By Ear PRO vs OverDrive Chords & Stems

"How do they play that part?" — this app answers it. Every musician hits the same wall sooner or later: working a song out by ear. A song with no sheet music. A phrase you love. That intro. By Ear PRO takes that wall down with four tools. 1. A head start on the chords Import a track and you get a first reading of the chord progression. Your ears still decide — you just don't have to start from nothing. 2. Slow playback that keeps the pitch Play a fast phrase slowly without it dropping in pitch. Combine it with AB repeat and you can loop the hard part as long as you like. 3. Work it out while you watch the piano roll The chords sit on a piano roll in front of you. See it, hear it, and correct it until it matches what you heard. 4. Start from a blank roll and write it yourself Enter notes at your own pace from nothing at all. Insert chords as you go and build the structure while you work. ABOUT THE PRO PLAN A one-time purchase with a permanent licence. Buy it once and there is nothing more to pay.

Turn any song into something you can play along to: chords detected for you, four stems split out, any phrase looped at half speed without changing pitch. All of it runs on your iPhone. No audio is ever uploaded. That's on your own. With a band, everyone shares one chart and one playhead. ■ Chord detection, stems and phrase looping Import a song and get its chart in about ten seconds, right on the device; split it into drums, bass, other and vocals whenever you need to, then loop one phrase as long as you like: 0.5x-1.5x without changing pitch, solo or mute any stem. Paste in the lyrics and the phone listens to the song and puts each line on its bars (needs iOS 26). ■ Backing tracks for practising alone Drums, bass and guitar follow your chart. Nine styles (pop, rock, ballad, country, shuffle blues, reggae, funk, jazz swing, bossa nova), each with two alternate arrangements, and each part can be muted. The harmony comes from your chart: what you write is what you hear. ■ Video practice Import a lesson video from your phone, mark in and out, loop those few seconds full screen, slowed down if you like. ■ Number-system charts No staves, no tabs, just the numbers (1 5 6 4). Change the key and every chord on every screen follows. ■ The chart moves by itself, so your hands stay on the instrument Hit play and the chart advances at the song's BPM: which beat you're on, what this bar is, what comes next. Section changes come with a countdown. ■ Songs are written in sections Intro, verse, chorus, bridge. Each section carries its own progression and repeat count: you are in the chorus, it goes 1 5 4 6, pass 2 of 3. Singers can switch to the lyrics view and get prompted line by line. A full chart can also live on your Home Screen: pick a song in Settings and add the widget. ■ On iPad, it's the music stand The rehearsal view lays out the whole song like paper: one panel per section, four bars to a row, lit up to wherever the band is. Put it on a stand and play. ■ Local network sync, no internet needed One person hosts, everyone else types a four-digit room code. The leader starts, changes tempo, jumps sections, locks a loop, and every playhead moves together. No server, no account, no sign-in. ■ Rehearsal recording Plug in your mixer or audio interface and record the whole session. Every time someone hits play it becomes a take; keep the ones worth keeping and export m4a. ■ Full-song overview and PDF export What you see is what you print: the same chart, the same page. ■ Subscription OverDrive Pro is an auto-renewable subscription, 1 month. The price for your storefront is shown in the App Store, and in the app, before you confirm. It unlocks the AI transcriber, hosting a room and PDF export. Everything else is free with no time limit, including on-device stem separation, looping, video practice, and joining someone else's room, and for the first 30 days after install those three are free as well. Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period.
