About this app

Simple Coin Widget is a no-frills crypto tracker built for people who actually trade. Live prices, full candlestick charts with TA overlays, multi-language UI, and a one-time $1.99 VIP that unlocks unlimited coins + auto-news-push.

◆ WHY THIS APP?

Most portfolio apps either cost a subscription, lock your data behind an account, or hit you with ads the moment you open them. Simple Coin Widget:

✓ Stores everything on your device — no login, no sync, no account.
✓ Pulls prices from CoinGecko AND Binance so you see the real market, not a cached feed.
✓ Renders charts with the indicators traders actually use (MA, BB, RSI, MACD, Volume) — and lets you toggle each independently.
✓ Sends push alerts ONLY when your thresholds fire. Daily + per-hour caps are global, not per-coin.
✓ Speaks 11 languages so you don't need a translation pass to read your own portfolio.
✓ Costs $1.99 once. No subscription. The price shown on the paywall is the price you pay — Play Billing handles the rest.

◆ KEY FEATURES (FREE)

• Track up to 3 coins with quantity, buy price, watch-only mode.
• Real-time USD prices + 24 h % change on every card.
• 7 chart intervals (1 m → 1 month) with editable support/resistance levels, simple moving averages, Bollinger band overlay.
• Daily news search: 3 cached-fetch requests / UTC day for free users.
• Price alert types: price-up / price-down / PnL-up / PnL-down / stop-loss / 24 h % change.
• Home-screen widget with live price of any selected coin.

◆ VIP UNLOCK ($1.99 one-time)

• Unlimited coins in your portfolio.
• Up to 50 news searches / day (cached responses unlimited within 6 h).
• "Auto-receive latest news" — every 8 h we push the top headline for each tracked coin, deduped for 30 days.
• Pro chart indicators — RSI, MACD.
• Quick-set background refresh at any interval you like.
