What QuietCall does
Block calls by prefix
Enter a full number or its first digits and check the range for the chosen country. Keep wanted numbers on your allow list.
Number notes and caller names
Save your own name and private note for a number without giving access to your address book. Enable caller identification to show the name you saved. Private notes do not appear on incoming calls.
Sender and word filters for SMS
Sort eligible messages using sender numbers and words you choose. This applies to messages from unknown senders passed to the app by iOS.
On-device storage and iCloud backup
Numbers and rules stay on your device. Optionally back up and restore rules and number notes separately in your own iCloud Drive.
Questions and answers
Are GoyoCall, 고요, 고요콜 and QuietCall the same app?
The app described here is QuietCall, named 고요콜 in Korean. If you searched for GoyoCall or 고요, use the App Store link with app ID 6809385497 to identify the same app.
Does QuietCall automatically detect spam calls?
No. It applies the numbers and prefix rules you choose. Optional number groups are not a verified spam database and may include wanted calls. Check the range before saving.
How can I block calls by the first digits?
Choose a country, enter the prefix and select the groups you need from the range preview. Enable QuietCall number blocking in iPhone Settings, then apply the list in the app.
Does it look up unknown callers in a public directory?
No. Caller identification shows the name you saved in your number notes. It does not look up other people in a shared phone directory.
Is it free? Is there a subscription?
Blocking and 100 number notes are free; the app has ads. One-time purchases can remove ads or unlock the note limit and remove ads. There is no subscription. Apple shows local prices before purchase.
Are my contacts or messages sent to a server?
The app does not read your full address book or call history. Message content is checked on your device, not saved or sent to an operator server. See the privacy notice below for optional iCloud backup and app advertising data.
Which devices and languages are supported?
An iPhone with iOS 17 or later supports English, Korean, Japanese, German, Spanish, French and Simplified Chinese. Language support does not mean the app is sold in every App Store region.
Privacy
Your rules stay with you.
Phone numbers and rules are stored on this iPhone and shared only with the app's call and message extensions. We do not read your Contacts or call history. Message content is checked on the device and is not saved or sent to a server. You can remove each rule in My rules.
Number notes and caller names
Names, phone numbers, private notes and favorites are stored on your device. Only the number and display name you choose are provided to iOS caller identification; private notes are excluded. The share extension reads only the number or contact card you share, not your full address book or call history. You can edit and delete entries in Number notes. Optional iCloud backups include names, numbers, notes and favorites.
Operator
QuietCall is operated by GOYO WORKS (고요웍스). For support or privacy questions, contact gulp-science-large@duck.com.
Advertising
The main app uses Google AdMob. Google may process device, IP address, ad interaction and diagnostic data to serve ads, prevent fraud and meet legal requirements. From version 1.0.1, we may use the advertising identifier for personalized ads, subject to your advertising consent and iPhone tracking permission. Without permission, non-personalized or limited ads may be shown. You can change tracking permission in iPhone Settings > Privacy & Security > Tracking. Where required, Google presents consent choices. You can revisit available choices from Settings. Call and message extensions do not contain the advertising SDK.
Backup in your iCloud
Selected blocking rules and number notes are backed up separately to your iCloud Drive. Note backups include names, numbers, notes and favorites. Apple’s storage policies apply. Automatic backup can be turned off.
Optional support
Blocking and 100 number notes are free. Settings has Remove ads, Unlock notes + remove ads, and Support QuietCall menus. They use the existing ad-removal product and the existing bundle that unlocks notes and removes ads. Storage supports up to 5,000 entries and 24MB. Owned features show Purchased and can be restored with the same App Store Apple Account. If you already own ad removal, the bundle is a separate purchase at the full displayed price without deduction of your earlier purchase. Optional support is available before and after feature purchases. Each tip is a separate payment and adds no features. There is no subscription. Apple displays local prices and handles payment; QuietCall does not receive card details.

1. Add call rules in My rules.
2. Open Settings → Apps → Phone → Call Blocking & Identification. On iOS 17, Phone is directly in Settings.
3. Enable QuietCall - Number blocking.

For messages: open Settings → Apps → Messages → Unknown & Spam (the name varies by iOS version). Enable filtering of unknown senders and select QuietCall as the SMS filter. Only one message filter can be selected. Add sender or word rules in My rules.
No rules are enabled for you automatically. Wide patterns can block wanted numbers. Hidden numbers, FaceTime, iMessage and calls handled by other apps are outside this app's control. iPhone does not give QuietCall a call history or blocked-call count.
Allowed numbers come first
QuietCall always excludes allowed numbers from its call blocking and message filtering.
Block 070-7744, but allow 070-7744-1234: that number is excluded. Its messages are allowed even when a keyword matches.
What iPhone controls
QuietCall cannot override iPhone's blocked contacts, carrier filters or other calling apps. An allow entry cannot force those systems to accept a call. Hidden caller IDs cannot be matched. iPhone controls how numbers in Contacts are treated.
Message filtering covers eligible SMS/MMS from unknown senders. It does not filter iMessage or messages from contacts. Alphanumeric sender names cannot match a numeric allow entry.
The list was not fully applied. An older list or only part of this list may remain. Check Settings and apply again.
