Features no other spam blocker offers.
RoboKiller, Hiya, Truecaller, and YouMail block spam. None of them built any of these.
Enter a second PIN under pressure and the app opens to a completely blank history — no blocked numbers, no logs, no trace. Your real data stays safe and returns with your real PIN.
✕ Not in: RoboKiller · Hiya · Truecaller · YouMail
Tap once when walking alone, on a first date, or in an Uber. If you don't check in before the timer ends, your trusted contacts are automatically alerted — no action needed from you.
✕ Not in: RoboKiller · Hiya · Truecaller · YouMail
Call Vault automatically separates the people you know from junk. Open a blocked message from someone you actually know, check it, and reply — without ever unblocking them. The number stays blocked. Your reply goes through. No other blocker does this.
✕ Not in: RoboKiller · Hiya · Truecaller · YouMail
A personal, pinned thread for notes, reminders, and photos. Stored entirely on your device, never synced or uploaded. Add titles, pick a card color, search across notes. Attach photos from camera or gallery. Password Protected.
✕ Not in: RoboKiller · Hiya · Truecaller · YouMail
One tap exports a complete harassment report — every call and text from a number with timestamps and block reasons — formatted for law enforcement, HR, or legal counsel.
✕ Not in: RoboKiller · Hiya · Truecaller · YouMail
Change the app's home screen icon and name to Calculator or Notes. Nobody looking at your phone will know it's there. Tap it, enter your PIN, open Call Vault.
✕ Not in: RoboKiller · Hiya · Truecaller · YouMail
Lock any individual conversation with its own PIN, independent from your app PIN. Locked threads are hidden in the inbox. All message bodies encrypted on-device with AES-256-GCM.
✕ Not in: RoboKiller · Hiya · Truecaller · YouMail
All seven features are included in Premium ($24.99/yr) — still cheaper than RoboKiller ($89.99/yr), Hiya ($49.99/yr), and YouMail ($71.88/yr).

Everything you need to go silent.
All blocking runs on your phone — your calls, contacts, and block list are never uploaded. Community spam reports are anonymous and opt-in.
Set a second PIN for high-pressure situations. Entering it opens the app to a completely empty, normal-looking screen — no blocked numbers, no logs, no trace.
Tap once when walking alone, on a date, or in an Uber. If you don't check in before the timer ends, your trusted contacts get an automatic alert.
Designate up to 3 people who are silently notified if you ever enter your Duress PIN. Turns privacy into a personal safety net.
Every time a call is blocked, your phone plays a short alert tone — a satisfying audio cue confirming the block worked. On iOS, delivered as a post-block notification alert with sound.
When an unrecognized caller rings through, your phone plays a two-tone chime — a subtle heads-up before you answer so you can decide whether to pick up. On iOS, delivered as a notification with a chime sound.
Open blocked texts to check for false positives. On Android, read them directly inside Call Vault. On iOS, blocked texts land in Messages.app → Filters → Junk — tap "View in Messages" inside Call Vault to go there.
Reply to a blocked sender directly without ever unblocking them — all from inside Call Vault. Requires Call Vault as your default SMS app. Android only — iOS disables replies from the Junk folder.
One tap blocks every call and text from an area code — 800, 212, or any prefix you choose. Individual exceptions go on your Always Allowed list.
Set quiet hours — work time, bedtime, or weekends — and unknown calls are silenced automatically. No action needed once it's configured.
Choose a discreet home screen icon for privacy. Change Call Vault's icon to Calculator or Notes style — nobody looking at your home screen will know it's there. On iOS, the icon changes but the app name remains Call Vault.
Add as many numbers, keywords, and area codes as you need. No caps, no tiers within the tier — unlimited is unlimited.
A complete messaging experience — SMS, MMS (images, GIFs, video, PDF), group threads, emoji reactions, starred messages, scheduled send (long-press to pick a time), draft saving, contact search, media gallery, and customizable bubble colors.
Call Vault automatically separates the people you know from junk. Reading and replying to blocked messages from people you actually know is Premium — no other blocker does this.
A personal, pinned thread for notes, photos, and reminders. Stored only on your device — never sent, never synced, never uploaded. Attach images from your camera or gallery. Password Protected.
Lock any conversation with its own PIN — independent from your app PIN. Locked threads show as hidden in the inbox. Supports change and removal from the conversation menu.
When a PIN is set, all message bodies are encrypted on-device using AES-256-GCM with a PIN-derived key. Even if someone extracts your phone's storage, your messages are unreadable.
Search and send GIFs from GIPHY directly in any conversation. Browse trending GIFs or search by keyword — sent as MMS attachments.
Set call or text history to delete itself after 30, 60, 90, or 365 days. Runs silently in the background — no manual cleanup needed.
One tap generates a complete harassment documentation report — every call and text from a number, with timestamps and block reasons — ready to share with law enforcement, HR, or legal counsel.
Unknown calls are silently held — robodialers that detect silence hang up automatically. Real people stay on the line. You get a notification to answer or block. No prompts, no hassle, no server.
A detailed breakdown of every call and text blocked — by category, area code, keyword, and time. Every week, a Shield Report summary lands in your notifications showing exactly what was stopped.
One-tap links to report scam calls and texts directly to the FTC Do Not Call registry — the agency that fines illegal robocallers. Report straight from any blocked entry in your call or message log.
Export your call or message history as a CSV file — opens directly in Excel or Google Sheets. Useful for legal documentation, harassment reports, or personal records.
Every blocked call is time a scammer tried to steal from you. Call Vault tracks it — showing the cumulative hours and minutes reclaimed since install. Grows every time a spam call is dropped.
A 0–100 rating that shows how protected your phone is right now, based on your active settings — call screening, SMS protection, PIN lock, and more. At a glance, see exactly what to turn on to reach 100.
Blocked calls are dropped before your phone makes a sound — using your phone's built-in call screening. Silent, instant, and automatic.
Add words like "warranty," "claim," or "IRS" and any text containing them is stopped before you see it — even from numbers not on your block list. On iOS, requires a one-time tap in Settings → Messages → Text Message Filtering.
Blocked calls are silently dropped before your phone rings. No missed-call alert, no disturbance. The caller hears nothing unusual.
1,300,000+ spam numbers sourced directly from the FTC's Do Not Call complaint database — the US government agency that fines illegal robocallers millions of dollars. US and Canada users only; international users rely on community-reported spam. Updated monthly.
Schedule a fake incoming call to arrive at a time you choose — a convincing, no-questions-asked exit from any uncomfortable situation.
Schedule a fake outgoing text to appear at a time you choose — a natural-looking message that gives you a reason to step away.
Key numbers — your doctor, your kid's school, emergency contacts — always ring through. No blocking rule can ever silence them.
Got a spam call or text? Report the number anonymously to the Call Vault community. Numbers that receive 3 or more independent reports are added to the Spam Shield Database for all users. No personal data is ever included.
Export your entire setup — block list, keywords, whitelist, settings, and logs — as a JSON file. Restore it on any device instantly. Your data, your control.
On Android 11 and later, every call shows whether the carrier network verified the caller ID or flagged it as a possible spoof — a green Verified badge or amber Possible Spoofing badge. No cloud lookup, no setup.
Features without a platform badge are available on both iPhone and Android. Android features rely on Android-specific APIs not available on iPhone — including real-time call audio interception, the default SMS app role, and carrier STIR/SHAKEN verification. PREMIUM features require a subscription — $3.99/mo or $24.99/yr, billed through Google Play. Cancel anytime.
