NoCall

A missed call from an unknown number leaves two choices, ignore it or call back and hope it isn't a scam. NoCall adds a third. You type the number into the search box on nocall.io, or the name of a company you think is calling, and see what other people reported. Results show how many reports a number has, the call type such as telemarketing or scam, a risk score and the comments. The comments often name the company behind the call.

The website lookup needs no account. NoCall says it shows only what the community reported about a number and never personal data about private individuals.

The free iOS and Android app identifies known spam calls as they come in and shows ads. Pro is a single €2.99 payment rather than a subscription. It blocks reported calls before the phone rings, can block whole number ranges and international numbers, and removes the ads. On iPhone it also moves texts from reported numbers into the junk folder, with filters for links, short senders, unknown senders and messages in other languages.

Pro includes an AI check for suspicious messages. You choose whether to send the message text or a screenshot, and the privacy policy says the text is stripped of phone numbers, email addresses, card numbers, one-time codes and similar details before it goes to Google Gemini or xAI Grok. Screenshots go as they are, so the policy suggests cropping personal details first. Call blocking and the automatic iPhone SMS filter run on the device, and NoCall says it never uploads your contacts.

NoCall comes from Byteguard Sociedad Limitada in Badajoz, and Spain is its home ground. The homepage example uses a +34 number, the scam quiz draws on official warnings in Spain, and the privacy policy describes the search as covering numbers in Spain. There are language editions for dozens of other countries, but a lookup is only as good as the reports behind it, so expect thinner results where fewer people use it. The site counts 283,551 blocked numbers and about 2.1 million comments.

The free guides are worth reading even without the app. Recent ones cover AI-cloned voices of relatives asking for money, fake buyers on Wallapop and Vinted, and the forwarded WhatsApp code that hands over your account.
