ReadiCache is a preparedness tracker for your household. It answers one question you should not have to guess at: if something goes wrong, how long are you covered? WHAT IT DOES - Track food, water, medical supplies, hygiene, power and other essentials in one cache - See how many days of food and water you actually have, not just a pile of boxes - Scan a barcode to add an item in seconds, with product details filled in for you - Get reminded before things expire, so stock rotates instead of quietly going bad - Set readiness goals and watch your coverage against them - Organise supplies across storage locations and see them on a map - Attach photos, notes and quantities to anything you store WORKS WHEN NOTHING ELSE DOES An emergency app that needs a signal is not much of an emergency app. ReadiCache runs entirely on your device. You can download map regions ahead of time and browse them with no connection at all. PRIVATE BY DESIGN Your cache is stored on your device and encrypted. There is no account to create and nothing to sign in to. We cannot read what you store, because it never reaches us. FREE AND FULL ACCESS Free includes up to 20 items, 3 storage locations and 1 offline map region. Full access is a single purchase, not a subscription. It removes every limit: unlimited items, unlimited storage locations and unlimited offline map regions. Buy it once and it stays yours, including after a reinstall.
