OnPitch is a karaoke practice tool that displays a song's melody as notes and your sung pitch as a line over them. The official description combines song analysis, live feedback, exercises and recorded takes. Its intended audience is someone who wants to inspect pitch while practising rather than only sing along to a backing track.
This First look is based on the App Store listing. We have not analysed a song, recorded singing or measured pitch detection. The interface may supply useful feedback, but a visual line and score do not establish vocal health, complete musical accuracy or the quality of an entire performance.
Based on official store information. We have not tested this app hands-on.
What it does
The described input options are an audio or video file from Files, or a song you own in the Music library. The developer says OnPitch separates vocals, finds the melody and aligns lyrics. That is a processing claim, not a guarantee that every arrangement or recording produces a perfect transcription. Check the source material and any relevant access restrictions.
During recording, your pitch is drawn over the notes and coloured according to closeness. Points, accuracy and a multiplier provide game-like feedback. These can make a repeated passage easier to compare, while the meaning depends on the correctness of the extracted reference and what the app actually measures.
Practice controls include turning a section into a looping piano exercise, restoring original vocals for difficult passages and changing key. Detected notes can be hidden if they are wrong, and lyrics can be shifted in time. Those correction controls are important because they acknowledge that automatic analysis may need adjustment before it becomes a useful target.
Warm-ups include scales, arpeggios and sustained notes, with the option to create exercises on a piano grid. Repeated laps receive scores. A practical first session would choose a comfortable, short passage, inspect the reference notes and compare a few attempts without forcing the voice to match an unsuitable range.
Recorded takes are separate tracks whose volume and timing can be adjusted. The listing describes downloading the voice or a full mix and creating a karaoke video with lyrics over music. Past attempts are saved for comparison over the notes. This connects immediate feedback with a record you can listen to again.
Before you install
Pitch is only one part of singing. Timing, phrasing, diction, breath and expressive choices may not be represented by a closeness score. Do not treat a high number as proof of a complete performance or a low number as a diagnosis. We have not established the scoring method or its sensitivity to different voices.
The reference melody also needs review. Dense arrangements, backing vocals or instrumental passages can complicate automatic extraction. Use the controls for incorrect notes and lyric timing when needed, and compare a familiar section with the original recording. A plausible-looking line is not enough to establish accuracy.
Choose exercises that are comfortable for your voice. Key adjustment can help fit a passage, but the app's ability to transpose does not determine a safe training routine. Persistent discomfort is a reason to stop and seek appropriate guidance rather than chase a higher score.
Files and recording rights are another consideration. Owning access to a song does not automatically establish permission to publish a karaoke video or distribute a mix containing it. Review the rights applicable to your actual project before sharing. The source lists export capabilities, not blanket music licences.
We have not tested microphone latency, background-noise handling, separation quality or the precision of alignment controls. Check the actual device and listening setup, and review the saved audio rather than relying exclusively on the live display.
Price and access
The linked US App Store listing shows a free download. The retained description does not provide a full pricing schedule or clearly define any paid feature limits. Confirm the live storefront and purchasing screens before assuming all processing and exports are unrestricted. Compatible device requirements and permission to use the source music remain separate from the installer price.
Our take
The useful idea is turning a hard-to-hear pitch difference into something visible and repeatable. Section loops, a piano reference and past-take overlays could help focus a practice session, provided the extracted melody is checked and the score stays in perspective. The manual correction controls are particularly relevant to that workflow.
Start with a familiar passage and listen to each attempt as well as looking at it. Ask whether the feedback helps you notice a specific issue and whether the next attempt sounds more controlled, not simply whether the total rises. Keep practice comfortable and short enough to remain attentive.
We have not assessed training outcomes, accuracy or recording quality. Our take is a source-based introduction to a pitch-focused practice tool, with reference quality, rights and sensible vocal judgment essential to using its feedback well.
For a first comparison, keep microphone distance and playback arrangement consistent. Changes in the recording setup can affect what the app hears, making two attempts harder to compare. We have not measured the effect on this particular detector.
