Start a checklist

Choose a Work, Gym, Swimming or Travel example, or create your own list.
Add items and edit their names for your situation.
Tap an item as you pack it. Tap again to clear its check.

Rename a list or duplicate it for another occasion. Examples are general starting points; adjust them for your destination, facility rules and travel requirements.

Use the same list again

Pack again clears the checks in the selected list. The list and item names remain. After resetting checks, deleting a list or item, deleting all lists or restoring a backup, Undo can restore the previous state once within 8 seconds and before the next save. Creating lists or items, renaming, toggling checks, changing preferences and duplicating lists do not offer Undo. Undo is not preserved after the app closes.

The app manages checks you enter. It does not automatically confirm whether you have an item or send reminders.

Storage limits

Keep up to 50 lists, with up to 100 items per list. List names can contain up to 40 characters and item names up to 80 characters. New saves also have a 1MiB UTF-8 data-size limit, which may be reached before the count limits. Existing data is not automatically removed when a limit is reached.

Backup and changing devices

Export a backup in Settings to save lists, items, checked states and preferences as a JSON file. The file is plain text, so check where you save it and whom you share it with. Restore backup reads a JSON file exported by this app and, after confirmation, replaces all lists and preferences on the current device. It does not merge data. Language and appearance preferences are replaced with the backup values.

File selection reads at most 4MiB. A separate 1MiB limit applies to the data being saved. Invalid or oversized backups do not change existing lists. Delete all lists and backup restore also offer one Undo within 8 seconds, before the next save. Uninstalling the app or deleting all lists does not delete exported files. The Company does not keep a server copy of your checklists; keep your backup files safe.

Language and appearance

In Settings, choose Korean, English, Spanish (Latin America), Portuguese (Brazil), Indonesian, Hindi, Japanese, German or French and light, dark or device appearance. Changing the interface language keeps list names and item names as entered.

Advertising privacy

The app includes Google AdMob banners below the list-selection and item-checking screens. Checklists remain usable if ad requests are not permitted or an ad cannot be displayed because of a connection problem. A privacy form may appear depending on your region and applicable requirements. Where applicable, the advertising privacy entry in Settings lets you review or change your choices.

Report a problem

Email dev@ibrdos.com with your device model, operating-system version, app version and the steps leading to the issue. Do not send passwords, identity documents, payment information or other sensitive details. Lists and backups are not automatically attached to your message.
