The moon button at the left of the player's volume row sets 5 to 90 minutes, or End of Track. When time is up the music fades out over a few seconds and pauses, and the next Play comes back at the usual volume. End of Track stops with the next track cued, so Play carries on from there. - Up Next. Swipe a track right for Play Next or Add to Queue, or queue a whole selection at once. The list button at the right of the volume row opens Up Next: drag to reorder, swipe to remove, tap to jump ahead. The new order holds with gapless playback and crossfade too. - An EQ for each pair of headphones. Turn on "EQ for This Device" on the EQ screen, and that headphone or DAC gets its own curve, switched in whenever audio plays through it. Devices without one use the general EQ, and saved devices can be removed on the same screen. Wired 3.5 mm headphones are remembered by the adapter or DAC they plug into, since an analog jack doesn't tell the iPhone which headphones are on it. - Light appearance. Choose Dark, Light or System under Appearance in Settings. Light puts brass accents on a warm white ground and keeps text crisp in bright places; System follows the iPhone's own Dark Mode setting. Dark, the look so far, stays the default. On iPad, Settings' Language entry is now Language & Appearance and holds it. - Genre, estimated from the sound: Pop, Rock, Electronic, Hip-Hop & R&B, Jazz & Blues, Classical, Ambient or Folk & Country — shown only when the answer is clear, and left blank when it isn't. It appears in the track list and the info sheet, and the Library's Filter (formerly the Instrument button) can narrow by it. Everything is analysed on the device and the file's own genre tag is never changed. The library is analysed once more after the update. - Play with Siri. "Play fidelplayer" picks up where you left off and "Shuffle fidelplayer" shuffles the whole library. "Play (a folder or playlist) in fidelplayer" plays it in order, and "Shuffle (name) in fidelplayer" shuffles it. Favorites can be named the same way, and the same actions are in the Shortcuts app. "fidelplayer shuffle" and "Play fidelplayer on shuffle" shuffle too, and "Play music in fidelplayer" plays the whole library rather than a folder that happens to be called Music. - Sort tracks in the Library and in folders by name or by date added. The sort button above the track list (at the top of the screen inside a folder) sets the order and its direction — A to Z / Z to A, oldest or newest first. The choice applies to the Library and every folder, and is kept across launches. - Swipe a track left and an Info (i) button sits next to Delete. It shows the file name and location, size, format and codec, dates added and modified, sample rate, bit depth, channels, bitrate, and tags such as album artist, year, track number and composer. Improved - Deleting a track or a folder with a swipe now asks first. For a track of a CUE album kept in one file, it says that the whole file goes. - On iPad, importing with the + button while inside a folder puts the files in that folder. They used to land at the top of the Library. - On iPad, the folder (...) menu no longer repeats Import Files, which the + button above already offers. ### 1.8.1 — 2026-10-11 New - Sort tracks in the Library and in folders by name or by date added. The sort button above the track list (at the top of the screen inside a folder) sets the order and its direction — A to Z / Z to A, oldest or newest first. The choice applies to the Library and every folder, and is kept across launches. - Swipe a track left and an Info (i) button sits next to Delete. It shows the file name and location, size, format and codec, dates added and modified, sample rate, bit depth, channels, bitrate, and tags such as album artist, year, track number and composer. Improved - Deleting a track or a folder with a swipe now asks first. For a track of a CUE album kept in one file, it says that the whole file goes. - On iPad, importing with the + button while inside a folder puts the files in that folder. They used to land at the top of the Library. - On iPad, the folder (...) menu no longer repeats Import Files, which the + button above already offers. Fixed - On an iPad held upright, choosing New Folder in the Library showed the folder-name prompt and closed it at once. - On iPad, rotating between portrait and landscape with a folder open in the Library dropped you back at the top of the Library. - On iPad, importing a file from iCloud Drive could finish downloading, close the picker and still leave the file out of the Library. The copy now waits until the file is fully on the device, and a copy that comes across incomplete is reported as a failure. - Choosing a target rate in Settings that the output can't run at made upsampling look active when it wasn't. On the built-in speaker, fixed at 48 kHz, picking 192 kHz widened the spectrum to 96 kHz while the output stayed at 48 kHz. Changing the setting now checks the output too, and plays at the source rate when the target isn't supported. - The upsampling badge and the signal path now show whether upsampling is actually running, not whether the setting is on. Playback at the source rate shows no badge. ### 1.8.0 — 2026-10-06 New — CarPlay (Beta) - Connect to a CarPlay car and fidelplayer appears on the car screen. Pick music from four tabs — Folders, Playlists, Favorites, All Tracks — and control it from Now Playing. New — Personal Sound - Five tone controls: Bass, Warmth, Vocal Presence, Sibilance and Air. No EQ knowledge needed. Only the band you raise gets louder, the rest stays as it was, and a double-tap returns a slider to the centre. With every control centred, nothing is processed. - Per-ear hearing compensation, from the in-app hearing test (six frequencies per ear) or an audiogram imported from the Health app. Health data is read, never written. This is not a medical test. New — Spatial audio - Personalized Spatial Audio applies the ear scan from your iPhone's settings to headphone spatial audio (iOS 18 and later). - Head tracking keeps the sound in front of you as you turn your head, with AirPods (iOS 18 and later). - Virtual Space places the music in one of four computed rooms: Control Room, Living Room, Concert Hall and Cathedral, with an Amount control. New — Sound quality - Clip protection looks ahead and holds peaks under −1 dBTP only when processed audio would go over. Anything that stays under full scale passes bit for bit. - Volume normalization measures each file's loudness with EBU R128 (BS.1770-4) and levels it, in Auto, Track or Album mode. Results are kept, and in gapless playback the gain changes exactly at the track boundary. - High-quality upsampling. Turning upsampling on used to cut the top octave (−6.9 dB at 20 kHz, 44.1 → 96 kHz). It now uses the best converter available and stays flat to 21 kHz. If the output can't run at the target rate, the source rate is used. - Loudness compensation follows the ISO 226:2023 equal-loudness contours and tracks your listening level. - EQ Auto Headroom lowers the level by as much as the EQ boosts, so it doesn't clip. - Each EQ band can be a peak, low shelf or high shelf. AutoEQ shelf filters now import as shelves. - Crossfeed is now bs2b: bs2b Default, Chu Moy and Jan Meier, or custom cutoff and feed. New — Layout - Supports landscape mode. Improved - Harmonic Extension was redesigned. It used to act as a level-dependent treble shelf (+3.8 dB at 10 kHz at strength 0.5), and the amount of harmonics swung by nearly 60 dB with input level. It now adds only new harmonics to the untouched signal, at the same amount whatever the level. - 48 kHz-family DSD now plays converted to 96 kHz. - 16-bit FLAC export uses proper high-pass TPDF dither, and export goes through the high-quality upsampler and clip protection as well. - On loudspeakers, the headphone-only features (Crossfeed, HRTF binaural, Virtual Space) now switch off automatically, and an alert says what was turned off. This covers the built-in speaker, CarPlay, AirPlay, line out and HDMI. Your settings are kept and come back when headphones return. Bluetooth and USB DACs count as headphones. Fixed - Linear- and minimum-phase EQ drifted from the standard EQ in the bass; at 192 kHz, bands below 30 Hz came out at half strength. They now match within 0.1 dB at every rate from 44.1 to 192 kHz, and switching phase mode no longer changes the level. - The AutoEQ preamp was dropped in linear- and minimum-phase modes. - Switching between presets could make the sound break up. User presets now save and restore the preamp, and built-in presets return to the standard frequency layout. - Raising Bass in the tone controls left the bass where it was and turned the mids and treble down. The bass shelf has also moved to 150 Hz. - Large rooms in Virtual Space had a tail far too short (Cathedral 0.87 s, now 3.42 s). - The Bit-Perfect badge now appears on wired outputs only. Bluetooth, AirPlay, CarPlay and the speaker process audio again and show DIRECT. - Deleting the track that was playing from the library could crash the app. ### 1.6.0 — 2026-09-09 New — iPad layout - A standing sidebar in place of the tab bar. The four destinations — Player, Library, EQ, Settings — and the library's own sections — All Tracks, Favorites, Playlists, Folders — fit in one column, each with its count. - The mini player moved to the foot of the sidebar. It no longer floats over the list hiding the last row, and it has room for the elapsed and remaining times. - A now-playing inspector stands beside the library — artwork, track details, transport, and the Up Next queue, all visible while you are still choosing what to play. The queue no longer costs a trip to the player. - Settings is a category column beside the setting you are editing, instead of one form twenty sections deep. ### 1.5.1 — 2026-08-31 New — Mini player - A playback bar floats at the bottom of the library: artwork, title, artist, and previous / play-pause / next New — Lyrics - Shows lyrics stored in the file: FLAC (Vorbis LYRICS), MP3 (ID3 USLT, SYLT, TXXX), MP4 / M4A (©lyr) - Shown in place of the artwork. Button at the artwork's top right, or tap the artwork - Button appears only on tracks that have lyrics - Follows playback line by line when the lyrics carry timing - Reads a .lrc beside the track (song.flac ↔ song.lrc) - Import, move and delete carry the .lrc along - Precedence: a tag inside the file wins; .lrc only when the file has none - Handled on device. Nothing looked up or sent anywhere New — Waveform progress bar - Option to show the track's waveform as the progress bar (Settings ▸ Waveform progress bar) - Plain bar remains the default - File read once on first play, then cached - Bar height is the stretch's actual loudness (RMS) New — HFR (high-frequency reconstruction) - Detects each file's cutoff automatically (was fixed at 16 kHz) - Shows what it found (e.g. HFR 15.1k), on the player badge and the signal path - Switches itself off on full-band sources (HFR OFF) - Treble lift separated from HFR. Two switches in Settings: · HFR — fills the empty band. On or off, always fully applied · Treble Lift — 7 kHz shelf up to +9 dB. Amount set here Bug fixes - The mini player vanished on stepping into a library folder or a playlist. ## Apps similar to fidelplayer | App | Rating | Price | Category | | --- | --- | --- | --- | | [Tonar: FLAC Hi-Res Player](https://appshunter.io/ios/app/tonar-flac-hi-res-player/id6791282669) | 3.8 (5) | Free | Music | | [PurePlayer Hi-Res](https://appshunter.io/ios/app/pureplayer-hi-res/id6756600304) | 4.0 (2) | Free | Music | | [Vivace: Lossless FLAC Player](https://appshunter.io/ios/app/vivace-lossless-flac-player/id6778066358) | 4.8 (4) | Free | Music | | [lumina - HiFi player](https://appshunter.io/ios/app/lumina-hifi-player/id6756905071) | 5.0 (1) | Free | Music | | [PureBit: Hi-Res Music Player](https://appshunter.io/ios/app/purebit-hi-res-music-player/id6770176470) | 5.0 (8) | Free | Music | | [Nyquist Player](https://appshunter.io/ios/app/nyquist-player/id6783843925) | 4.0 (1) | Free | Music | ## More apps by JINHONG KIM - [단모음키보드 럭럭고](https://appshunter.io/ios/app/id6759483875) - [Binaural Beats: Focus & Sleep](https://appshunter.io/ios/app/binaural-beats-focus-and-sleep/id6775225093) - [CardVault: Biz Card Scanner](https://appshunter.io/ios/app/cardvault-biz-card-scanner/id6776257121) - [EasyScan: Doc Scan & Share](https://appshunter.io/ios/app/easyscan-doc-scan-and-share/id6779710866) - [Sticko: Notes & Widget](https://appshunter.io/ios/app/sticko-notes-and-widget/id6816661887) All apps by JINHONG KIM: https://appshunter.io/developer/1878939629 ## Related topics [hi-res](https://appshunter.io/ios/topics/hi-res) · [prv audio](https://appshunter.io/ios/topics/prv-audio) · [weezer audio bliss](https://appshunter.io/ios/topics/weezer-audio-bliss) · [polk audio](https://appshunter.io/ios/topics/polk-audio) · [vplayer hifi](https://appshunter.io/ios/topics/vplayer-hifi) · [upsampler](https://appshunter.io/ios/topics/upsampler) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
