Epokka

Epokka counts down to the next Cardano epoch — and nothing else. Every epoch on Cardano lasts exactly five days. Epokka works out where you are in the current one and shows you the time left, entirely on your device. COMPLETELY OFFLINE Epokka does not request the INTERNET permission. It cannot reach a network at all — you can check that yourself in the app's permission list. No server, no account, no sign-in, no analytics, no ads, no tracking. The countdown is derived from the published Cardano protocol parameters using arithmetic your phone can do on its own, so it stays exact in airplane mode, in a tunnel, or on a watch left at home. Because nothing can be sent anywhere, there is nothing to leak. WHAT YOU SEE • Time remaining, time elapsed, or percentage complete — your choice • A ring gauge or a plain progress bar • The current epoch number and the date the next one begins • Eight accent colours, including a monochrome option HOME SCREEN WIDGET Place as many widgets as you like. Each one is configured on its own: its colour, what it displays, and whether it draws a ring or a bar. A widget you never configure simply follows the app's settings. WEAR OS A standalone watch app and a watch face complication. The watch computes the countdown itself, so it stays right even when your phone is out of range or switched off. TABLETS The layout adapts to large screens rather than stretching a phone design across them. REMINDERS An optional local notification before an epoch boundary, or exactly at it. Scheduled on the device, like everything else here. 64 LANGUAGES Epokka is fully translated into 64 languages, including right-to-left scripts. Epokka is an independent app. It is not affiliated with, endorsed by, or sponsored by the Cardano Foundation, IOG, or Emurgo. "Cardano" and "ADA" are used descriptively to identify the network the app tracks. Epokka shows no balances or reward amounts, holds no keys, connects to no wallet, and provides no financial advice.
