About this app

Stop missing profits while you sleep. Sentinel wakes your phone with a full-screen Crypto Alarm when Bitcoin or any coin hits your price.

Sentinel is a Cryptocurrency Tracker built for people who need alerts that actually break through. Set exact targets, % moves, or dual boundaries across major exchanges—then choose ALARM or STANDARD per alert.

FULL-SCREEN WAKE-UP ALARM
. When a move matters, Sentinel doesn’t “politely notify.” It wakes your device.
. Wake Up Alarm that can trigger even from deep sleep
. Full-screen alert over the lock screen with a big STOP button
. Custom alarm sounds (Classic, Digital, Chime, Beep, Clock)
. Adjustable volume + timeout so you stay in control
. Perfect as a Crypto Alarm for overnight breakouts, support/resistance tests, and volatility spikes.

PRICE ALERTS BUILT FOR TRADERS
. Set alerts like you trade—fast, precise, and repeatable.
. Exact Price Alerts (above or below your target)
. Percentage Alerts from a reference price
. Dual Boundaries: watch both upper AND lower levels at once
. Recurring Alerts with cooldown timers (no one-and-done alerts)
. Use it as a Crypto Price Alert, Trading Tracker, and always-on Stop Loss Tool for key levels.

BINANCE + MULTI-EXCHANGE TRACKING
. Watch the market where it actually trades.
. 5 major exchanges: Binance, Coinbase, Kraken, Bybit, KuCoin
. Search thousands of coins
. Filter by exchange, favorite your watchlist, compare prices
. If you need a reliable Binance Alert without juggling apps, Sentinel keeps it in one place.

TWO NOTIFICATION MODES: YOUR URGENCY, YOUR RULES
. Pick the right intensity for each alert:
. ALARM MODE: full-screen, wake-from-sleep, unmissable
. STANDARD MODE: regular push notifications for casual tracking
. Use ALARM for entries/exits and liquidations. Use STANDARD for “keep an eye on it” levels.

ALERT HISTORY THAT SAVES YOU FROM GUESSING
. Triggered alerts don’t vanish.
. Grouped by date (Today / Yesterday / older)
. Filter unread
. Batch mark-as-read or clear all
. Auto read-tracking as you scroll
. This makes Sentinel a better Trading Tracker when you’re reviewing moves and missed triggers.

REAL-TIME CRYPTO PRICES
. Fast price checks without waiting around.
. Live price polling with trend indicators
. Responsive UI for quick scanning
. Get Real-time Crypto Prices that support your decisions, not your anxiety.

WHY SENTINEL (NOT REGULAR PUSH NOTIFICATIONS)
Most alerts fail for one reason: they’re too easy to ignore.
Sentinel is different because it uses:
. FULL-SCREEN INTENT to display over the lock screen
. WAKE FROM SLEEP behavior so your device actually wakes up
. Alarm sounds + vibration so you feel it, even at night
. Push notifications are fine for news. For trading levels, you need a Stock Market Alarm-style wake-up—built for crypto.

PRIVACY FIRST. NO ADS. NO TRACKING.
. Trading is personal. Sentinel keeps it that way.
. No ads, no tracking, no data selling
. Minimal permissions (only what’s required for alerts)
. Delete your account anytime from Settings


PERFECT FOR
. Day traders who need unmissable alerts
. Swing traders watching support/resistance
. Long-term holders tracking milestones
. Anyone who wants a real Crypto Alarm instead of a missed notification

Download Sentinel now and set your next alert—before the market moves without you.
