Web tools & development

Small, useful tools for the web.

PlatformOwn builds and hosts free web tools that answer one question properly, alongside custom web applications for clients. Everything below is live and free to use — no sign-up, no account.

Free tools

Each of these takes a question people genuinely search for and answers it with a real calculation, rather than dumping a table of raw data.

Meeting Time Planner

The working hours two cities actually share, shown in your own clock. Handles daylight saving and half-hour timezones, and when there is no overlap at all it still gives you the least-bad times to call.

About

PlatformOwn is an independent web development studio. We build web applications for clients and publish free tools of our own, all running on our own infrastructure: containerised applications behind nginx, deployed through a pipeline that tests each release before it goes live.

The tools are static sites — every page is generated ahead of time, so they load quickly and keep working even when an upstream data source is unavailable.

Get in touch

Whether it's a project enquiry, a correction to a holiday date, or a bug in one of the tools — email is the fastest way to reach us. Pick whichever fits and your mail app will open with the subject filled in.

Your name, email and message are sent to us so we can reply. Nothing else is collected and we don't add you to any mailing list. See the privacy policy.

Prefer your own mail app? contact@platformown.com — we aim to reply within two working days.

If you spot a holiday or timezone that looks wrong, please do tell us — the tools are only as good as the dates behind them, and corrections from people on the ground are the fastest way we find mistakes.
