Questions
Everything worth knowing before you start charting.
PocketCharter is built for making Clone Hero-compatible charts on iPhone. These answers cover compatibility, exports, audio, AI tempo tools, storage, privacy, and App Store basics.
What is PocketCharter?
PocketCharter is an iPhone chart editor for creating playable Clone Hero chart folders. You import your own audio, place notes on a five-lane fretboard, edit timing and tempo, then export a folder that can be transferred to Clone Hero.
Does PocketCharter include songs or copyrighted music?
No. PocketCharter does not include songs, stems, charts, or copyrighted music. You bring your own audio and are responsible for using files you have the right to use. The app is a creation tool, not a music library.
Can I import an existing .chart file?
Yes. PocketCharter can import existing .chart files so you can view or continue editing a chart on your phone. Imported chart data is converted into PocketCharter projects for editing and export.
Does PocketCharter support multiple difficulties?
Yes. PocketCharter supports multiple guitar difficulties so you can create charts for different skill levels. The editor is currently focused on guitar charting rather than full multi-instrument authoring.
Is the AI BPM detection guaranteed to be perfect?
No automatic beat detector is perfect for every song. It is best treated as a strong starting point, especially for songs with live drummers, tempo drift, unusual meters, quiet intros, or heavy syncopation. PocketCharter gives you manual editing tools so you can correct the tempo map before charting seriously.
What is the Tempo Editor for?
The Tempo Editor is a focused waveform view for checking and adjusting the beat grid. You can re-detect tempo, add BPM points, change point values, inspect the waveform, and choose whether to keep or discard edits when leaving the editor.
What happens if iCloud has an older project copy?
PocketCharter compares local and iCloud project timestamps and prefers the newest copy. If it needs to replace an older copy, it keeps a backup of the older project folder where possible.
Why does PocketCharter ask for photo library access?
Photo library access is used only when you choose album artwork for a chart. PocketCharter uses the image you select for that project's artwork and does not scan your photo library for unrelated images.
Can I use a guitar controller?
PocketCharter currently supports the CRKD Les Paul guitar controller. Other controllers are not officially supported yet, so touch editing remains the reliable fallback for all users.
How do purchases and refunds work?
Purchases are handled by Apple through the App Store. If you need a refund, use Apple's official App Store refund process. PocketCharter support can help with app issues, but App Store billing decisions are handled by Apple.
Is PocketCharter affiliated with Clone Hero?
No. PocketCharter is an independent editor. It is designed to export files that Clone Hero can read, but it is not made by, endorsed by, sponsored by, or officially connected to Clone Hero.
What does PocketCharter export?
PocketCharter exports a Clone Hero-ready zip containing the chart and song metadata, including files such as notes.chart, song.ini, album artwork when available, and your imported audio.
Which note types are supported?
PocketCharter supports normal notes, HOPO notes, tap notes, force strum notes, open notes, sustains, and star power sections. The export maps these to the Clone Hero chart events expected by the game.
How does dynamic BPM mapping work?
PocketCharter can analyze your imported audio and create a tempo map with BPM changes and a detected time signature. The Tempo Editor shows the waveform and tempo curve so you can inspect the result, adjust points, and fine-tune the grid manually.
Does AI tempo detection upload my audio?
No. PocketCharter's BPM and tempo detection runs on-device using the app's bundled model. Your project is not uploaded to a PocketCharter server for tempo detection.
Where are projects saved?
Projects are saved on your device. When iCloud is available for your Apple account, PocketCharter can also store projects in your private iCloud container so work can be backed up and synced through Apple's iCloud system.
Does PocketCharter track me or show ads?
No. PocketCharter does not include ads, third-party analytics, or tracking. See the Privacy Policy for the full breakdown of storage, iCloud, optional song lookup, and support contact information.
What does song identification do?
Song identification can help fill metadata such as title, artist, album, and artwork. If you use it, PocketCharter uses Apple services such as ShazamKit and iTunes Search. It is optional and is not required for charting or exporting.
How do I move a chart to Clone Hero?
Export the project from PocketCharter, transfer the zip to your computer, extract it into your Clone Hero songs folder, then scan songs in Clone Hero. The exported folder is structured for that workflow.
How do I report a bug or request a feature?
Email support with your device model, iOS version, PocketCharter version, what you expected to happen, and what actually happened. Screenshots or a short screen recording are especially helpful for editor, tempo, export, or iCloud issues.
