YOUR WEBSITES. YOUR ACCOUNTS. A PLACE FOR WHAT MATTERS. Bring work portals, campus tools, personal accounts and travel services together. WebHarbor gives websites their own workspaces and keeps useful information close in a native inbox. KEEP WORK AND PERSONAL SIGN-INS APART Create separate workspaces for the same compatible website, each with its own sign-in state. Spend less time signing out and reduce wrong-account mix-ups. Clear one workspace’s website data when you need a fresh start. New installations include JZ and Trip as two of the three free workspaces. JZ opens as an ordinary website, without built-in bookkeeping integration. Add your own everyday sites too. Port is not included in this release. SAVE IT NOW. FIND IT LATER. Save text and links or bring them in from the iOS Share sheet. Search your inbox, organize by source or thread, open details, copy what you need and mark items read or processed. Set a local reminder to return to an item, so a useful detail does not disappear when you move on. PUT UPDATES AND REMINDERS IN ORDER Connect notifications inside a supported website and manage them by website, account and workspace. Pause new notifications while keeping history, or hide details on the lock screen. Connect scripts or compatible services you configure to bring task results, text, links and updates into WebHarbor. Shortcuts can open a workspace, save information or create a reminder. Adding a URL does not give every website push support. Presentation depends on the service, network and iOS settings. Marking an item processed does not complete an action on its website. START IN YOUR LANGUAGE Choose a language the first time you open the app, then change it in Settings whenever you like. Supports English, Simplified Chinese, Spanish, Japanese, German, French, Korean, Brazilian Portuguese and Traditional Chinese. MAKE IT YOUR SPACE Use up to three workspaces free in total, including the two starter workspaces. Each authenticated installation identity can have up to 50 cloud notifications accepted cumulatively, without a monthly reset. After the allowance is used, the next new notification is rejected by the service, not accepted for delivery. Local reminders, duplicate retries and fetching existing history do not count again. This is an installation allowance, not a lifetime allowance per person; reinstalling or changing devices may create a new identity. The one-time, non-consumable Permanent Unlock removes commercial workspace and cloud-notification quantity limits and adds custom icons, accent colors and manual sorting. Technical and anti-abuse limits still apply. The US base price is US$4.99; the Apple purchase sheet shows your local StoreKit price. No subscription or separate notification charge. Websites apply their own privacy practices and sign-in restrictions.
