About IT1ST
IT1ST builds and maintains the web utilities linked from this site. The aim is straightforward: make a useful task easy to complete, and explain what the result means.
Two tools, clear purposes
The Compound Interest Calculator explores a savings balance with a constant interest rate and optional deposits. Its help explains the rate conventions, compounding, timing and excluded costs. It cannot predict market returns or replace your provider’s terms.
The Choice Wheel makes a casual random selection from entries you provide. It offers list import, separate wheel and result text, and browser-local saving. It is not a certified draw service.
Access and data
You can use both tools without creating an account. Their basic forms work without JavaScript, using Cloudflare to process a submission and return a result. Browser saving is separate from an online account; clearing site data can remove saved wheels.
The tool pages explain their own handling of inputs and advertising. This hub has no ads or visitor analytics integration. Read the privacy and cookie information before entering data.
Questions and corrections
Contact IT1ST with the tool name, what you expected and what happened. Use example values rather than financial account details or sensitive personal information.
