CALL369 VIDEO · BETA
Your calls. Your space.
Create a Call369 room, share its link and approve your guest. Camera, microphone and camera switching are within reach.
Open Call369 Video ↗Two-person beta. Links last one hour. Relay is not configured yet, so some networks may not connect. Testing on two phones is still pending.
PERSONAL SPAM LIST
Bring your personal spam list.
Transfer and update your spam list by number and name using CSV. Preview changes before importing; duplicates merge while personal labels and allowlisted numbers are preserved. Export numbers alone or numbers with names.
Requires your own list file. No direct connection to the private Truecaller database.
A warning. A reason. A next step.
Three independent options: a distinct sound, spoken advice and a text hint. Silent mode and Do Not Disturb are respected.
Hospital, accident and family emergencies
Dedicated scenarios cover urgent surgery payments and paying an injured person so they will not contact the police. Advice: pause payment, call your relative on a known number and verify independently.
AI Voice · experimental
Choose audio or start the microphone. The local AASIST model checks several segments for possible synthetic speech. Audio is not uploaded. The result cannot establish lies and can be wrong.
Microphone recording is started manually and runs for up to 60 seconds while the screen is open; analysis starts after about 8 seconds. Android normally blocks cellular-call audio from ordinary apps. Import a recording made by your phone instead. Phrase checks use text; there is no automatic transcription. Voice-model reliability on Hebrew, Russian and new generators is unverified.

Make it fit your day.
Keep important numbers close. Set your own rules for unknown calls.
Speed dial
Assign numbers to keys 2–9. A long press opens confirmation, then hands the number to the system Phone app.
Quiet hours
Choose days and times to silence unknown incoming calls. Contacts, favourites and allowed numbers remain exceptions.
Call reminders
Choose a preset interval or your own date and time. Edit reminders later; Android may delay the notification.
Background updates
Enable daily signed CallShield complaint updates. Wi-Fi is the default; a failed update keeps the last verified database.
Unanswered-call reminders
Optionally remind you after 15, 30 or 60 minutes. Android permissions are required; declined calls can count as unanswered. Manual reminders remain available.
Quick reply and voicemail
Open an SMS draft from a notification or your carrier voicemail settings. You confirm sending; your carrier determines voicemail availability and pricing.
Your own voice greeting
Record up to 60 seconds, listen, record again and save M4A. A failed replacement preserves the old greeting. Set up your carrier greeting separately; audio is not automatically uploaded to voicemail.
A free list, built right in.
Downloaded lists check incoming numbers locally. Each source shows its actual +972 coverage.
CallShield included
51,368 numbers from public complaints are bundled. The feed signature is checked on your device. Snapshot: 10 October 2026; no +972 entries in this snapshot.
PhoneBlock offline
Connect your free account with a personal API key and download a list. Later updates fetch changes with source rate limits respected. See the date, +972 count and complaint threshold.
Your call rules stay personal
A community match warns but never blocks a call by itself. Names come from contacts and your directory. No public reports or contacts are uploaded.
The +972 format is supported; complaint coverage depends on each source. There is no complete free Israeli owner directory here. No match does not establish safety.
Quiet hours schedule
Silences unfamiliar callers during selected hours. Days refer to the start of each period; overnight periods are supported. Uses device local time. Contacts, favorites and allowed numbers are exempt. Explicit personal blocks still apply. Requires Android caller ID role and blocking enabled.

PERSONAL PROTECTION
You decide who gets through.
Create personal blocks and exceptions. Each number card shows where the name comes from and which rule applies.
- Search your contacts, personal labels and imported CSV directory.
- Block individual numbers, set prefix rules and add personal spam labels.
- Favourites, notes, categories and a history of Call369 screening events.
Start in three steps.
Android 10 or later. Install the APK directly from this site.
Download APKGuardian is a beta. Automated build and interface checks were run; microphone recording, speech output and calls still need verification on your phone.
- Download and open the APK on Android. If prompted, allow installation for the app you use to open the file.
- Open Call369 and select it as your caller ID and call screening app in Android’s system prompt.
- Optionally allow contacts and notifications. Set up blocks, exceptions and quiet hours.
Where do caller names come from?
Your contacts, personal labels and imported directory. CallShield and PhoneBlock add complaint information, not a complete worldwide name directory like commercial caller-ID services.
Where is my data stored?
Contacts, rules, history, text and audio stay on your phone. PhoneBlock receives a key and IP when connecting or downloading; manual number checks also send a SHA-1 hash that is not anonymous. The microphone starts by your action. Spoken advice uses an installed offline voice. During video calls, audio and video are transmitted to your guest over WebRTC. The service stores temporary connection data, not call recordings. IP addresses are used to establish the connection. When you sign in, your email, account number and payment records are stored on the server; your private spam list is not uploaded.
How do I update an older version?
Install the new APK over your existing Call369 app. The package name and signing key are unchanged. You can export personal rules in Settings before updating.
Does it replace the Phone app?
Confirm outgoing calls in your system Phone app. Call369 records screening events, not the phone’s complete call history.
Is this a lie detector?
No. Text checks match known wording and show the evidence. AI Voice estimates synthesis signals, not whether words are true. Neither result proves fraud or safety.
