Möbius Sync brings Syncthing to your iPhone or iPad, allowing you to synchronize selected files between iOS devices and other devices supported by Syncthing, without the need for any cloud service. Supports multiple folders and multiple remote devices. Synchronized folders can be created either: 1. in the Möbius Sync sandbox and files can be added to and retrieved from shared folders via the iOS Files app; or 2. (PAID feature) by accessing other apps' sandboxes. This feature is EXPERIMENTAL and may break other app's functionality. Uses the open-source Syncthing engine internally. Usage within the Möbius Sync sandbox is free up to 20MB. Unlimited file sync, including files in other apps' sanboxes is available for a one-time purchase. NOTE: The functionality unlocked by in-app purchase is identical to that in Möbius Sync Pro (which is purchased up-front).

SalientOps Marine puts your boat’s inventory, maintenance history, manuals, electrical system, checklists and logs in one searchable workspace. Stop trying to remember where you stored a spare part, when you last serviced an engine, or which manual contains the answer you need. Built for boat owners who actually maintain and use their vessels, SalientOps Marine helps you organize the information that normally ends up scattered across notebooks, PDFs, text messages and your memory. KEY FEATURES • Vessel Inventory Track spare parts, equipment, tools and supplies, including quantities and storage locations. • Maintenance Tracking Record completed maintenance, keep service history, and see what is due or overdue. • Manuals & Documents Keep manuals and vessel documents organized so the information you need is available when you need it. • Electrical System Modeling Document batteries, banks, buses, circuits and electrical components to better understand how your vessel is wired. • AI Assistant Ask questions using information from your own vessel records, manuals and documentation instead of digging through files manually. • Checklists & Logs Create repeatable checklists and maintain useful records of work performed aboard your boat. • Journey & Vessel Records Keep important boating activity and vessel information together instead of spread across multiple apps. YOUR BOAT, SEARCHABLE Need to know whether you have a spare bilge pump aboard? Trying to remember the part number for an impeller? Wondering when the generator oil was last changed? Instead of searching through notes, manuals and storage lockers, use SalientOps Marine as the working record of your vessel. BUILT BY BOAT OWNERS SalientOps Marine was created from the same problem many boat owners eventually face: after years of maintenance, repairs, upgrades, manuals and spare parts, keeping track of everything becomes a project of its own. SalientOps Marine gives that information a home. Start with one boat and add information as you go. You do not need to document your entire vessel on day one. Your boat has a story. Keep its paper trail searchable. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Terms of Service: https://marine.salientops.com/help?section=terms-of-service
