How booking works
- Create an account and write your ad: business name, headline, short text, optional image and your link.
- Pick a spot, choose whether it appears across the site, in one category, or on chosen calculators.
- Choose dates and pay per day, or buy a package of views. The price is shown before you pay.
- Pay by card. Nothing is charged until you confirm the total.
- Your ad goes live automatically as soon as the payment completes and runs on schedule.
What we accept
Ads are always labelled, never placed over calculator results or between inputs and buttons, and never shown on developer or text tools. We do not accept adult content, gambling, misleading claims, click-bait wording, or anything that imitates our own buttons and results.
