SampleFlow is a native iPhone app for preparing non-clinical blind-comparison sessions (coffee, tea, fragrance, materials, packaging, prototypes). It has no account, no login, no in-app purchase, no ads, and no subscription. The first screen is a local welcome / operator-setup page bundled in the app. Please complete it before reviewing the product: Enter any operator name, for example: Reviewer Tap Save. The page reloads so the saved name is applied. Tap Open to enter the native SampleFlow workspace. All project data, plans, blind codes, and exports stay on device. Recommended review path after Open: On the Desk / Projects tab, open the bundled Coffee Tasting example (or create a new project). Open Sequence Plan to see participant-specific blind-code orders. Open Balance Check to inspect the sample-by-position matrix. Open Export Center to preview participant cards and CSV / PDF outputs, then use the system share sheet if needed. Duplicate the example or create a project to test Cyclic, Williams, and Shuffle methods. SampleFlow is a preparation tool only. It is not intended for clinical trials, medical decisions, or regulated research, and it does not claim statistical validity.

Verdict
The clearest difference is in-app purchases: SampleFlow at none against Compass's 4. Compass's advantage is iOS requirement (13.0 vs 15.0). On price, ads and device support there is nothing between them.
