Convert almost anything, right on your iPhone.
Email danielwaters@me.com with what you were doing and what happened. A screenshot helps. I aim to reply within two working days.
Common questions
What can I type on the Convert tab?
Plain words, the way you'd say it: “5 miles in km”, “how many cm in 12 inches”, “20 degrees C in F”, “£200 in USD and EUR”. Ask for several results at once with “and” or commas. On iPhones with Apple Intelligence, looser wording is understood too when you tap Go.
Can I use Siri?
Yes. Say “Convert units in Omnivert” or “Convert currency in Omnivert”, and Siri asks for the amount and the units. Both are also in the Shortcuts app. If Siri doesn't recognise the phrases straight after installing, open Omnivert once and give it a minute.
Where do the exchange rates come from?
HMRC's official monthly exchange rates, published on gov.uk. Omnivert downloads the current month's rates when it opens, and keeps them for use offline. Conversions between two non-sterling currencies go through sterling, so they can differ slightly from a live market rate.
How do I convert a recipe?
On the Cooking tab, tap the book icon. Import a screenshot or photo, a PDF, or paste a web page link, then choose Metric or US. Every measurement Omnivert recognises is converted and highlighted. Cups of dry ingredients such as flour and sugar become grams using typical densities, so treat those as close estimates. Tap the bookmark to save the recipe.
A file won't convert.
- Very large videos can take a while; keep Omnivert open until it finishes.
- Some formats can be opened but not created on iPhone. WebP images, for example, can be converted from but not to.
- If a document still fails, email me with the file type and what happened.
Can I change the tabs?
Yes. Tap the gear at the top of any tab, then Tab Order, then Edit, and drag them into the order you like. The first tab is the one Omnivert opens on. Within a tab, the sliders icon lets you reorder or hide sections.
