Happies

Read full description

Happies is the to-do app that actually makes you want to do your to-dos. Most to-do apps just store your tasks. Happies helps you prioritize them. You rate each task by urgency and importance — Happies automatically sorts them into four clear buckets, so you always know exactly what to work on next. DO IT NOW — urgent and important. Handle these today. DEEP WORK — important but not urgent. Schedule focused time. UPCOMING — delegate or do later. FOR LATER — park it here. Every task you complete earns XP. Level up. Build momentum. Watch your Done List grow. Say goodbye to Sunday Scaries and hello Sunday Happies! $4.99 unlocks unlimited tasks forever — or try free with up to 5 tasks. No ads or subscriptions.

Systemiq is the AI-powered systems thinking tool for curious minds. Understand how anything works, why it exists, what could break, and what happens next. Most people see the surface. Systemiq helps you see the system underneath. Whether you're exploring how a stock market functions, why hospitals are designed a certain way, diagnosing a real-world problem, or planning a major goal, Systemiq turns your questions into structured system maps in seconds. ANALYZE ANY SYSTEM Ask about anything: business, technology, biology, infrastructure, psychology, economics, society, and more. Systemiq breaks complex systems into components, flows, inputs, outputs, dependencies, bottlenecks, and failure points—so you can actually understand what’s going on. REVERSE ENGINEER REALITY Why does the QWERTY keyboard exist? Why are supply chains structured the way they are? Why do certain systems outperform others? Systemiq reveals the hidden trade-offs, forces, and design decisions that shape the world around you. PLAN LIKE A SYSTEMS THINKER Turn goals into execution systems. Describe what you want to achieve, and Systemiq helps structure the moving parts: priorities, risks, phases, dependencies, and actionable next steps. DIAGNOSE WHAT’S BROKEN Car won’t start? Team communication keeps failing? Workflow keeps collapsing? Systemiq helps you trace the breakdown, identify root causes, and understand where the system failed. EXPLORE WHAT-IF SCENARIOS What happens if gravity doubles? What if AI replaces a major industry? What if remote work becomes permanent? Simulate cascading consequences and explore second-order effects with AI-guided systems analysis. BUILD CONNECTED UNDERSTANDING Knowledge shouldn’t live in isolated fragments. Systemiq helps connect ideas across domains, helping you recognize patterns, relationships, and recurring system principles. FOR PEOPLE WHO WANT TO UNDERSTAND, NOT JUST MEMORIZE Systemiq is built for thinkers, builders, students, entrepreneurs, problem-solvers, and endlessly curious minds. Because everything is a system.
