Date Check vs PileTrac Logger

Date check is an easy way to calculate a date in the future, or past, by using any number of days and/or weeks. Simply enter in the number of days, weeks, or both, to calculate the new date. Tap the + button to switch to subtract mode and calculate dates in the past. Tap again to return to addition mode for future dates. Tap the current date to change to a different start date for the calculation. Originally designed for Medical Doctors and Registered Nurses that need to calculate expiration dates of medicines, end dates for prescriptions, and valid documents such as a History & Physical, Date Check can be used by anyone who needs to know a specific date in the future or past.

PileTrac Logger is a field tool that turns your phone's microphone into a real-time pile driving monitor. Accurately detect hammer blows, calculate stroke heights, and generate professional PDF reports — all without an internet connection. Built for pile driving inspectors, contractors, and geotechnical engineers, PileTrac Logger eliminates manual counting and paper logs so you can focus on the work happening in front of you. KEY FEATURES Real-Time Audio Detection Automatically detects each hammer blow using your device's microphone. No external hardware or sensors required — just press Start and let your phone listen. Automatic Stroke Height Calculation Calculates the hammer stroke height for every detected blow based on the time interval between impacts. Supports a built-in database of industry-standard pile driving hammers. Detailed Session Logging Tracks blow count, depth, stroke height, and timestamp at each depth increment. Expand any log entry to view individual blow-by-blow details. Hammer & Pile Database Select from a comprehensive database of diesel pile hammers. Choose from H-piles, pipe piles, square piles, octagonal piles, and circular piles with standard section sizes (AISC and EN standards). Bearing Capacity Estimation Quickly estimate nominal pile resistance using the Modified Gates formula (Rn = 1.75√E·log(10N) - 100) directly in the field. Input stroke height and blows per inch to get an instant result. Adaptive Sensitivity & Calibration Calibrate the ambient noise floor in seconds. Choose between auto-sensitivity or manually adjust the detection threshold with a simple slider to handle any jobsite noise condition. Professional PDF Reports Generate clean, well-formatted PDF reports that include project details, pile information, hammer specifications, and a complete driving log.
