About

Shrimping

Features

Shrimping is a playful posture tracker that uses the motion sensors in your AirPods to detect when you're slouching — and nudges you to sit up straight. HOW IT WORKS Pop in your AirPods and calibrate your "straight back" position. Shrimping continuously monitors your head tilt and measures how much you're curling forward. When you slouch past your threshold for too long, you'll get a friendly (but firm) alert to uncurl. THE SHRIMP MASCOT A cute shrimp on your screen curls in real time to match your posture. Sitting straight? Happy shrimp. Slouching? Full crustacean mode. SMART ALERTS Set your own curl threshold and hold time. Quick coffee reach? Doesn't count. Sustained slouching? Time for an intervention. Get alerts with funny rotating messages like "Your spine just filed a formal complaint." DETAILED STATS Track your posture throughout the day with hourly breakdowns, weekly trends, and yearly summaries. Drill into any time block to see minute-by-minute detail. RUNS IN THE BACKGROUND Start a session and go about your day. Shrimping keeps monitoring your posture even when the app isn't on screen. You'll get push notifications when you need to uncurl. HOME SCREEN WIDGETS Add small or medium widgets to see your posture stats at a glance — connection status, session progress, and daily percentages. APPLE WATCH HAPTICS (PRO) Get a wrist tap on your Apple Watch when you slouch. No need to look at your phone. COMPATIBLE DEVICES - AirPods Pro (1st gen or later) - AirPods (3rd generation) - AirPods Max - Beats Fit Pro PRIVACY FIRST All posture data stays on your device. We never record audio. No tracking, no analytics, no ads. Optional iCloud sync keeps your data across devices. SHRIMPING PRO Unlock detailed stats, Apple Watch haptics, sound alerts, week & year history, and iCloud sync. Available as monthly, yearly, or lifetime purchase. Terms of Use: https://www.purplefox.io/shrimping/terms Privacy Policy: https://www.purplefox.io/shrimping/privacy
