Response from developer

Thanks for reporting this — you were right, and it wasn't your mistake. Version 1.6 fixes it: units now follow your device region automatically (imperial by default in the US), and several screens that ignored your selection — the dashboard last-scan card, the quick-edit velocity field, and the impedance, Snell's law and resonance calculators — now convert correctly. The "Imperial" option had also been mistranslated in 18 languages. Please update to 1.6 and check Settings → General → Units; if it still shows Metric, tap Imperial and the app will remember it. If anything is still wrong, email st67891@gmail.com with your device model and iOS version. And if 1.6 does fix it, I'd be very grateful if you'd consider revisiting your rating — only if you feel it's earned.
