Atomic Clock (Gorgy Timing)
The App DNA
What makes this app unique?
Users hire the app to synchronize legacy atomic watches in signal-dead zones and manage daily routines without the bloat of general-purpose assistants.
For Android users seeking a standard desk clock utility and niche users of radio-controlled timepieces requiring manual signal calibration.
What does it look like?
Key features
Generates longwave time signals via device speaker for manual calibration of radio-controlled clocks.
Standard utility for recurring alarms, countdown timers, and stopwatch functionality.
Syncs alarms and timers to wearable devices via tiles and complications.
How much does it cost?
Monetization is split between a paid tool for niche radio-calibration and a free utility model for Android desk clock users.
Velocity
Dormant developmentopaqueShow more...
The development momentum is classified as zombie status due to a lack of activity for several years. The most recent release occurred in April 2026, but the preceding history shows a significant gap between 2022 and 2026, with no meaningful feature development identified. The release history indicates a long-term pattern of minor bug fixes rather than active product evolution. There is no evidence of live operations or ongoing feature support.

Competitive landscape for Clock Wave
How's the Utilities market?
Clock Wave occupies a dual-utility space, holding a niche position in horology tools while competing as a general alarm app on Android. The #89 Paid rank in its category reflects a specialized, low-volume market compared to the high-frequency usage of the free Android desk clock utility.
Read the market outlookThe rivals identified
By CompuLab, Markus Gömmel
Both apps target users requiring precise timekeeping, with Clock Wave providing audio-based radio signal simulation for legacy hardware and Atomic Clock offering NTP-based synchronization for professional broadcast environments.
- Atomic Clock provides a professional broadcast-style interface, while Clock Wave focuses on functional radio-signal transmission for hardware.
- Atomic Clock relies on internet-based NTP servers, whereas Clock Wave enables offline synchronization for atomic watches via audio signals.

Key takeaways for Clock Wave
Where is it heading?
The utility-alarm market is consolidating around apps that offer aggressive, mission-based wake-up features, leaving Clock Wave exposed due to its recent stability regressions. The PM must shift from UI-centric updates to core reliability to prevent the current sentiment decline from permanently eroding the user base.
- Alarm reliability regressions in the latest update cause missed wake-ups, which directly drives the current rating decline on Android.
- Recent updates focused on Material 3 design, but the lack of core utility expansion leaves the app exposed to feature-rich competitors.
The SWOT
- Audio-based signal transmission provides a hardware-agnostic solution for legacy timekeeping
- Wear OS integration increases switching costs for Android users
- Expansion of signal station coverage to underserved regions
- Integration of light mode to improve accessibility for daily users

Since the last report: The app expanded its utility scope to include general alarm management and Wear OS support, but introduced critical reliability regressions that negatively impact user sentiment.
Bottom line
Clock Wave maintains a strong niche in radio-sync utility, but recent Android updates have triggered alarm reliability regressions that threaten retention, so the PM must prioritize stability fixes over new UI features to prevent churn.
