1.4
July 29, 2026
Thank you for using PartyWise! This update focuses on accuracy, timing, and looking out for one another. - More accurate combination info. We expanded and refined our reference data so combination checks resolve more completely. - Timing-aware reminders. Opt-in, on-device notifications help you follow a session from start to finish. Fully private, nothing leaves your device, and reminders stay discreet on your lock screen by default. - Well-being check-ins. Optional notifications to take a break, cool down, and stay hydrated in moderation. - Look out for each other. A new shareable summary lets you give a trusted friend the context and simple first-aid reference to help if needed. You choose exactly what's included, and nothing is ever shared automatically. - Refinements & fixes. Clearer information cards, corrected calendar and unit display, and a polished layout so key actions are always in reach. As always: educational reference only, not medical advice. Everything stays private on your device.
