Packlin

Travel, business trips, camping, events — prepare your gear faster and smarter.
Packlin is a flexible packing checklist app built around one idea: get out of your way. No confirmation dialogs. No Save button. Undo and Redo handle mistakes instantly.
■ Three-layer structure: Pack → Group → Item
Organize like the real world. A backpack is a Pack, a toiletry pouch is a Group, and each item inside is an Item.
Example: Hiking Backpack (Pack) > Snack Pouch (Group) > Energy Bar (Item)
■ Weight tracking
Assign a weight (in grams) to any item. Packlin totals the weight for each pack automatically.
Totals above 1,000 g switch to kg, so you can pack to match your physical limits.
■ Undo / Redo
Delete, reorder, edit — no confirmation required. Made a mistake? Tap Undo to go back up to 10 steps.
■ Drag and drop to reorder
Press and drag any item or group to rearrange it instantly.
■ Move and duplicate
Move items to other groups or packs, or duplicate them. Copy an entire group into another pack to reuse your setup.
■ Pack sharing and backup
· Export any pack as a .packlin file and share it via AirDrop, email, or any other method.
· "Export All Packs (Backup)" in Settings saves everything in one file — perfect for device migration and data safety.
· Importing merges with your existing data without creating duplicates.
■ Display customization
· Beginner mode shows operation hints; Expert mode keeps things compact.
· Set row detail from Minimal (name only) to 3 lines per row.
■ Check and stock linking
Check an item to automatically fill its stock quantity; uncheck to reset it to zero.
Both behaviors can be toggled independently.
