Competitive Products
1. APRSdroid: Integrates mapping and messaging but lacks Ham Clock’s transmission reminders and note-sharing simplicity.
2. Clock+ Pro: Offers multi-timezone tracking but targets business users, missing ham-specific compliance features.
3. SOTA Spotter: Specializes in summit activations but requires internet connectivity, unlike Ham Clock’s offline reliability.
Market Performance
While niche, Ham Clock holds a 4.3/5 rating on amateur radio forums, praised for its reliability during field operations. Limited mainstream visibility keeps downloads modest (est. 10k+ on Play Store), but loyal users highlight its unmatched focus on regulatory adherence and privacy.
