Cycle Time – stopwatch
Cycle Time - stopwatch


Category: Analysis

Cycle time app is made by engineers for engineers. It combines an high-accuracy industrial stopwatch with real-time statistics.

With this app you can measure the mean cycle time of any automated process and see other statistics in real-time (part per hour for example). Tap on the lap button to start measuring and see the stats being recalculated at each lap.

If you are using this app for work, we recommend you to subscribe and access all features designed for professionals.

By subscribing to full version you could store times in a database for each process. You could then retrieve those times anytime and continue adding new samples. Also, you could export samples into a .CSV file and open it with Excel for further analysis.

We are eager to receive your feedback and continuously improve the app. For this reason, we provided the app with a simple button to ask for new features. Just tap on settings->bug/feature request. We listen to all requests and develop the most wanted ones in order to keep offering you the best stopwatch for engineers.

StarStat is a free statistical calculator designed to easily perform tests of statistical significance on your survey data.

Survey researchers use significance testing as an aid in expressing the reliability of survey results. Phrases such as “significantly different,” “margin of error,” and “confidence levels” help describe and make comparisons when analyzing data.

The purpose of this free tool is to aid researchers in performing appropriate statistical tests for data analysis.

StarStat includes 3 different tests:

Z-test Calculator:
The z-test of proportions is used to test the difference between proportions (percentages) for two groups. Statistics computed provide the probability that a difference at least as large as noted would have occurred by chance if the two population proportions were in fact equal.

T-test Calculator:
The t-test of independent means is used to test the difference between means for two groups. Statistics computed provide the probability that a difference at least as large as noted would have occurred by chance if the two population means were in fact equal.

Sample Precision Calculator:
Sample precision or margin of error calculations determine a conservative estimate of sampling error for a given sample size. These estimates are helpful in answering questions like: “How large a sample do I need?” or “How reliable are my survey results?”

StarStat was developed by DataStar, Inc., a leading provider of survey management and data processing services, specializing in web surveys for employee and customer feedback. For more information, contact us at


Category: Analysis

StaTable provides immediate access to twenty five most commonly used statistical distributions. With just a few keystrokes, the tail area or percentage point you want appears in a window. StaTable eliminates hunting for books of tables, interpolation, and risk of calculation error.

The following statistical distributions are accessible in StaTable.

Continuous: 1) Normal, 2) Chi-Square, 3) Student’s t, 4) F-distribution, 5) Lognormal, 6) Bivariate Normal, 7) Exponential, 8) Gamma, 9) Weibull, 10) Uniform, 11) Beta, 12) Triangular, 13) Cauchy, 14) Gumbel, 15) Pareto, 16) Logistic, 17) Non-Central Chi-Square, 18) Non-Central Student’s t, 19) Non-Central F

Discrete: 20) Binomial, 21) Multinomial, 22) Poisson, 23) Negative Binomial, 24) Hypergeometric, 25) Geometric

Looking up Table Values: If you are looking up probabilities for a given variate value simply type the value(s) into the top-most cell(s). The desired probabilities will be computed and shown in the bottom group of probability cells.

If you are looking for the percentile point for a given probability, enter this value in the appropriate probability cell. The top-most cell will then display the required percentile point value.
