Most productivity apps ask you to commit to forever. LifeLab asks you to test. LifeLab is a quiet, non judgmental space designed to help you run small, structured self experiments on your lifestyle, health, work, and routines. Instead of chasing streaks or feeling guilty about skipped days, you frame your goals as questions and collect evidence on what actually improves your focus, energy, and mood. HOW IT WORKS 1. Frame a Question Turn any goal or curiosity into a test. Example: “Will a 10 minute evening walk improve my sleep quality?” 2. Define a Minimum Version Set a micro goal for low energy days. Example: “Just step outside for 2 minutes.” 3. Choose Your Length and Rhythm Run your test for 3 days, 1 week, or 4 weeks. Track daily, weekly, or on specific days. 4. Check In and Log Mark occurrences as “Done”, “Minimum”, or “Skipped”, which is treated as valuable data, not failure. 5. Reflect and Learn Review insights at the end of the experiment and decide whether to continue, modify, or archive the routine. KEY FEATURES • No Streaks, No Guilt Skipping a check in is just useful data to understand why a routine did not fit. • Flexible Scheduling Perfect for non daily routines like Mon/Wed/Fri workouts or Sunday journaling. • Minimum Version Support Keeps you consistent without burning out. • Custom Metric Tracking Log energy levels, focus, sleep, or custom notes alongside your experiment. • End of Experiment Reviews Deep dive statistics and AI assisted summaries to help you make decisions. WHY LIFELAB? LifeLab is designed for overthinkers, creators, freelancers, and anyone tired of traditional high pressure habit trackers. We believe self improvement should feel like a calm personal laboratory, not a chore list. Start your first tiny experiment today and build a lifestyle tailored to who you actually are. SUBSCRIPTION & PRICING LifeLab offers an optional Premium subscription to unlock unlimited active experiments, advanced AI insights, and custom metrics. • Subscription automatically renews unless auto renew is turned off at least 24 hours before the end of the current period. • Manage your subscription and turn off auto renewal in your Account Settings.

Verdict
