Changelog
Stay updated with the latest features, improvements, and fixes in CineMath
v1.3.0
majorComing Soon15 Free Calculators in Three Groups
New Camera calculators: Depth of Field (with hyperfocal distance and split focus), Field of View, Focal Length Match, Exposure, Close Focus (extension tubes and diopters) and Anamorphic. New Storage/RAID and Time Lapse calculators. Every calculator is free.
Merged Calculators
Data & Storage solves for storage, runtime or bitrate (it replaces Time to Data, Data to Time and Target Bitrate). The Timecode Calculator now converts frames to timecode and back. Film ↔ Time works in both directions. Aspect Ratio includes Sizing.
Professional Tools
Camera Database with 149 cameras and maker-published data rates for each frame rate, Multi-Camera Compare, Data Planning with LTO archive plans and a PDF report (Producer Summary or Technical Report, with your name, company and logo), Productions and Timed Notes. Part of CineMath Professional.
Share Links
Share Data Planning reports, Timed Notes and calculation history as links on cinemath.app, with an optional password, expiry date and view limit. Manage and revoke them in Settings › Shared Links (Professional).
New Calculator Layout
Pick a calculator from its title (⌘E on Mac), enter values in inline rows, and see results in two panes on iPad and Mac. Depth of Field, Aspect Ratio, Film ↔ Time and Storage/RAID draw a diagram of the result, and each result value can be copied on its own.
Settings and Accessibility
Dynamic Type throughout the app, optional haptics on iPhone, a Share Usage Analytics switch in About & Legal, and a Made by Bradford Operations section. The Glossary page is gone, and the app is in English while translations are finished.
Accuracy and Stability
Camera data rates checked against each maker's published figures for all 149 cameras, plus fixes across the calculators and the PDF report.
