Bitcoin Ticker (+Widget) 暗号通貨＆取引 アプリ 向け Android 説明
A deliberately tiny, ad-free and tracker-free Android home-screen widget showing the Bitcoin price in EUR and USD.
Features
- EUR and USD price, 24h change, 24h high/low and last update time
- Manual refresh plus automatic background refresh (about every 15-30 minutes, subject to Androids battery scheduling)
- Tap the widget to open a focused chart screen: 10 minutes, 1 hour, 24 hours, 4 days, 14 days and all time, with touch-to-inspect values
- Choose to display EUR, USD or both - in the app and the widget. Tap the currency line at the bottom of the app to cycle through EUR → USD → both.
- Bilingual interface (English and German)
- No account, no ads, no analytics, no tracking, no unnecessary permissions
Data sources
Price data comes from the public CoinGecko market endpoint with a public Coinbase fallback. Historical chart data uses Blockchain.com and Frankfurter. No API key or exchange account is needed.
Open source
The full source code is available under the MIT license. If you like the app, you can support it with an optional donation (link in the app footer) - the app is and stays free, without ads.
