Memberchip vs MathBlocker

Memberchip is operating infrastructure for owner-operated recurring-activity businesses: clubs, studios, academies, schools, and coaches that sell memberships, passes, subscriptions, and recurring sessions. Instead of stitching together booking tools, payment links, spreadsheets, and manual follow-up, owners can manage payments, access, attendance, schedules, and client activity in one system. For owners and managers: - Sell memberships, passes, subscriptions, or single-session access through shareable links and QR codes - Accept secure payments and keep attendance connected to each client - Create groups, schedules, events, classes, and recurring sessions - Let clients book, check in, and cancel attendance independently - Scan membership QR codes to verify visits when staff assist clients - Track attendance, active clients, repeat visits, and revenue signals - Manage multiple clubs or locations from one account For clients: - Buy memberships or subscriptions from a club link or QR code - View upcoming events and class schedules - Book ahead, check in independently, and cancel if needed - Access active memberships and attendance history - Use one app across multiple clubs and studios Memberchip is the live operating layer for payments, access, attendance, and recurring activity today, with growth and retention workflows being built on top.

MathBlocker puts a math problem between you and the apps you open too much. You pick the apps you want blocked. When you try to open one after your time's up, a math question shows up instead. You answer it, you get a few minutes back. You don't, the app stays closed. The questions are real. They come from the same problem sets people use to study for the SAT, ACT, AMC, and AIME. You can set the difficulty. Easy questions if you just want a speed bump. Harder ones if you actually want to stop scrolling. Features - Block any app or category — social, video, games, news, browsers - Pick your difficulty, from warmup arithmetic to competition-level - Choose your problem set: SAT, ACT, AMC, AIME, Putnam, or general practice - Earn time back per problem solved (you set how much) - Daily, weekly, and per-app limits - Schedule blocks by time of day (bedtime, study hours, work hours) - Dashboard with usage broken down by app, hour, and day - Custom block screen so it actually feels like a stop sign - Works with Family Sharing if you're setting it up for someone younger A few ways people use it: blocking social apps during work hours. Locking everything after 10pm with hard math. Pairing it with actual SAT prep so the time you would've spent scrolling becomes practice instead. Everything stays on your phone. No account, no login, no data sent anywhere. iOS 16 and up. iPhone only.
