Child Resus Calc
APK
This App provides fast calculation of endotracheal tube size, defibrillation energy and drug doses for Paediatric Resuscitation and Rapid Sequence Intubation (RSI) in a pre-hospital paediatric emergency situation. THIS APP IS INTENDED TO BE USED BY SELF-EMPLOYED DOCTORS/PHYSICIANS. THIS APP IS AN INFORMATION TOOL ONLY AND NOT A SUBSTITUTE FOR PROFESSIONAL JUDGEMENT. Always enter the child’s weight if possible. Guessing the weight by New APLS Formula is just an approximation. The actual weight may differ markedly. I did not (yet) implement such a thing as a maximum weight nor a maximum dose. E.g. if you enter a weight of 500 kgs the App will calculate 2000 Joules defibrillation energy, 5 mg Adrenaline, and so on.

Circuit Training (PFA)
APK
Privacy Friendly Circuit Trainer is an Android App that supports the user during their circuit training session. It provides a configurable set of timers for the exercises and the rest phases as well as multiple other features. Workout Timer After configuring the set of timers in the main menu you can start the workout routine by pressing the start button. The workout view has animations and sound output features which can be turned on and off inside the settings menu. Motivation Alert The app can show you motivation alerts to remind you of planned workout sessions. You can define the time of day and the notification texts inside the settings menu. Block Periodization When scheduling the timers you may also choose the block periodization feature. This feature allows you to configure longer, separate breaks in between the exercises. This way the workout can be split into multiple high intensity workout cycles. Workout History The app can collect statistics about your performed workout sessions. The collected data comprises of the time spend working out and the calories burnt while exercising. The accuracy of the calories calculation can be improved by configuring the necessary user data in the settings menu. The collection of this data can be deleted as well as turned on and off inside the settings menu. Exercise Sets The app allows you to create your own Exercise Sets for the circuit training. Therefore you can combine your own exercises to exercise sets. The image assigned to an exercise is displayed during the workout. In addition, the exercise sets can be repeated during a workout. For this you can set the number of rounds before starting the workout. How does Privacy Friendly Circuit Trainer differ from other similar apps? 1. No permissions Privacy Friendly Circuit Trainer does not require any permissions. The selection of images is done by a task to the gallery so the app does not have any access to the device's storage without the user's control and interaction. 2. No advertisement Many other free apps in the Google Play Store dazzle annoying advertising and also shortens battery life. Privacy Friendly Circuit Training is part of the Privacy Friendly Apps group developed by the research group SECUSO at Technische Universität Darmstadt.

Contact Diary
APK
Contact Diary is a simple app that allows you to keep a record of the people you have met and the events you have attended to recently. In the undesired event that you test positive for COVID-19, Contact Diary is a place where to quickly find who you must warn about the situation. How it works Every day Contact Diary will prompt you to insert the events you have attended and the people you have been with during the day. Through some simple forms you will be able to store the essential information about your contacts, in case you need to retrieve it. Just that. Simple, right? ;) Features Configurable notification time, so the prompt does not interfere with your daily workflow. Show only potentially risky contacts. Automatic removal of entries older than 15 days. Export your latest contacts to a CSV file that you can share with the authorities. JUST ONE PERMISSION, that needed for the app being able to notify you after device restarts. Nothing else. In particular, NO INTERNET permission. The information entered is yours, and it never leaves your device. FAQ - Wait, isn't this what Governments' contact tracing apps are doing? No. The goals of Governments' contact tracing apps and of Contact Diary are inherently different. Governments' contact tracing apps notify you when you have been at risk, and Contact Diary serves to remember who you must notify if you test positive. - Is this app BETTER than Governments' contact tracing apps? No. Governments' contact tracing apps may account for contacts that you may not be aware of, like the person sitting in a neighboring table at a restaurant, or that other person using the same bus to go to work. Contact Diary IS NOT A REPLACEMENT TO GOVERNMENTS' CONTACT TRACING APPS. - Is this app WORSE than Governments' contact tracing apps? No. Government's contact tracing apps crucially rely on all persons interacting to have the app in order to do proper notifications. With Contact Diary, you just need yourself to keep track, and you can easily notify people (or places) that do not use conventional contact tracing apps. - Will this app share the information I input? NO. The app has no permissions, so there is no way that it can connect to the internet. The information you insert will never leave your device. Even more, entries in the diary are automatically eliminated when they become older than 15 days. Support If you find a bug, have an idea on how to improve Contact Diary or have a question, please visit the Contact Diary project page on GitHub: https://github.com/apozas/contactdiary
