Reliefr: personalized jokes

Jokes that actually land. Timed to when you need them, not served up on a feed. Reliefr isn't designed for scrolling. It's a notification app. A good joke shows up, the app shuts up, you get on with your day. You pick the times. Or set a window and let the app surprise you. Or plug in your calendar and get a joke 15 minutes before a hard meeting. Or link a wearable so the app can watch for stress spikes and bad sleep. Or tap the Rough Day button when you just need one now. Or all of the above. Humor matches your industry, age, and darkness preference (slider from 0 to 10, clean to unhinged). Thumbs up what you like, thumbs down what you don't, the stream tightens to your taste. Long-press any joke to see exactly why it landed. No black box. No "the algorithm wants you to know." No account. No ads. Nothing sold. Heart rate and sleep data never leave your phone. Calendar is read-only and stays on-device. Works against itself on purpose. No infinite scroll. No "just one more." No engagement loops. A good joke is 30 seconds. The rest of the minute is yours. Every delivery mode traces to actual research. Cortisol response to laughter. Dark humor and verbal IQ. Workplace micro-break meta-analyses. Citations at reliefr.app/science. "Therapy, but cheaper and worse." A humor app. Not a medical device. Not a therapy substitute. 18+.
