Harm Reduction Sisters (HRS) is a non-profit organization focused on providing harm reduction services and support to people who use drugs (seehttps://harmreductionsisters.org/). HRS participants can use this secure mobile app to anonymously contact Harm Reduction Sisters at any time (24/7/365). Through ongoing community outreach HRS provides supplies such as naloxone (aka Narcan, to reverse opioid overdoses), safer use kits for both injection and smoking, HIV and STI testing, drug checking services (FTS and FTIR), telehealth access to buprenorphine, and educational resources aimed at reducing the negative health and social consequences associated with drug use. These services are available in downtown Duluth, MN at the Damiano Center but also through our mobile outreach unit. With this mobile app you can find out where HRS services are available in real-time, you can request for those service to meet you where youβre at, or you can send private chat messages to staff at HRS for mutual aid and ongoing support. In addition, app users can sign up for notification alerts for when the HRS mobile services are in your region, financial incentives that are available at HRS, and spikes in overdoses or identification of harmful trends in the drug supply. Finally, we are continually updating the video library on the app to provide participants with information about how to administer naloxone, conduct drug checking, and medications that help to manage substance use. This mobile app aims to increase access to harm reduction services in northern Minnesota by providing a safe for people who use drugs to connect with life-saving services and support
Dose Sure

DoseSure helps you stay organised around a single question: did I take my scheduled dose today? DASHBOARD β’ Large, obvious action when todayβs dose is not yet logged. β’ After logging, see a green confirmation with the exact time. β’ Undo if you tapped by mistake. HISTORY & RULES β’ Scroll a clean history grouped by dose day. β’ Set your medication name, the time window that counts as βon timeβ, and a day reset so late-night doses stay on the correct calendar day. IMPORTANT DoseSure is for personal organisation only. It is not medical advice, not a medical device, and not a substitute for care from a qualified clinician or pharmacist. Privacy-minded by design: your dose entries and settings are stored on your device. Optional cloud or family features, if added later, will be disclosed in the app and App Store listing before you enable them.
