Moving from mycrometer.fieldmycologist.uk
Mycrometer’s home is now mycrometer.app. Browsers keep each website’s data separately, so your scales, samples and photos don’t move over by themselves. It takes a minute:
- Open the old address, go to the Measure tab and press Back up everything…. Keep the .zip file.
- Open mycrometer.app/web, go to Measure, press Restore backup… and choose that file.
- If you’d added the old address to your Dock or Home Screen, remove it and add the new one.
Common questions
- My spores come out about 4× too big (or too small).
- The photo is almost certainly using the scale for another objective. Check the scale chosen under This photo. Each objective, and each eyepiece, needs its own scale.
- A photo won’t open.
- It’s probably HEIC, the iPhone’s default format, which only Safari can open. Open Mycrometer in Safari, set the iPhone to Settings → Camera → Formats → Most Compatible, or re-save the photo as JPEG or PNG. Photos larger than 100 megapixels are refused.
- Where is my data?
- In the web version, it’s in your browser on that device and nowhere else. Clearing the browser’s website data deletes it, so use Back up everything now and then, and keep your original photos. In the Mac and iPhone app, it’s on your device, and with Pro it syncs through your own iCloud account.
- Does it work without internet?
- Yes. Once you’ve opened the web version (or installed it to your Home Screen or Dock), it works offline.
- Where do I get the Mac or iPhone app?
- On the App Store, very soon. It’ll be one free download for Mac, iPhone and iPad.
- Can I use it on Windows, Android or Linux?
- Yes. The web version runs in any modern browser, and you can install it like an app from Chrome or Edge.
- How accurate is it?
- Usually to within a few tenths of a percent, but only if the calibration is right. Use a good micrometer photo, keep the camera setup unchanged, and measure spores lying flat and in focus. Optical resolution limits everything: about 0.2–0.3 µm with a good 100× oil objective.
- I bought Pro. How do I get it on my other devices?
- Open the app on the other device, signed in with the same Apple Account, and choose Restore Purchases.
