Folder Looper is a focused audio player for people who keep their audio organized in folders. Choose a folder from the Files app and Folder Looper continuously plays the supported audio files inside, without requiring a music library, playlist setup, or account. It is built for musicians, worship teams, performers, teachers, language learners, audiobook listeners, and anyone who wants quick access to organized audio files in iCloud Drive or other Files locations. Version 2.0 adds a new Practice mode alongside the folder player. Move the current song into Practice, or choose a single audio file, then slow it down, speed it up, transpose it, repeat it, and view detected key and tempo details as a starting point for rehearsal. Folder Looper can also display embedded song artwork when available, show Now Playing information, support background playback, and let you browse or reshuffle the current play order at any time. Features: • Play audio files directly from folders in the Files app • Supports MP3, WAV, AAC, AIF, AIFF, CAF, and M4A formats • Continuous playback through all supported files in a folder • Optional shuffle mode • Browse the play order, jump to any song, and reshuffle anytime • Background audio and remote playback controls • Displays embedded song artwork when available • Shows current song, folder, playback time, song count, key, and tempo details • Remembers your selected folder between app launches • Smart filename sorting for numbered tracks • Works with iCloud Drive and other Files-accessible locations Practice Features: • Choose a single song for focused practice • Bring the current Player song into Practice • Detect key and tempo for supported audio files • Transpose from one key to another • Adjust playback speed from 50% to 150% • Repeat the practice song continuously • Reset detected values, key changes, and speed changes without removing the song Key and tempo detection are helpful estimates based on the audio signal.

Rondio is a player for the music files already on your iPhone and iPad. Just register a folder you can see in the Files app, and songs you ripped from CDs and songs you bought all play as one library, no matter where they are stored. And shuffle actually shuffles. One pass plays every track exactly once, and the same artist never comes up twice in a row. Note: playing multiple folders as one library, and the even shuffle, are both Premium features. Free to try for 14 days. ■ Importing is just picking a folder • Register any location visible in the Files app, on the device or in the cloud (songs kept in the cloud are downloaded to the device before playing). • Pick one parent folder and every song beneath it comes in. • Up to 10 folders can be registered. Registering itself is free. • Track information is read in the background, and songs appear in the list as they are read. There is no need to wait for it to finish. ■ No duplicate copies • Rondio reads your original files instead of making copies inside the app. • You never hold the same song twice, so none of your storage is wasted. • Rename or reorganize your files and your play counts and favorites follow along. ■ Your Music app songs, in the same library • Songs in the device's Music app are handled just like a registered folder. • Ripped songs and purchased songs mix freely, without you having to think about where they came from. • Please note: songs streamed from Apple Music (subscription songs) cannot be played, as they are protected. Purchased downloads and songs you imported yourself are supported. ■ Supported formats MP3 / M4A (AAC, ALAC) / FLAC / WAV / AIFF ■ Background listening • Background playback and Lock Screen controls are supported. • Choose what to play from all songs, a playlist, an album, an artist, a genre, or a decade. • For each of those, choose in the moment whether to play in order or shuffled. (Rondio Shuffle — the one that doesn't clump — is Premium.) • Favorites, playlists, and search are supported. • Dark Mode is supported. • On iPad, both orientations and multitasking are supported. ■ Rondio Premium (one-time purchase) Rondio is a one-time purchase. A single payment unlocks the following two things. There is no monthly or yearly subscription. [1] Rondio Shuffle (no clumping, no repeats) • The moment you press shuffle, the order of every track in the selected range is decided in advance. One pass plays every track exactly once. • Tracks you haven't heard yet come up sooner. • The same artist never plays twice in a row. • Your favorites are spread evenly through the pass. • You can also shuffle by album, which shuffles only the album order and keeps each album's track order intact. [2] Everything together in one library • Registered folders and Music app songs play together, across every location. • Albums, artists, and playlists all work across your entire collection at once. ■ What you can do without buying The player itself works without limits, whether or not you buy. • Play one of your registered folders, or the songs in the Music app. You can switch which folder plays at any time from Settings. • Playback, lists, search, favorites, playlists, and background playback all work as they are. There is no song limit, no advertising, and no time limit. ■ Pricing • A 14-day trial comes before any purchase. Every feature is available to try, exactly as it is. • When the trial ends, everything described above stays available with no time limit. Imported songs, favorites, and playlists are never deleted. Only the number of folders you can play from is limited to one. • If you like it, one payment unlocks every feature, with no expiration. • After changing devices or reinstalling, "Restore Purchases" brings it back. ■ Privacy No account is required. Track information and play counts stay on your device and are never sent anywhere. There is no advertising of any kind.

Verdict
The clearest difference is in-app purchases: Folder Looper at none against Rondio's 1. Rondio's advantage is update cadence (every 4 days vs monthly). On price, ads, device support and iOS requirement there is nothing between them.
