Timegrapher X analyzes the ticking sound of a mechanical watch to measure its accuracy rate, beat error, and amplitude. The app is specifically optimized to work with the Apple EarPods' headset microphone. Ideally, the headset microphone and the watch crown should be slightly pressed together, as this greatly improves the level of detail and diagram quality. The better the contact, the stronger the signal. https://timegrapher.app/ Timegrapher X consists of two separate modules (tabs): The "INSTANT" module shows how the watch is behaving in the short term, or "right now". It is very similar to a traditional timegrapher device, with the added benefits of a real-time waveform display and a high-detail diagram display. The "LONG TEST" module is a graphical data logger, which helps you observe the long-term behavior of a watch. Various chart indicators are available, such as average rate, moving rate history, rate drift over time, and more. Long-term measurements for up to 12 hours can be conducted for in-depth analysis of the watch being tested. Timegrapher X Pro (in-app upgrade) provides these additional features: • Save and share branded, printable PDF reports for each measurement • Export raw measurement data as a .csv file for spreadsheet analysis • Conduct long-term measurements for up to 120 hours For demo videos and documentation, please visit: https://timegrapher.app/

Verdict

The call

The clearest difference is price: OCEANUS Connected at Free against Timegrapher X's $29.99. OCEANUS Connected also leads on in-app purchases (none vs 1) and rating (4.6 vs 4.2). Timegrapher X's advantage is review sentiment (70% vs 44%) and chart position (#188 vs unranked). On update cadence, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

OCEANUS Connected holds the better App Store score, 4.6 against 4.2. That said, the two scores are not equally well evidenced: OCEANUS Connected has 119 ratings behind it against 23, so its average is the more settled of the two. Written reviews complicate that: 44% of OCEANUS Connected's written reviews are positive against 70% of Timegrapher X's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on October 14, 2026 and October 18, 2026 respectively.
