Set up a board of labelled buttons, tap them as things happen, and get a clean timeline timed to the hundredth of a second. Then fix any mis-taps and export it.

Built for the moment you can't look away: a lesson you're observing, a match from the touchline, a usability test, a meeting, an animal behaviour study. One big button per thing you care about, a timer that never loses track, and a haptic tick so you never need to look down.

RECORD
• Big buttons with exact timestamps, to the hundredth of a second
• Four button types: exclusive states (starting one ends the last), overlapping events, on/off toggles and single-instant points
• Undo your last tap, pause and resume, or run a timed session that stops itself
• The screen stays awake while you record
• If Android closes the app mid-session, TimeMark offers to recover it

REVIEW
• Swim-lane timeline with totals and percentages per label
• Fix mis-taps afterwards: relabel, nudge start and end, split or delete events
• Add notes so you remember the conditions
• Insights: trends across all your sessions

TEMPLATES
• Ten ready-made boards: UX session, classroom observation, animal behaviour (ethogram), match analysis, meeting talk time, child play (Parten's stages), sports drill, presentation practice, exercise session and riding gaits
• Build your own boards with unlimited buttons and colours
• Share templates as a file so a whole team records the same way

EXPORT
• CSV for Excel, Google Sheets and Numbers
• JSON with ISO 8601 timestamps for analysis in R or Python
• A timeline image to share
• Share to Drive, email or any app; full backup and restore, compatible with TimeMark on iPhone

PRIVATE BY DESIGN
