Import and Export Guide

Which Timers Support Import/Export?

Import/export is available on all timers where you build or customize setups. Supported timers include:

• Interval Custom — multi-interval cycles
• Interval Presets — preset work/rest intervals (Tabata, 30/30, etc.)
• HIIT Custom — high-intensity protocols with custom phases
• HIIT Presets — preset HIIT protocols
• EMOM — every-minute-on-the-minute
• EMOM Splits — EMOM with split tracking
• AMRAP Simple — as-many-rounds-as-possible
• AMRAP Splits — AMRAP with split tracking
• Tabata — classic Tabata (20/10) with customizable rounds
• Countdown — custom countdown timers
• Countdown Presets — preset countdown durations
• Stopwatch — lap timing
• Stopwatch Splits — stopwatch with split tracking
• Pyramid — progressive work/rest schemes
• Mobility — multi-activity sequences
• Custom — fully customizable multi-phase workouts

Preset timers as a starting point: Timers like Interval Presets, HIIT Presets, and Countdown Presets offer preset chips (e.g., Tabata, 30/30, 1:00) that load default values. You can use these as a starting point—tap a preset, then open Set Up to modify rounds, times, title, and other settings. Your customized configuration can be exported and re-imported anytime, so you can save tweaked versions of preset-based workouts without rebuilding from scratch.

📤 How to Export Your Workout

1. Set up your timer with custom times, rounds, etc.
2. Click the Export button (usually near the setup area).
3. The browser downloads a .json file automatically.

📁 Default File Naming & Renaming

When exported, files use a clear convention: timerist_[workout-title]_YYYY-MM-DD_HHmm.json. The workout title comes from your workout name (or a default like "Interval" or "EMOM" if none is set), sanitized to letters, numbers, hyphens, and underscores (max 40 characters). The timestamp includes both date and time. For example: timerist_My-Custom-HIIT_2026-02-28_1430.json or timerist_Interval_2026-02-28_0915.json. You're free to rename the file anything you want afterward (e.g. leg-day-burner.json or favorite-emom.json)—it will still import perfectly as long as the file contents (JSON structure) remain unchanged. The system reads the data inside, not the filename.

📥 How to Import a Workout

1. On the timer page, click the Import button.
2. Select your .json file from your device.
3. The settings load automatically—review if needed, then start your workout.

📁 Finding Your JSON Files on Devices

Help locating exported or shared files:

• iPhone/iPad: Open the Files app → look in iCloud Drive > Downloads, or On My iPhone > Downloads. If shared via text message (Messages) or email, tap the attachment → "Save to Files" → choose Downloads or a custom folder.
• Android phone/tablet: Open the Files/My Files app → tap Downloads folder (usually Internal storage > Download). For shared files: In Messages or Gmail, tap the .json attachment → Download or Save → it goes to Downloads.
• Windows desktop/laptop: Open File Explorer → click Downloads in the left pane (typically C:\Users\[Your Name]\Downloads). Email/text attachments save here or to a chosen folder when you download.
• Mac (Macintosh): Open Finder → select Downloads from the sidebar (or Go > Downloads). Shared attachments from Mail/Messages save to Downloads by default.

JSON Example

A simple snippet of what an exported config might look like:

{
  "type": "interval",
  "intervals": [{"work": 30, "rest": 10}, {"work": 45, "rest": 15}],
  "rounds": 8,
  "name": "My Custom HIIT"
}

You have the option of just exporting the files and importing the file from your desktop, iPad, or smartphone. You can also register and store workouts & timers in the Timerist cloud storage either privately or publicly, depending upon your publication settings.
