the merchant, summarizes the issue, cites the relevant order details, and schedules escalating messages: first a friendly support request, then a firmer follow-up, then a card-dispute-ready evidence packet if ignored. It turns the annoying “I’ll complain tomorrow” task into an automated routine.

Mat Boss

A lightweight tournament operations tool for small karate events that handles divisions, bracket generation, mat schedules, volunteer assignments, live result entry, and automatically shareable result pages. It is designed for the often-chaotic local tournaments that are too small for expensive event platforms but too complex for spreadsheets.

Dojo Passport

A dojo “skills passport” that lets karate students log techniques, kata, sparring rounds, injuries, and belt-test requirements across gyms or while traveling. Instructors get a simple rubric-based review flow and can issue verified progress badges without replacing their existing membership software.

Kata Mirror

A video-based kata practice coach: students upload short clips, choose a kata, and receive structured self-review prompts for stance depth, timing, balance, and sequence accuracy. Rather than pretending to replace a sensei, it creates practice plans and highlights clips/questions the student should bring to their instructor.

PunchlineAnalytics.com

Round Replay

A sparring debrief tool that turns quick post-round voice notes into structured learning. Fighters record what landed, what they kept getting caught by, and one adjustment for next time; the SaaS tags recurring patterns over weeks and produces a personal “fight tendency” report. Dojos could use it for controlled tournament preparation without needing expensive video-analysis systems.

BeltAndBrag.com

Belt Journey

A belt-test operations platform for small martial-arts schools. It manages requirement checklists, attendance thresholds, payment eligibility, parent notifications, examiner scoring, and printable certificates—while giving each student a clear path from their current belt to the next. Its differentiator is a visual ‘belt journey’ that makes progress motivating rather than administrative.

KataLater.com

Kata Recall

A dojo “technique decay” tracker for students and instructors. Members log the kata, drills, and combinations they practiced; the app uses spaced repetition to tell them what is most likely to be rusty before grading day. Instructors get a heatmap of class-wide weak points and can generate a warm-up plan around them.

PuttIDunn.com

Putter Passport

A SaaS tool for golf shops, fitters, and private sellers that creates a "putter provenance passport" for every club. Each passport records serial numbers, specifications, loft/lie adjustments, restoration history, ownership chain, photos, authenticity checks, and value updates. The result is a shareable, trustworthy listing page that helps premium putters sell faster and reduces disputes around modified or counterfeit clubs.

ForeSaleByOwner.com

UnderPar Finder

A market-monitoring and deal-alert platform built for putter flippers and collectors. Users define saved searches such as "Scotty Newport under $250," "left-handed milled putters," or "rare Ping Anser stamps," and receive alerts when listings appear under estimated market value. A built-in profit calculator accounts for shipping, marketplace fees, restoration costs, and likely resale price, turning niche golf knowledge into repeatable buying decisions.

PuttPriceIsRight.com

Putter Portfolio

A collector-focused pricing intelligence platform for putters: users upload photos, enter model details, and track estimated resale value using comparable listings from marketplaces, auction results, and sold inventory. It could flag rare stamps, original shafts/grips, condition issues, counterfeits, and price trends by maker, model, finish, and year. Revenue could come from premium valuation reports, dealer accounts, and API access for golf shops.
