Who's calling from that unknown number? With Nummeropslag you can look up any Danish phone number in seconds and instantly see whether to pick up โ company, spam rating or private person. HOW IT WORKS Enter an 8-digit Danish number and get the whole picture in one place: who's behind it, a spam score, a trust meter and reviews from other people. WHAT YOU GET โข The company behind the number โ straight from the official, public CVR business register. Real data, not scraped phonebooks. โข Person or business? โ instantly see whether an unknown number belongs to a registered company or a private individual. โข Spam & scam check โ a clear spam score and trust meter before you answer. โข Community reviews โ read what others experienced and leave your own: spam, scam, telemarketing, company or private. โข One-tap reporting โ flag spam and fraud numbers and help everyone else. โข Spam labels in the Phone app โ known spam numbers are labelled and the worst are blocked automatically, even offline. Turn it on under Phone โ Call Blocking & Identification. โข Google-verified business info โ address, industry and ratings where available. โข SMS filter โ messages from unknown senders that match known spam numbers are moved to Junk automatically. Enable it under Settings โ Apps โ Messages โ Unknown Senders. BUILT INTO IPHONE โข Siri & Shortcuts โ say "Look up number" to jump straight to search. โข Spotlight โ start a lookup from your Home Screen. โข Share a number โ share from Phone, Messages or Contacts to look it up. โข Universal links โ nummeropslag.dk links open directly in the app. โข Widget & Control Center โ start a lookup from the Home Screen or Control Center. โข Landscape & iPhone Duo โ the app uses the whole screen, including the inner display on iPhone Duo and Split View. REMINDERS (OPTIONAL) iPhone does not show anything by itself once a call has ended. So โ if you allow notifications โ the app can send one quiet reminder a while after a lookup where we could NOT work out who the number belonged to. You can write who it was straight from the notification. There is always a "Don't know / didn't answer" button that sends nothing. We ask at most once per number, and we only ask for permission once the app has already been useful. You can decline and keep using everything else. PRIVACY ABOVE EVERYTHING Most caller-ID apps upload your entire contact list. Nummeropslag never does. โข We never copy your phonebook. โข We don't collect personal data and we sell nothing. โข Only anonymous, aggregated signals. GDPR-friendly by design. DATA SOURCES โข CVR โ the official Danish business register. โข The Danish Number Register (SDFI, CC0 open data) for carrier and number type. โข Anonymous reports from real users. Free to use. Available in Danish, English and Ukrainian. Look up a number and leave your first review โ the app gets smarter as more people join. nummeropslag.dk

Verdict
The clearest difference is in-app purchases: Nummeropslag at none against ServiceBog's 4. Nummeropslag also leads on ads (none vs shown) and update cadence (every 2 weeks vs every 6 weeks). On price and device support there is nothing between them.
