Full comparison: TaskNote vs Obsidian →
Obsidian charges for its sync service. Getting notes onto the phone for nothing means wiring up iCloud, Dropbox or Git yourself and living with the conflicts. Here sync is part of the thing: sign up and your notes are on every device.

In Obsidian a board comes from a community plugin, which means configuring it and maintaining it as both move on. Here the board is part of the app. Nothing to install, nothing to keep up with, no markdown files to hand edit.

Obsidian keeps files on your machine and sells sync separately, with much of its power coming from plugins you choose and maintain. This arrives assembled: sync, a board, reminders and end to end encryption, with nothing to configure first.
Yes, on the free plan, with no card details. Obsidian's own sync service is a paid add-on on top of the app.
The editor takes Markdown shortcuts as you type, a hash for a heading, two stars for bold, a dash for a list, backticks for code. Notes export as standard Markdown, so nothing is trapped here.
Everything synced here is encrypted end to end, on the free plan. Obsidian offers that through its paid sync. A local vault, meanwhile, is exactly as safe as the machine it sits on.
Yes, in any browser on iPhone, iPad or Android, with nothing to buy. Obsidian's mobile app needs the paid sync before your notes reach it.
The core is: notes, sync, the board, reminders and end to end encryption, with no card details asked for.
Markdown notes, sync at no extra cost, a board built in, encrypted end to end. Free to start.
