Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.

About Cuckoo Clock Calibration
The best and most accurate app for Cuckoo and Pendulum clocks calibration.
Easily measure your Clock beats period and adjust it to a known correct value.
Turn your iPhone into a precise train count sensor with an unbelievable 0.001 milliseconds (1μs) accuracy!!
Get a quick and precise drift reading of how many seconds/minutes your clock is going to gain or loose per day.
Every Cuckoo Clock owner knows that a mechanical clocks are not as accurate as modern day quartz clocks. This is because the clock mechanism is influenced by temperature, humidity, barometric pressure, breeze and others environmental conditions and therefore requires frequent adjustment.

3. Select a reference timing for calibration from the clock reference table or set your own reference timing
4. Read the accuracy level of your clock vs. the reference timing
5. Adjust your Clock pendulum bob to get the best accuracy!
6. Review how many seconds/minutes your Clock will gain or lose per day based on your current calibration
The app will presents your Clock beats period reading as well as BPH (beats per hour) and BPM (beats per minutes) values.
An accurate waveform display of the microphone signal will help you to adjust the tick readings for the best measurement.
Animated Indicators will guide you through the calibration process.
