Waldo allows mobile developers, designers, and product managers to record and monitor user flows. It tests those flows with every new build and reveals any UX differences.
Waldo works with Android and iOS (but this submission is specifically for the Android beta).
Compose private notes, optionally share them with others and still stay in control of who can access your data. All while having an excellent offline-first experience on all platforms.
