In 2024, NumBuster introduced the feature to customize the main app icon. Our users immediately loved it. Haven’t tried it yet? Give it a go now!

On the home screen, find the “App Icons” section and explore a wide selection of free icons, along with special icons available for NumCy (our in-app currency).

On 🍏 iOS, only the main icon can be changed. On 🤖 Android, starting in the autumn, users can customize all three home screen icons (yes, there are three!): the main icon, the quick access icon for phone calls, and the icon for SMS.

✨ Personalize your icons for holidays or seasons. For example, to welcome spring, we’ve added a set of icons that will brighten your device’s home screen with vibrant colors and flowers. 🌼

🤔 Did you know that NumBuster on Android identifies phone numbers even in WhatsApp and Viber?

Now, when you receive a call through a messenger, the NumBuster widget immediately shows information about the number — So, you decide whether to answer the call or block it.

🔹 What does the widget show?

✅ Rating — whether the number is safe or not.

✅ Reviews — what other users say about the number..

✅ Tags — for example, “call center” or “spam”.

Open the NumBuster app home screen, enable the Caller ID in Messengers feature, and allow the app widget to appear over other apps.

With NumBuster, you always know who’s calling you! 🔥

An unknown number can appear during a call, in an ad, chat, or on a business card.

The NumBuster phone number card gives a general idea, but that may not be enough when the contact seems suspicious.

In such cases, turn to NeurOwl — an AI developed by NumBuster to analyze numbers. It summarizes user feedback, analyzes behavior, tags, and ratings to provide insights.

NeurOwl knows more by accessing data not shown in the app UI — analytics, number connections, system-level signals, and more. It detects hidden patterns and is constantly updated.

📋 How to get a NeurOwl opinion:

1️⃣ Open the number card in NumBuster
2️⃣ Tap “NeurOwl”
3️⃣ Select “New Opinion”
4️⃣ Get a detailed analysis

📌 When it's most useful:

✔️ When you want a well-grounded opinion
✔️ When working with unknown or suspicious contacts
✔️ When you need to spot hidden behavioral signals

NeurOwl Opinions are available with a NumBuster subscription and offer much more than a basic check.

Your phone number card in NumBuster is always open to feedback — and that’s great as long as comments remain respectful and constructive. Sometimes, though, what seems like a “review” may turn out to be unpleasant or unfair.

🔒 In such cases, the block feature is here to help. Blocking a number means the user can’t reach you or leave new comments. If a comment is already visible, you can delete it manually and block the number to avoid further issues.

This simple tool is useful for anyone who values clean, controlled communication:

💬 If you use your number for work, your app reputation affects your professional image — especially if you take orders or provide consultations.
👤 For personal use, managing feedback helps maintain comfort and peace of mind.

‼️ Please don’t misuse delete or block on constructive feedback — it may harm your rating. Try replying first; the author might revise their opinion.

👍 With NumBuster’s block feature, you decide which comments and calls are part of your communication.

How to message on WhatsApp, Telegram, or Viber without adding the number to contacts

There are times when you want a quick WhatsApp, Telegram, or Viber message but don’t want to save the number for a one-off interaction. This frequently occurs when dealing with clients, couriers, or temporary inquiries, resulting in contact lists cluttered with rarely used numbers.

Skip saving numbers! NumBuster opens messenger profiles directly - fast and convenient.

📌 This is especially useful when:

• the conversation is onetime only
• you want to keep your contacts clean and organized

💡 How to use it:

1. Open the NumBuster app
2. Type the number into the search bar or pick it from the call log
3. Tap the WhatsApp, Telegram, or Viber icon in the bottom menu

NumBuster simplifies starting chats with unfamiliar numbers in messaging apps; no more phonebook clutter.

📩 You get a message from an unknown number. It warns of suspicious activity on your account, unpaid debts, or a “final notice” about a fine, payable today only with a discount.

The link may look real — but might include tiny symbol swaps that are hard to spot.

At first glance, it seems legit:
— a trusted organization
— urgent tone
— an “official” link

But it’s phishing. The site is fake. Your data ends up with scammers. You enter login, password, or card details – and lose account or money.

❗️It’s all designed to cause panic. Messages like this often appear to come from institutions you trust — making it easy to react emotionally.

What should you do?

⚠️ If the SMS is from an unknown number, check it in NumBuster — especially if it has a link.

Many of such numbers are flagged by users for spam, fraud, or suspicious activity.

With NumBuster’s built-in SMS manager, you get extra protection — the app automatically detects and filters dangerous messages.

🔒 Sometimes, an incoming call appears as “Unknown” or “Hidden number.” You can’t call back, see the number, or identify the caller. These calls might happen once or keep repeating — but the question is: who’s calling?

📌 One way to reveal it is by setting up call forwarding — to voicemail or another number. In some cases, this exposes the original number, especially if the call isn’t answered. Forwarding to a number on a different carrier often works better.

❗ Note: Many carriers charge for forwarding. Always check pricing and billing before enabling it.

🟡 How NumBuster helps: If the forwarded call goes to a phone with NumBuster, the number is instantly checked. You’ll see call stats, user flags, and feedback. That helps identify if it’s a call center, marketing team — or someone suspicious.

Even if the number was hidden, forwarding may uncover it. With NumBuster, you get a real picture based on community experience.

Phone scammers often spoof numbers, making them look almost identical to bank or service lines. The difference can be tiny–one wrong or replaced digit. It's hard to spot, especially if you're expecting a call. These are hard to spot, especially if you’re expecting a call.

A familiar-looking number lowers your guard. You answer, thinking it’s real, and risk giving away personal data to scammers pretending to be official staff.

NumBuster helps detect risky numbers. The app identifies callers and provides key details:

Tags: See if other users marked it as trustworthy, helpful, or suspicious.
Rating and reviews: Each number has a social trust rating based on user feedback.
Up-to-date database: The crowd-powered base is constantly updated, helping detect even new scam numbers.

If a number seems familiar but feels suspicious, stay cautious. Check any number in NumBuster. Users may have left reviews or reported repeated calls. This helps you react quickly and avoid scams.

✈ Peace of mind on vacation matters — especially when your loved ones are traveling. Still, uneasy thoughts arise. Who’s renting out the apartment? Who’ll meet them at the station? Who’s the local coordinator?

🏠 Hosts may show up unannounced, demand extra fees, or behave aggressively.
🚖 Drivers may be rude, drive recklessly, or ignore agreements.
🗺 Guides could be complete strangers posing as professionals.
👷‍♀️ Teen workers may face withheld pay, no contact, or document issues.

Travel often brings surprises — but some risks can be avoided with one simple step.

📌 A phone number is a digital fingerprint. NumBuster shows trust ratings, real feedback, and past complaints.

Booking a rental, hiring a driver, messaging a guide, or sending your teen to work? Check the number in NumBuster first. A quick check can make all the difference in keeping your people safe.

In many countries, illegal or unregulated taxi services are becoming increasingly popular. They’re cheaper and easier to arrange — but along with the savings comes a loss of guaranteed safety. You don’t know who’s behind the wheel.

Check the driver’s phone number in NumBuster before your ride:
• Rating — shows the number’s reputation;
• Reviews — real feedback from people who have taken a ride;
• Tags — smart labels that help you stay informed.

How to check:
1️⃣ Copy the driver’s phone number received with your booking;
2️⃣ Enter it in the NumBuster search bar;
3️⃣ Review the information on the phone number page.

This way, you can assess how safe it is to agree to the ride.

📱 Before buying a new SIM card, think about this: who used that phone number before you?

Many carriers resell phone numbers. The new owner may start receiving calls and messages meant for the previous subscriber — from “friends” to debt collectors. Sometimes, the number was even involved in shady activity or spam campaigns.

To avoid such surprises, check the phone number in NumBuster.

🔍 Here’s how:
1️⃣ Enter the number in the NumBuster search bar;
2️⃣ Review its rating, user feedback, and tags;
3️⃣ Pay attention to complaints, unusual activity spikes, or negative comments.

That way, you’ll know whether this number is worth taking — or if you’re better off choosing another one.
No debts, no spam, no bad history attached.

🎮 Online games are now a major part of children’s lives. In-game chats, messages, and team discussions may seem harmless, and parents often focus mainly on screen time. However, it’s in these spaces that a child may be offered a “great deal,” asked for an SMS code, or encouraged to move the conversation to a messaging app.

⚠️ Key Risks:
– unauthorized charges for “donations” or subscriptions
– attempts to break into gaming accounts, email, or social media
– overly personal communication from adults
– spam and intrusive calls

🛡 NumBuster helps you:
• check the phone number messaging or calling your child
• see if there are complaints about that number
• block suspicious contacts promptly
• block SMS from unknown numbers on Android
• identify contacts on WhatsApp and Telegram (on Android, when the phone number is visible)

With NumBuster, parents always know who their child is communicating with and help make online gaming safer.

Scammers have started using a new scheme: blocking bank cards without the owner’s involvement, followed by blackmail.

Fraudsters can block your card without your participation. They call the bank pretending to be the client, use basic personal details, and manage to get the card blocked “at the owner’s request.” After that, you may receive a message or phone call hinting that the problems are only beginning and suggesting that you “come to an agreement.”

‼️ Important: your money remains in your accounts. The pressure is based on stress and the feeling of loss of control over your funds.

If you encounter this scenario:
— do not negotiate;
— contact your bank immediately through official channels;
— ignore threats and warn your relatives.

NumBuster helps you understand who is behind a phone number. If a number already has complaints from other users, it’s best not to engage.
Stay calm and verify information through official channels. This helps protect you and your loved ones.
