Scams, telemarketing and robocalls stop ringing. Sentinel decides before your phone rings: people you know get through, the rest is silenced or blocked. All on your phone, without internet.
Then R$9.90/month or R$59.90/year, for up to 5 phones. Cancel anytime on Google Play.
How it decides
Rules in order, like a firewall for your phone.
Each call goes down your list until a rule matches. The first match decides whether it rings, rings silently or is blocked, and the history keeps the reason.

Blocked
Why? Blocked by “No telemarketing”: the 0303 prefix is reserved for telemarketing.
Everything that matters, free
Peace without missing what is important.
Scam protection
Blocks hidden numbers, telemarketing and numbers flagged as scams, stops spoofed caller IDs and the trick of imitating your own number.
Spoofed IDs rejected by the carrier
Same area code and same start as yours
Unknown callers ring silently
No telemarketing
The 0303 prefix and hidden numbers are blocked. Block a number, or the start of one, with a single tap.
Sleep and work in peace
Sleep, Work, Vacation with a return date and Driving: modes that turn on and off by themselves.
Never miss what matters
Emergencies always ring, and so does whoever calls twice in 3 minutes. Waiting for a delivery? Let unknown numbers ring for an hour.
You know why
Every decision comes with its reason. Test a number to see what would happen if it called now, and get a morning summary of who called while you slept.
Your way
Create your own rules, set rules per SIM, share a rule or a mode with a link and back everything up to a file.
Inside the app
Simple to use. Clear about every call.
Sleep Silence at night, with exceptions.
Filters Ready-made protections, one tap each.
History The reason behind every call.
Test a number Know before it calls.
Family, with consent
Protection, not surveillance.
Your parents see exactly what you can do before they agree, and choose what to share. Their contacts and messages never leave their phone.
Subscribe to Family and create your family in the app. Install Sentinel on their phone, tap “This phone will be protected by a relative” and scan the QR code shown on yours. They agree, and you manage their rules from your phone. It takes about a minute.
Do my parents need an account?
No. Only you, the administrator, use an Eagle account. Their phone joins with the QR code and keeps working without internet.
What do I see from their phone?
Only what they allow on the agreement screen: who rings and the rules, the calls Sentinel filtered in the last 30 days, scam alerts and a weekly summary. Never their contacts or messages, and they can switch any of it off.
Is Sentinel free?
Yes. Scam protection, no telemarketing, silencing unknown numbers, Sleep, the history with the reason for each decision and Test a number are free, with no ads. Plus adds automations such as Driving and Work, and Family protects up to five phones.
Does it block WhatsApp calls?
No app can: Android only lets call blockers filter regular carrier calls. Sentinel shows how to silence unknown callers inside WhatsApp itself.
Why does Android ask me to pick Sentinel as the caller ID and spam app?
That role is what lets an app decide on a call before the phone rings. Your contacts are only used on your phone, to recognize the people you know.
Does it need internet access?
No. Every decision is made on the phone itself, without internet. An Eagle account is optional and only needed for backup, sync and the Family plan.
Is there an iPhone version?
Sentinel starts on Android. iOS gives call blockers far fewer options; an iPhone version will come when it can keep the same promise.
I already subscribe to Eagle Pro. Do I get Plus?
Yes. Sign in to Sentinel with your Eagle account and Plus is unlocked at no extra cost.
