Never waste food again with smart expiration tracking

Never wonder 'is this still good?' again! UseByWhen.com instantly tells you how long 100+ household items last after opening. From ketchup (6 months) to mascara (3 months) - your pocket expiration expert. Reddit-validated with 22k+ upvotes!
Quick update: I'm actually working on a suite of simple, focused tools like this. UseByWhen was my first experiment in building single-purpose utilities that solve one problem really well.
My philosophy: instead of building one bloated app that does everything poorly, create multiple clean tools that each do one thing perfectly.
Next up: I'm launching PrecisionConvert.io (unit converter for professionals) and have a few other single-purpose tools in the pipeline.
For UseByWhen specifically, planning to add:
- More food categories (dairy, condiments, leftovers)
- Better mobile experience
- Meal planning integration
- Maybe a simple "what's expiring soon" widget
Would love to hear what other simple, single-purpose tools you'd find useful in your daily life. Sometimes the best solutions are the simplest ones!
Thanks for trying UseByWhen!
