Before, a single hiccup replaced the whole tab with an error page. • A background refresh that fails no longer clears the figures already on your screen. • If your account doesn't have access to a section, the app now says so plainly instead of offering a "Try Again" that could never work. • Signing back in after your session expires is more reliable. • The same fixes apply on iPad. ### 1.1.1 — 2026-08-31 CATEGORIES - The icon and color you give a category now follow it across every screen — budget, transactions, accounts, detail views — and match what you see on the web. - Sub-categories keep their own identity instead of sometimes borrowing their parent's. - Change an icon on the web and the app picks it up the next time you open it. BUDGETING - You can now set a budget for every one of your categories. Previously only a fixed handful were offered. - Payments your clients report by Zelle or Venmo can be confirmed from your phone. - Split a bill someone else helps pay. - Recurring bills show what you'll actually be charged. QOL - Refreshed toolbars and tab bars, better contrast on booking requests, and two icons that were silently rendering as blank space. - Your own wording for videos and galleries now shows up on client-facing screens. ### 1.0 — 2026-08-17 No release notes. ### 1.1.0 — 2026-08-15 A better portal for your clients. - Client project pages have been rebuilt around what's theirs: status, their shoot schedule, their invoices, and their deliverables — plus a one-tap way to message you right from the project. - The project timeline is now a live status display for clients, updating as you move the work forward. - Message threads now show clients who they're talking to — your business, your logo. - Paying an invoice is front and center everywhere a client opens one. Smarter booking requests. - Location fields now suggest real addresses as your clients type. Quality of life - Change your profile photo right from the top of Settings. - The app now properly asks for notification permission, including during setup — and the Settings toggle tells you the truth about it. - Removed a number of buttons and links that did nothing when tapped. - Assorted fixes and polish. ### 1.0.1 — 2026-08-14 Notifications, front and center. • Notifications now glide down from the top of the screen — pull down for your full history, organized by category with unread counts. • Get a push notification when someone replies to your messages. • The app icon badge now means something: it counts what's new since you last checked, and clears when you open the app. • Tapping a notification takes you straight to the exact task, project, invoice, booking, or conversation it's about. A better way to work with tasks. • Redesigned task editor: clearer sections, a proper status control, and one consistent layout for creating and editing. • Completing a task feels like it should — a satisfying checkmark, then it files itself under Done. Safer client email changes. • Changing a client's email now sends them a confirmation first, so a typo can never lock anyone out. Also in this update: • Links to your portal now open directly in the app. • Easier tapping throughout — we enlarged the touch areas on dozens of small buttons. • Share links can now allow downloads. • Project pages list every invoice and let you create another at any time. • General bug fixes and improvements. ## Apps similar to seashellOS | App | Rating | Price | Category | | --- | --- | --- | --- | | [Duffle](https://appshunter.io/ios/app/duffle/id6717603175) | 5.0 (1) | Free | Business | | [Tap Forms Organizer 5 Database](https://appshunter.io/ios/app/tap-forms-organizer-5-database/id1084143351) | 4.7 (1,249) | $16.99 | Business | | [Spoke Phone](https://appshunter.io/ios/app/spoke-phone/id1162123995) | 3.1 (21) | Free | Business | | [EzFill: Gas Delivered](https://appshunter.io/ios/app/ezfill-gas-delivered/id1161173793) | 4.8 (447) | Free | Business | --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
