Price alerts that ring on silent
Most price alerts are ordinary notifications, so silent mode and Do Not Disturb hold them back. The alerts that get through are the ones delivered as an alarm — or that your phone is explicitly told to let through.
Why price alerts go quiet on silent
When a trading or tracking app sends a price alert, your phone usually treats it like any other notification. That means the same rules apply: the ringer switch, Do Not Disturb, Focus modes, and per-app notification settings all decide whether it makes a sound. On a silenced phone, the answer is usually no.
Alarms are different. Your alarm clock still rings on silent because the operating system gives alarms their own path. A price alert that's delivered as an alarm — rather than as a notification — can behave the same way.
On Android
Android gives apps separate notification channels, and alarms have their own category that silent mode and Do Not Disturb treat differently from regular notifications. To make any alert app more reliable on Android:
- Check the app's notification channels (Settings → Apps → the app → Notifications) and make sure the price-alert channel is allowed to make sound.
- Allow it through Do Not Disturb if you want it to break through, by adding the app to your DND exceptions.
- Turn off battery optimization for the app, so the system doesn't delay or drop its messages.
- Allow "Alarms & reminders" if the app asks for it — that's the permission alarm-style apps rely on.
VIIJEL on Android: critical levels use an alarm-style alert that rings and repeats every 15 seconds until you answer. It's already ringing real Android phones in testing.
On iPhone
On iPhone, Focus and the silent switch hold back normal notifications. You can let specific apps through a Focus (Settings → Focus → choose a Focus → Apps), and apps can mark some notifications as Time Sensitive, which you can allow to break through Focus.
Truly ringing through the silent switch requires Apple's Critical Alerts entitlement, which Apple grants to a small number of apps after review. VIIJEL will request it for the iPhone release — and won't claim it until Apple grants it.
A quick checklist before you trust any alert
- Send yourself a test alert with the phone locked, on silent, and in Do Not Disturb.
- Check it still arrives after the app has been closed for a few hours.
- Find out what happens when the price feed drops — does the app tell you, or go quiet?
- Keep your truly important levels few, so an alarm always means something.
Questions
Because most price alerts are delivered as normal notifications, and silent mode, Do Not Disturb and Focus modes all mute normal notifications. Alarms follow different rules, which is why an alarm-style price alert can still ring.
On Android, you can allow an app through Do Not Disturb, and alarm-style alerts are treated differently from regular notifications. On iPhone, you can allow an app through a Focus, but ringing through the silent switch needs Apple's Critical Alerts approval.
On Android, critical levels ring and repeat until you answer. On iPhone, VIIJEL will request Apple's Critical Alerts approval for the iPhone release and doesn't claim silent-mode ringing until it's granted.
