Show HN: NowThis – OSS task manager for Nextcloud and iOS supporting subtasks
A developer built NowThis, an open-source task manager for Nextcloud and iOS that supports subtasks via CalDAV, aiming to combine native Apple Reminders-like performance with self-hosted data storage. The app includes calendar integration and widgets, and is available through GitHub and Apple TestFlight.
Background
- CalDAV is an open standard (RFC 4791) that lets calendar and task data sync between clients and servers. Nextcloud, a popular self-hosted cloud platform, includes CalDAV support so users can manage tasks without relying on Google, Apple, or Microsoft servers.
- "ETag" (entity tag) is a version marker that tells a client whether data has changed. Some CalDAV clients ignore it for subtasks, causing sync conflicts or lost changes — the developer wanted to fix that.
- "OSS" means open-source software (the code is public). TestFlight is Apple's beta-testing platform for iOS apps.
- The audience for this: people who use Nextcloud (often for privacy or data sovereignty) but found iOS task apps were either slow web views or didn't handle nested subtasks correctly, forcing them to choose between native feel and self-hosted data.
