Download:
Cost: Free (Free), Hiya Premium ($2.99/month (USD))
Hiya is a popular spam phone calls app praised for its initially high accuracy in identifying and blocking unwanted calls—users report a previous 95% success rate. However, recent updates have introduced a paywall for caller ID information and reduced accuracy to around 80%, leading to missed important calls and user frustration. While its spam-blocking capabilities remain functional, the aggressive push for a premium subscription, including multiple pop-up reminders, has soured the experience for long-time users who appreciated its formerly free features. The shift from a beloved free app to a paid service, even with a one-time payment option being preferred, leaves many questioning its value proposition.

Key Features:
- Identifies and blocks unwanted calls.
- Provides caller ID for unknown numbers.
- Offers voicemail transcriptions for convenience.
