Verdict

The call

The clearest difference is rating: USB Mobile Disk at 4.3 against Device Locator's 2.9. USB Mobile Disk also leads on in-app purchases (none vs 4) and price ($0.99 vs $3.99). Device Locator's advantage is ads (none vs shown) and update cadence (every 3 weeks vs every 3 months). On ratings volume, device support and iOS requirement there is nothing between them.
