PrepperApp vs Spectrum SDR (RTL

PrepperApp helps you stay calmly prepared for a power cut, a storm, a flood or another emergency. One number shows how many days your household can manage, you make an emergency plan together, and SOS and first aid are always close at hand. TODAY One honest number: this is how many days your water and food will last. The app counts 3 litres of water and 2,000 kcal per person per day and compares that with your government's advice. You see your weakest point and your next step straight away. SUPPLIES Add products by scanning the barcode, photographing a receipt or taking a photo of your shelf. For each category you see what you have, what expires soon and what is past its date. The shopping list helps you fill the gaps. ONE EMERGENCY PLAN FOR THE WHOLE FAMILY Write down what you will do in a power cut, a fire, a flood and other situations. Agree on meeting points, make an evacuation plan and work through the emergency checklists. Share your supplies, emergency plan and family card with your household. With "Are you safe?" you let them know you're fine in one tap. SOS AND FIRST AID One tap on the red SOS bar opens the emergency menu: call the emergency number, share your location, open guided first aid or text your emergency contacts. The app never calls by itself. The CPR timer gives the rhythm with a tick and tells you out loud when to give breaths. The first aid guide, tick bite help and emergency protocols are all in one place. SOS and first aid also work when you're not signed in. OUTDOORS Record your walks and look back at them on the map: your route in gold, the elevation profile, your pace per kilometre and your photos. Keep a trip day by day, with your stops, photos and walks on one map. LEARN AND THE COACH A learning path of twelve lessons, guides and practice questions help you step by step. The Coach answers questions about your own preparation and always names its source. ON YOUR IPHONE AND APPLE WATCH While you record a walk, distance and time show on your Lock Screen, with Pause and Photo. Widgets for your Home Screen and Lock Screen, search in Spotlight, Siri shortcuts in four languages and Control Center buttons for SOS and Start walk. On your Apple Watch you have your days, a compass, SOS and your emergency contacts on your wrist. YOUR DATA You create a free account with your email address, so your supplies and household move safely to a new phone. Your medical profile, medication and document vault stay on your phone. Family chat is end-to-end encrypted. No ads, and our servers are in the EU. FREE, WITH PRO AS AN EXTRA The core of the app is free. Pro adds unlimited supplies, all emergency plan scenarios, the document vault and the Coach's AI help, among other things. You buy Pro once, with no subscription. In English, Dutch, German and Spanish, with government advice for the Netherlands, Belgium, Germany, Spain, the United Kingdom, the United States and Australia. PrepperApp does not replace the emergency services. In acute danger, always call the emergency number.
