LastSip is a caffeine cutoff calculator that tells you when to stop drinking coffee, tea, or energy drinks based on your sleep time, metabolism, and sensitivity so you can fall asleep faster and wake up refreshed.











After nearly 11 months in the job market, I decided to build something fun, creative, and personal.
I've always been highly caffeine sensitive, and I couldn’t find anything simple that accounted for my bedtime, metabolism, or lifestyle. So I built LastSip: a caffeine cutoff calculator that adjusts to the person using it.
The iOS app adds full-day planning, saved routines, deeper personalization, and cutoff reminders. If caffeine affects your sleep like it does mine, I hope this helps!!
Happy to answer any questions about the build, wrapping with Capacitor, or deploying on AWS.
*NOTE: Also, I am actually looking for ~10 people to test the Android version of the app for the Play Store submission requirement. I will send a free coupon for the app to those 10 kind souls who are willing to help!!
