Super application

Gabbichou · 14 years ago · v1.0.1

Cette application est très fiable mais nest toutefois pas assez developée, on aurait du pouvoir choisir soi-même les échelles.

Echt super - fast ein Oszi

AlexWK · 15 years ago · v1.0.1

Das App ist Klasse! Die darstellung sehr schnell. Wenn jetzt noch eine Triggerfunktion dazukäme waere ist ein LF-Oszi. Dafuer wuerde ich auch zahlen!

Nur brauchbar für rein sinusförmige Verläufe

suvlim · 15 years ago · v1.0.1

In der Praxis hat sich gezeigt, daß bei allen Frequenzgemischen, bei denen die Nulldurchgänge nicht durch die Grundwelle bestimmt werden, kein auch nur annähernd brauchbares Ergebnis angezeigt wird. Daher: ein nettes Spielzeug beim Stimmen von Instrumenten(?), aber im Leben eines "Technikers" wertlos.

Looks cool on store, but doesnt open.

fxn808 · 15 years ago · v1.0.1

If it would open on my iPhone 1st gen 3.1.3FW, it could give it a review, but it doesnt.

Works great!

JeffyPooh · 14 years ago · v1.0.1

Using the internal microphone, it provides an oscilloscope type display, along with relative amplitude and digital frequency display. Works great. The only thing I noticed was that the screen goes dark in accordance with the iPhone settings; ideally the app would hold off the screen dim function. This is a very minor point. Good app!!!

Great.

whistlefly · 14 years ago · v1.0.1

I was hoping Id fall on an app like that. I was looking for a frequency meter (in Hz) and this app has it. Plus the wavelength display and the dB meter; its a perfect application.

Definitely a toy

Using a concert pitch "A" tuning fork the display bounced all over the place and never displayed 440.
