FreeCBT is an open source thought diary for Cognitive Behavioral Therapy (CBT). Cognitive Behavioral Therapy (CBT) is the "gold standard" of psychotherapy and is widely considered to be one of the most effective, evidence backed treatments for depression, anxiety, and panic. If you go into just about any therapist or psychiatrist, CBT will likely be one of the first treatments they try. FreeCBT is a companion and self-help app for one of the most common formats of CBT. You may have heard it called "the three column technique" or "catch it, check it, change it." Your brain is really good at making you feel exactly what you're thinking. Often, we find ourselves thinking "automatic negative thoughts" that lead us to fume on something that may not be true. That can cause us to feel depressed or anxious. CBT helps you record "automatic thoughts," challenge them with cognitive distortions and then train your brain with an alternative thought. If you do it enough, you can change your thoughts, your moods and your behavior. FreeCBT, a fork of Quirk, is open source under the GPL. You can find the code on Github at: https://github.com/erosson/freecbt

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.
