    How Many Work Hours?

    Converts prices to work hours (w/ tax-adjusted wages) to make buys fee

    Tired of "bargain" regrets? This free Chrome ext flips prices to *hours worked* (monthly wages + Israeli gross/net taxes baked in). Set 24-72h timers w/ alarms, flag via 9 categories (green <2h clothes), track skips in wishlist/history stats. Bilingual EN/HE, dark mode, local-only—built for freelancers dodging burnout. Why now? My side-gig FOMO sparked it; v1.1's stats dash shows "saved 10h/month." Open-source GPL-3.0. 2-min demo: https://youtu.be/Idke_yZRwtY?si=ATknkqlB__NzR4bg Install: https://chromewebstore.google.com/detail/כמה-שעות-עבודה/fjjbjjipegofibokldobgfifbjipgkmp Makers/testers: Wage profile tweaks? Your "red flag" threshold? Feedback = v1.2 gold. #ChromeExtension #Budgeting #IndieMaker
