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.
