The crypto market never sleeps. Bitcoin can rip 5% at 3 a.m., a tiny altcoin can double while you're in a meeting. Anyone trying to follow it manually ends up one of two ways: either missing the move, or chained to a chart. The fix is simple — make the phone tell you the moment a price hits the level that matters.

This guide walks you through exactly how to receive crypto price alerts on Android: from install to first notification ringing, including all the permissions that typically break alarms on real-world phones — Samsung, Xiaomi, Motorola, Realme.

Why phone alerts make the difference

Your phone is the only device that's with you 24 hours a day. Unlike a browser tab or a spreadsheet on a desktop at home, it rings in your pocket, on your pillow, at the gym. For a market that runs 24/7 without pause, it's the only monitoring format that actually makes sense.

There are three practical ways for a phone to alert you on crypto:

  • Push notification — arrives in seconds, even with the app fully closed. The main mechanism.
  • Native alarm sound — rings loudly, like an alarm clock, ideal for "critical" alarms like major breakouts.
  • Home-screen widget — price always visible, without opening any app. Good for passive tracking.

A well-built app combines all three. If it only sends you a silent push while you're sleeping, it'll fail exactly when it matters.

Why push beats polling

Apps that check prices "every so often" (polling) can take minutes to ping you. Real push via FCM (Firebase Cloud Messaging) arrives in under 2 seconds. On a resistance breakout, those minutes are the difference between a clean entry and a late one.

Step by step: setting up your first alert

Step 1

Install Alarm Crypto from Google Play

Download the app for free from the Play Store. The install is small and asks for no contact, photo, or other sensitive data. The app does not sell user data — it lives off Premium subscriptions and that's it.

Step 2

Sign in with email

Email-only login, no phone number, KYC, or exchange account required. Login is what syncs alarms across devices: switch phones and you recover all your alarms instantly.

Step 3

Grant the right permissions

On first launch, the app asks for notification permission, battery-optimization exemption, and (on some OEMs) autostart. Accept all of them — without these, Android may kill the app process in the background and alarms simply won't arrive.

Step 4

Create the alarm

Tap the + button, search for the token (BTC, ETH, SOL, DOGE — over 2,400 supported), pick "price above" or "price below," type the trigger price, and confirm. The current price shows in real time on the screen so you can pick a realistic target.

Step 5

Test with a tight value

Best practice to validate everything works: create an alarm with the trigger 0.5% from the current price. Within minutes it fires, and you confirm the sound rings, the notification arrives, the vibration works. Better to find out now a permission is missing than to miss a real move.

The Android permissions you need to enable

This is where most crypto alarm apps fail on real phones. OEMs apply aggressive battery-saving layers, and each one differently. The good news: Alarm Crypto has a dedicated flow that detects your manufacturer and takes you straight to the right settings screen.

The three essential permissions:

  1. Notifications enabled — Settings → Apps → Alarm Crypto → Notifications → allow all. Without this, FCM doesn't deliver.
  2. Battery optimization disabled — Settings → Battery → Optimization → Alarm Crypto → "Don't optimize." This stops the system from killing the background process.
  3. Autostart allowed — only appears on Xiaomi, Realme, Oppo, and some Samsungs. Battery settings → Background apps → Alarm Crypto → allow.
Brand by brand

Xiaomi and Redmi require explicit autostart. Samsung has "Sleeping Apps" — remove Alarm Crypto from that list. Motorola is more permissive; usually just disabling optimization is enough. Realme and Oppo inherit Xiaomi's behavior. iPhone doesn't have this issue because iOS handles push differently, but Alarm Crypto is Android-only for now.

Alert types you can configure

Getting an alert that "BTC hit $100,000" is just the most basic case. Alarm Crypto supports several trigger types, and combining them well expands what you can actually track:

  • Price above/below — the classic. Useful for buy targets, sell targets, and support/resistance levels.
  • Ordinals floor price — denominated in BTC, for Bitcoin collections like NodeMonkes, Bitcoin Puppets, Quantum Cats.
  • Fear & Greed Index — an alarm on "below 20" catches extreme panic zones (historically a good time to accumulate).
  • Altcoin Season Index — an alarm on "above 75" signals altcoin season, "below 25" signals Bitcoin season.

When the alert doesn't arrive: troubleshooting

If you set an alarm and it didn't fire when expected, it's usually one of five causes. From most to least common:

  • Battery optimization re-enabled — some OEMs turn it back on by themselves after an Android update. Check Settings → Battery.
  • "Do Not Disturb" active — silences even vibration. Add Alarm Crypto to the exceptions list, or use the native alarm sound (which bypasses Do Not Disturb).
  • Notification volume at zero — notification volume is separate from ringtone volume. Adjust in Settings → Sound.
  • Token isn't covered by the monitored exchanges — the app only pulls prices from Binance, Coinbase, Kraken, Bybit, Bitget, and MEXC. If the token only exists on a small DEX, there's no data.
  • Google push delayed — rare, but happens on corporate networks that block FCM. Switching from Wi-Fi to 4G usually fixes it.

Extra features worth turning on

  • Crypto widget on the home screen — price of any favorite straight on your launcher, refreshes by itself. Doesn't replace alerts, but great for quick checks.
  • Altseason widget — visual gauge of the Altcoin Season Index, takes the same footprint as a clock.
  • Alarm sharing — you generate an 8-character code with your alarms and send it to someone for a one-tap import. There's a dedicated import guide.
  • Favorites list — for tokens you just want to track, without turning them into alarms. Shows up with price and 24h change in a separate tab.
Pro tip

Don't overdo the number of alarms. Setting 30 alerts on the same token just clutters your screen and breeds notification fatigue — you start ignoring all of them. Focus on 3 to 5 key levels per asset: a buy target, a sell target, and a psychological stop.

Recap: what to remember

  1. Install Alarm Crypto from Google Play
  2. Sign in with email — no KYC, no phone number
  3. Allow notifications, disable battery optimization, enable autostart if your OEM requires it
  4. Create a test alarm 0.5% from the current price and confirm it rings
  5. Set up your real alarms — on price, Ordinals, Fear & Greed, or Altcoin Season
  6. Use the widget and favorites list for passive monitoring

Done. From here your phone does the heavy lifting: it pings you when the market moves to the level you defined, and you just decide whether to act. For a full tour of every feature, or to see why this is currently the most complete crypto app on Android in 2026, check the related guides below.
