A Bug for fixing and suggestion

• When adding songs (putting songs in the dedicated “Music” folder in the app directory), the app seems to stop loading new songs—even after refreshing—past ~150 songs added into that folder. It is either this, or that at the ~150 mark, if you delete a song and then attempt to re-add it through the Music Folder, it will not appear automatically, forcing you to use the “Open Files” button strangely.

You should add a way to edit the file’s tags or lyrics inside of the app.

Response from developer

Hi if you have any issues you can make one on github. Thanks for the kind comment.

One of the best offline music player

My main problem is that you have to have your downloaded music saved to the cloud because every time when the app updates, all songs would stop working

Best at what it is

I was searching for a music player to play my music locally offline since I plan on moving away from music subscriptions to owning my own content. I was genuinely surprised that the entire app store didn’t have a single ‘offline music player’ that worked without paying anyone money. This is the only app that does what it says it does, it’s also extremely fast at indexing content, I was able to import hundreds of high quality music within seconds, does a good job at fetching metadata online as well. Really good work to the devs! 💪

Excellent music player

Great app, I think is better then vcl player

‼️ Bugs for fixing

When large loads of songs are applied (120+ files), the app can begin to break. It may clear your custom playlists or remove all of your songs.

Наконец на iPhone появился настолько плеер

The nearly perfectly open-source & zero telemetry music player I've waited YEARS for!

This app is what I've been waiting for, for years... I have been using VLC and other music apps that don't collect data and are preferably open source. This is it. This has THE potential to be the #1 local music player in the App Store with one of the cleanest looking user interfaces I've seen.

However, there are a few glaring issues keep me from fully switching over. Keeping in mind the app's early development, here are a few positives and negatives.

Positives:
- Open-source 🙏
- Supports MP3, FLAC, OPUS (buggy) & WAV.
- Does not collect data or use telemetry.
- Very nice UI (not so good UX).
- Allows users to import a custom GraphicEQ.
- Importing local music is easy and allows users to import songs from different folder locations.
- iCloud integration (not useful personally but a pro nonetheless).

Negatives:
- Adding/Appending to Queue is barely barely implemented and quite rudimentary.
- OPUS files display blank metadata.
- The option "Remove from library only" off by default. An unsuspecting user may unintentionally delete all of their local music files.
- When importing large numbers of music files (~2,000+) the app crashes. Although this may be due to the files app itself.
- Does not allow M3U/M3U8 playlist importing or exporting.
- Created playlists are only available in JSON format.

Note to the Lead Developer (clquwu):
Overall this is a wonderful app and I have been following its development closely. I'd like to make a kind suggestion that the queue, playlists and importing be prioritized as those are the only issues preventing my full switch over. In time of course. Thank you for taking initiative and creating something like this for little to nothing in your valuable time on this earth. 🙂

Love the feedback unfortunatly, the format M3U and M3U8 works with path that is probably from your windows / desktop app anyway so cross referencing that is impossible. Will see what i can do for the crash on huge loads.

Зависает

Приложение удобное, но есть пара замечаний. После последнего обновления периодически зависает и сбрасывает песню при прослушивании, либо пропускает песни при выборе песни, то есть он даже не включает ее, а просто включает следующую. С файлами проблем нет, они проигрываются на телефоне без ошибок, в самом плеере тоже через раз проигрываются. Очень часто зависает сам интерфейс, не реагирует на нажатия. Также при нажатии на сердечко не всегда добавляет песню в избранное. Также порой при сворачивании приложения и повторном разворачивании звук становится громче, притом что звук системы телефона не меняется. И хотелось бы видеть возможность редактировать имя песни, а то порой песни добавляются в виде символов

If you have any issues make an issue on the github repository.

Helpp

Great app!! I liked everything at the beginning, everything is comfortable and pleasant. But I've encountered a problem, now, when I go in, the first ten seconds everything is fine, and then everything just freezes. The app doesn't respond to touch or anything I'm very very sad. P.S. (English is not my first language, translated through a translator)

Nostalgic

I love the app and the look of it. Using this app along with others to create my music library is putting me back in the days of LimeWire and ripping CD’s and I dig it. The ONLY thing I would ask for is a volume slider in app, I don’t know. Just cause 🤷🏻‍♂️ for people wanting to edit metadata, you should use Evertag, pretty simple to use and find with just a search 👀

Love the app and I appreciate it and its creators existence. Can’t wait to see if and what it develops into!

It’s good but I have issues

Overall it’s a very good player. I just have issues with removing music. Seems like it’s does not want to update the database. I’ll continue using Foobar2000 for now. Thanks.

Amazing app and UI

I love this music player due to it having a very comfortable and easy to navigate interface it also gives detailed summary about artists and auto imports audio

All I wanted.

Im not sure why this is rated so poorly. It does exactly what I’ve been looking for: play music files in a convenient manner, and it had no obtrusive and annoying ads…

To be fair, I don’t use many features like playlists and I’ve only used it for a small time so I can’t say how good the shuffle feature works. Still, it’s better than the most popular app.

Absolutely lovely

All I did was convert music video links from YouTube into mp3 files then sent them to the cosmos app. Zero ads ever, zero problems. Just don’t permeantly delete those files from your file app or else the music will all disappear because they’ve been deleted 😭learned that the hard way, which was 1000% on my inexperience. The app is pleasant to use with a friendly user interface

Could be great but misses the mark

Having to import and make playlists is clumsy as hell and needs to be automated. Shuffle is on permanently no matter what buttons are pressed or settings change. The toggle for shuffle is purely decorative and does nothing. It’s a great player if not for that. Trying to find something better.

Needs improvements

This is not a bad app, but as a regular user I suffer from using it, because it doesn’t follow UX best practices and it has a lot of bugs. I can tell this is a developing app, and it needs more time so the developers can make it perfect.

Response from developer

If you have issues report it if you want it to work on the ux i would love too. Everything is on the github.

Love

Love this i was worried i wouldn't be able to listen to my library because itunes just didnt like the formats i used but this app lets me listen to it.nice beautiful app that does what it's supposed to

Amazing job.

What a beauty. Lovely app at what it does. Some suggestions if you want se feedback:
1. if you search a song, you can’t long press to get options such as adding it to a playlist. You have to play the song first or look it up manually in the all songs sections. Same issue in the queue section.
2. You cannot create a queue/run songs of just the search results. Like some files can have the name of the artist alone and it kinda creates a playlist of that artist songs alone.
3. When you open any playlist, the last song is hidden behind the current playing song, which doesn’t look good.
4. Custom playlist order rather than alphabetical. (The playlists not the songs inside which you can sort manually which is such an underrated feature)
5. A nifty feature would be to allow us to sort songs in the all songs section ‘not in a playlist’. Like in the apple photos app. So if you like to sort all your songs in playlists, this way you can see which ones are left to do.
6. Allow us to remove songs from the queue. This is a big one.
