OsciPrime Oscilloscope

Good, but ability to increase width of trace as well as adding levels of persistence afterglow would be a massive improvement!

Exceptionally well done and useful.

Well done! Very versatile. UI could use a bit of improvement, one suggestion is to make some of the icons toggle. A better & more descriptive HELP screen within the app, as many capabilities have to be discovered. For those complaining how to use. NOTE; On 1st run... Read the 1st & 2nd screens carefully, BEFORE pressing "Got It" ..They are Help screens, explaining the icons. Helps if you know what & how to use an oscilloscope. TO START - use the "Play/Pause" icon

Looks like great software. but I need some instructions to help me to turn it on and get started using it. How do you keep the signal output on screen to be continuous instead of it stopping automatically stopping after 4 or 5 seconds. Please answer this for me. If it won't do this I would like a refund on my purchase. Tony Wheat

Hello...could you please send me the schematics to build a custom external probe thanx. Want it to plug to a samsung galaxy s5 if possible. Thanx again

We had a late 2000's Chevy topics that had erratic behavior with both engine and trans. Made a homemade cable from phone Mic input to trans input speed sensor. With a voltage limit/control inline. For being such a crude signal source cable. The graph was great and precise. I was able to take screenshot to prove trans had to come out. Someone had put too long of a bolt in bookbinding. Denting torque converter. The dent showed up on graph even though you couldn't see it when engine barred over.

Great oscilloscope program.

Very interesting tool

Great support.

I just hooked up a voltage divider like so: Gnd - 2.2KOhm - Mic In - 22KOhm - Test point Works like a charm (you need to use 2.2KOhm to make the phone detect that you are using an external mic). Functionality is basic, but for checking noise on a power rail it's just what the doctor ordered. Well done guys!

The fact that I can change frequency, zoom in and out, and can view one or both of the channels is great. Also, it is cool I can change the colors as well

Really nice tool. Came in handy already a few times. Works on all my devices.

Only a VERY rare few test instrument apps give truly useful and accurate data. THIS APP IS ONE OF THEM !

Unfortunately my Samsung tablet does not have a USB Jack.

I'm an iOS developer; I applaud the software developers for releasing this app. It's simple and effective and it breathes new life into old gear. While I'm sure some people would like more complex features & user interface gimmicks, I'm quite happy with the $5 US price and the fact that it runs on old Android hardware. That gets it 5 stars right there. I ran it on my old Samsung Galaxy Tab - I haven't found a worthwhile use for this device since I bought the darn thing, until now. While it would be nice if all the dialogs fit on the screen (there are a LOT of options on some dialogs and it pushes the DONE button off the screen at times), the fact that I can scroll and still access everything keeps it functional. I plan to use this to teach my kids sound theory along with a homemade Arduino sound synthesizer and an Access Virus TI.

I needed to be able to use the mic jack to do ttl testing. This does not allow for it. Perhaps I misunderstood or read to much into the description. Without the usb adapter it is only good for picking up and plotting audio from the built in mic. PLEASE NOTE: This only tested this products ability to monitor TTL logic signals from a serial interface. No other functional testing was done. From: Andreas Rudolf Aug 6, 2013 Dear Mr Slaughter I am writing to you because of your review for the Android Google Play Store application "OsciPrime Oscilloscope". Not long ago, Google has made it possible for developers to publicly reply to user reviews. However, I would rather not reply to this review publicly. My suggestion is that you remove your comment. You can still keep the rating of course. However, it would be a nice thing to rethink your review. After all, it is technically not possible to measure TTL signals over an audio input line, and this is certainly not our fault, neither have we ever indicated or implied such a functionality. We are sorry if there has been any confusion with the product, the OsciPrime software and hardware are both completely open source and we try to ke

I have been using oscilloscopes for over 35years. And Digital scopes almost since they first came out. I fully expected this app to have a somewhat less than professional approach, but I was really surprised to see a display that compared quite well with professional equipment I had used before. Excellent app. I do so wish that the hardware portion were more affordable though.

This is well done software and is a real asset. Much better on tablet than phone, but improving.

Amazing Really nice tool. Came in handy already a few times. Works on all my devices.

Does not work as expected I needed to be able to use the mic jack to do ttl testing. This does not allow for it. Perhaps I misunderstood or read to much into the description.

Won't work on my Galaxy 10.1 Tablet Unfortunately my Samsung tablet does not have a USB Jack.
