Self-control, made physical.

for AndroidNoDial — an outgoing-call blocking app

Get it on Google Play

01What it is

Make the numbers you swore off truly uncallable.

NoDial physically blocks outgoing calls to the numbers you register. No need to delete contacts — even if you remember the number or dial it by hand, the call won't connect. A wall stronger than willpower, for the moment of impulse.

02How it works

1Register a number
2Protection on
3Calls won't connect

Registered numbers cannot be deleted from the app. The only ways out are closing your account (takes effect immediately) or uninstalling. This is by design — so your weakest moment can't undo your strongest decision.

03Pricing

Blocking your first number is free. Every feature is included, and no payment info is required to start.

Want to block more than one number? Upgrade to Premium ($4.99/month, auto-renewing) — purchase and cancel anytime through Google Play.

04FAQ

Q. Can I unblock a registered number at any time?
No — and that is the point. To unblock, you must close your account (takes effect immediately) or uninstall the app.
Q. What about emergency numbers like 110 or 119?
Emergency calls always go through. Emergency numbers are excluded from blocking by Android's own framework, and NoDial adds a second layer of protection so they cannot be registered in the first place.
Q. Does the app collect my personal information?
No email address, name, or home address is required. The phone numbers you register are transmitted only in hashed (SHA-256) form — we never see the original numbers.
Q. When am I charged?
Blocking your first number stays free forever. You're only charged if you choose to upgrade to Premium, billed monthly through Google Play.
Q. How do I cancel Premium?
Cancel anytime from your Google Play subscriptions manager. Premium stays active until your next renewal date. After that, blocking continues for your free-tier number (you can choose which number to keep in the app's settings; if unspecified, it defaults to the first number you registered). The rest are paused and reactivate immediately if you resubscribe.
Q. What happens if I switch phones?
There is no account-transfer feature (this is by design). Simply register again on your new device.
Q. Does it work on iPhone?
Android only (Android 10 or later).
