Verdict

The call

The clearest difference is ads: AirDisk Pro at none against USB Disk's shown. AirDisk Pro also leads on update cadence (every 8 days vs every 2 months) and chart position (#157 vs unranked). USB Disk's advantage is price ($0.99 vs $1.99). On rating, review sentiment, in-app purchases and monetization model there is nothing between them.
