Choose storage limits and keep favourites offline. Data saver asks your Plex server to convert audio to your chosen bitrate, with separate Wi-Fi and cellular preferences and measured transferred-data totals.

Larger displays have room for the player and queue side by side. iPhone Duo adapts from a compact cover-screen player to a stacked portrait layout and a side-by-side player and queue when opened in landscape.

Verdict
The clearest difference is in-app purchases: JellyBox Player at none against Flex's 3. JellyBox Player also leads on update cadence (every 5 days vs every 2 months) and ratings volume (7 vs 1). Flex's advantage is rating (5.0 vs 4.7). On price, ads, device support and iOS requirement there is nothing between them.
