DoseAngel

DoseAngel is a free, non-commercial harm reduction tool built for the community, that helps you plan ahead and keep track of where you are in your trip.

Most risky decisions happen while under the influence, when it's hard to track time or know if you're rising, at peak, or coming down. DoseAngel helps you plan ahead, see what's active in your system, and understand your current state before you consider redosing, significantly reducing the risk of overdose or dangerous combinations.

Key features:

Plan ahead: map out your doses before you start and see predicted peak and comedown times, so you know roughly what to expect

Live state tracking: a real time graph shows what's active in your system right now, including what stage you're in, coming up, at peak, or coming down

Combination checker: look up any two substances to see documented interaction risk before you combine them

Risky combination warnings: get an automatic warning if what you're about to take interacts with something already active, before you confirm

Customizable substances: adjust onset, peak, and offset timing for any bundled substance, or build your own from scratch

Everything is stored on your device, no internet connection required. No accounts, no data collection, nothing ever sent anywhere. Free, with no in-app purchases.

DoseAngel is a planning and reference tool, not medical advice. It does not diagnose or treat any condition, and it does not calculate or recommend dosages. Always check with a doctor in addition to using this app, and before making any medical decisions. In an emergency, contact your local emergency services immediately.
