ADR-0018: The released app is named "Apollo Download Manager"

• Status: Accepted

• Date: 2026-11-05

• Decided by: the Product Owner

• Issue: #346

Context

ADR-0016 named the released app "Velocity Download Manager V2", so that it would install beside V1 with its own folder and uninstall entry. The PO wants a distinctive name of its own for v0.2.0 (#346). "Velocity" is a common word in software and hard to search for, and the current name carries a version number.

The PO's direction for the name (on #346, 2026-11-05): a completely new name, not "Velocity" plus a word; every candidate ends with "Download Manager"; domain availability doesn't remove a name.

The product name shortlist checked more than 150 first words, in five rounds. For "Apollo Download Manager" it found (2026-11-05):

• No download manager or download app with the name, on the web, on GitHub, in Firefox Add-ons or on Flathub. The nearest is "ApolloSource – Game Downloader", a Firefox add-on with 2 daily users.

• The word "Apollo" is widely used in software: Apollo GraphQL, Apollo.io and Apollo Auto, among 41,266 GitHub repositories with "apollo" in the name.

• Domains and GitHub (information only): apollodownloadmanager.com, .app, .io and .dev and the GitHub account apollodownloadmanager were unregistered.

• Not run: the official USPTO, EUIPO and WIPO trademark searches. These checks aren't legal advice; Singlbase Technologies Limited arranges the legal clearance.

Decision

The released app's product name is "Apollo Download Manager". It replaces ADR-0016's "Velocity Download Manager V2" as the name of the install folder, the Apps & features entry, the Start menu shortcut and the window title, from the release that applies it (#347, planned for v0.2.0).

Everything in ADR-0003 other than the product name stands. The app identifier com.velocity.downloadmanager.v2, the data folders, the IPC and native-messaging host names and the extension IDs don't change, because they decide where users' data and registrations live.

Options considered

The PO chose from these, on the multiple-choice question of 2026-11-05.

Rejected during the research: Atlas (an active download manager already has that name) and Orion (a torrent client named Orion exists). The full list and the reasons are in the shortlist.

Consequences

• #347 applies the name: logo, icons and colours, branding.json's releaseProductName, src-tauri/tauri.release.conf.json, the window title, and the documents that describe the installer (PACKAGING.md, COEXISTENCE.md, BROWSER_EXTENSION.md and the user guide). Until then they describe the current release and keep its name.

• The upgrade from 0.1.x is the main risk. Tauri's NSIS installer names the install folder and the uninstall key after the product name, so a renamed release would otherwise install a second copy. #347 must leave one Apps & features entry after the upgrade and keep all data, settings, history, browser registrations and keychain entries.

• V1 and Apollo Download Manager still install side by side: the new name differs from V1's, and the test in crates/velocity-core/src/branding.rs that keeps them apart stays.

• The browser extension's release name follows the product name; #356 redesigns the extension and #240 publishes it. The Firefox add-on ID is permanent once uploaded, so it is chosen with this name in mind.

• The website (#353) and the developer site (#355) use the new name.

Follow-up

• Singlbase's legal clearance of "Apollo Download Manager" (official trademark searches in classes 9 and 42, and any filing) before the first public release under the name. If it finds a conflict, a new ADR replaces this one before #347 ships.

• Not decided here, for #347: the publisher name (today "Velocity Project"), and whether to register the domains and a GitHub organisation for the name.
