"I use this for analog, and audio measurements. Attach an Apple USB adapter and a $40 stereo A-D converter available online, and my iPad is like a $300 O'Scope." -thymeout- Oscilloscope app is great for analyzing audio range signals, or learning oscilloscope measurement basics. The interface includes many standard oscilloscope controls, such as: triggering, time and voltage per division, signal measurement cursors, and more. The app incorporates a signal (function) generator capable of generating sine, square, triangle, and sawtooth waveforms of up to 22 KHz. Calibration to an external reference signal is supported, guaranteeing the accuracy of measurements. Input can be acquired via the built-in microphone or an external mic/probe connected to the headset connector. For best results, use an external audio interface connected to your device dock. This allows for standard audio equipment to be connected, as well as for dual channel input. Oscilloscope probes also be connected (using a BNC connector). When feeding external signals via probes, you should take care not to exceed 1V AC voltage. Currently iDevices support only AC input.

Verdict
The clearest difference is price: Jam Looper at Free against Oscilloscope's $19.99. Jam Looper also leads on ratings volume (2.4K vs 19) and rating (4.4 vs 4.1). Oscilloscope's advantage is in-app purchases (none vs 8) and ads (none vs shown). On device support and iOS requirement there is nothing between them.

Jam Looper is free to download; Oscilloscope costs $19.99 up front. Jam Looper sells 8 in-app purchases, starting at $3.99 per 7 days. Oscilloscope asks for nothing beyond the download.
Jam Looper holds the better App Store score, 4.4 against 4.1. That said, the two scores are not equally well evidenced: Jam Looper has 2.4K ratings behind it against 19, so its average is the more settled of the two. Written reviews complicate that: 72% of Oscilloscope's written reviews are positive against 52% of Jam Looper's, so the app with the better star average is not the one people write more warmly about.
Oscilloscope ships an update every 8 months, Jam Looper every 3 months. The most recent releases landed on October 11, 2026 and October 15, 2026 respectively.
