# Discord4 vs JMP Pro

The clearest difference is review sentiment: JMP Pro at 100% against Discord4's 61%. JMP Pro also leads on rating (5.0 vs 4.7). Discord4's advantage is price ($3.99 vs $9.99) and update cadence (every 14 months vs every 50 months). On ads, in-app purchases, monetization model and device support there is nothing between them.
