Timegrapher X vs Testify

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/

Testify lets you run real experiments on your everyday life. Wondering if keeping your windows closed keeps your house warm? Curious whether wearing socks affects your productivity? Maybe you want to see if your sports team plays better if it is raining? Stop guessing and start testing. Set up an experiment with a hypothesis, track your results day by day, and let Testify crunch the numbers. The app automatically picks the right statistical test for your data — Chi-Squared for yes/no outcomes, or a Two-Sample T-Test for measurements — and tells you in plain language whether your results are meaningful or if you need more data. Features: - Create experiments with a hypothesis and a variable to test - Record trials with date, time, results, and optional contextual notes - Automatic statistical analysis with Chi-Squared and Welch's T-Test - Optional Bayesian view showing the probability one variant is better, with a 95% credible interval - Sequential analysis with a Pocock boundary so repeated peeking doesn't inflate false positives - Visual charts comparing your control and treatment groups, with a best-fit trend line for numeric experiments - Confidence intervals so you can see the range of possible effects - Post-hoc statistical power analysis - Sample size estimates that tell you how much more data you need - Plain-English explanations of your results — no stats degree required - Share polished result images with friends or social media - Daily reminders to log your data, with deep links straight to the experiment - Edit experiments and trials at any time, conclude or reopen as your investigation evolves - Track multiple experiments at once with a last-viewed summary card - Home screen widget showing your most recent experiment and a one-tap Add Trial shortcut - First-launch walkthrough to get you started quickly - Light and dark mode support Testify Pro (optional subscription): - Unlimited experiments - CSV import and export for your trial data - Multi-page PDF report export with charts, summary, and trial table Whether you're optimizing your daily routine, identifying patterns, or just settling a debate with yourself, Testify gives you the statistical tools to find out what actually works.
