What it does
Whoscall is a utility app that provides caller identification and spam blocking capabilities. It maintains a database of numbers to alert users to potential telemarketers, scams, or business calls before they pick up. Users can also manually search numbers or URLs to check for malicious intent and report new spam to help the community.
Where it shines
The app excels in guiding users through technically difficult setups. At 00:42, it uses an embedded video tutorial to demonstrate exactly how to enable necessary extensions in the iOS settings. Later, at 02:57, it uses a similar visual guide to help users set up an iOS Shortcut for automatic database updates. This visual hand-holding is crucial for an app that relies heavily on OS-level integrations.
UX highlights
- The initial onboarding animation (00:03) effectively demonstrates the app's core value—blocking unwanted calls—before asking the user to log in.
- The use of an embedded video (00:42) to explain iOS settings configuration is a brilliant friction-reducer.
- Gamification is used effectively at 04:02, rewarding users with a badge and celebratory animation for reporting a spam number, encouraging continued engagement.
- The manual number lookup tool (04:47) provides clear, actionable results with straightforward 'Call' or 'Block' options.
- The database update process (02:24) uses a large, clear progress indicator to communicate system status effectively.
Monetization & growth
The paywall appears shortly after onboarding (01:17) and utilizes a tabbed design to present multiple subscription tiers (Individual, Duo, Family). It clearly outlines the premium features, emphasizing automatic database updates and an ad-free experience. A 7-day free trial is prominently offered to lower the barrier to entry.
Who it’s for
This app is built for individuals who frequently receive spam calls or text messages and want proactive protection. It appeals to users looking for a set-it-and-forget-it solution for maintaining a quiet, secure phone environment.
Notes & opportunities
The app relies heavily on the user leaving the application to configure iOS settings, which is unavoidable but risky. While the video tutorials are excellent, ensuring users return to the app after navigating away remains a challenge. Additionally, the manual database update process (02:24) feels slightly lengthy and could benefit from more engaging visual feedback while the user waits.
