How Tracing server packs add locale glyph sets without an app update

What Tracing server packs are for

Tomorrow Kid’s bundled lesson path—Lines → Shapes → ABC—ships inside the app. Server packs are the expandable layer beside it: dashboard-published glyph sets that can add new languages, scripts, and age-tuned corridors without waiting for an App Store update.

Parents looking for “trace Myanmar letters,” “kids handwriting new language packs,” or offline practice after first play are talking about this chip row—not Fun traces, Trace your name, or Difficulty.

Parent tip: keep Lines → Shapes → letters as the weekly spine. Open a server pack when you want locale glyphs or a fresh set that matches your child’s language at home.

Where packs show up

1. Open Tracing from Home
2. Look at the chip row on the list—built-in categories sit beside any packs the device has loaded from the dashboard
3. Tap a pack chip to open its glyph grid (title, age range, and progress stars per glyph)
4. The next unfinished glyph is highlighted the same way the lesson path highlights Next-up

Packs load through the app’s tracing manifest (TracingServerPackStore). Once a pack is on the device, kids play it with the same canvas engine as bundled glyphs—only texts, audio, icons, and optional stroke geometry come from the pack.

What’s inside a pack

Each pack carries:

• A title and suggested age range
• Corridor scale (and optional strokesFromAge) so path width can match younger or older hands
• Glyphs with spoken texts and, when available, pre-generated audio in the pack locale
• Icons for the grid; glyphs with no custom strokes reuse bundled geometry by character when the shape is already known

Audio prefers the pack clip first, then falls back to on-device TTS in the pack locale. After the first successful play, SpeechHelper URL caching keeps clips ready offline—useful on travel days once the pack has been opened online at least once.

Progress stars track per pack glyph, separate from the Lines → Shapes → ABC lesson path, and still feed the familiar Sticker Book language.

How packs differ from other Tracing surfaces

• Server packs — chip-row locale / dashboard glyph sets; manifest content + audio; offline after first play
• Bundled lesson path — Lines → Shapes → ABC / abc / 123 inside the app (main Tracing guide)
• Teen numbers (11–20) — digit-by-digit sequences on the 123 grid (teen numbers guide)
• Fun traces & Doodle — come-alive scenes and no-fail free draw (Fun & Doodle guide)
• Trace your name & Trace a word — profile name and picture words (name & word guide)
• Tracing Difficulty — Auto / Easy / Medium / Hard path width in Settings (Difficulty guide)
• Pencil styles — cosmetic ink under the canvas (pencil guide)
• Left-hand mode — L / R chrome mirror on the list header (Left-hand guide)

Difficulty, pencils, and Left-hand mode still apply on pack play the same way they do on bundled glyphs—packs change what is traced, not those parent/kid controls.

A calm way to introduce packs at home

1. Open Tracing together and notice which pack chips appear beside the built-in categories.
2. Pick one pack that matches your home language or a script you want to explore.
3. Finish one glyph online so audio can cache, then try the next unfinished glyph later without Wi‑Fi.
4. Leave Difficulty on Auto and celebrate pack stars the same way you celebrate lesson stars.
5. Return to Lines or Shapes tomorrow so the pedagogical path stays the spine of the week.

What to try next

When you want handwriting in a new locale without waiting for an app update, open Tomorrow Kid → Tracing, tap a server-pack chip, and finish the highlighted glyph. Keep the bundled lesson path for daily stroke control; use packs for the expandable glyph sets your family actually speaks and writes.
