Deep dives
Here is what switches to FocusFlow actually get you over each specific app.
Bottom line: FocusFlow provides every Freedom feature on Android plus 7 additional hard-enforcement capabilities. Freedom costs $39.99/year. FocusFlow is free.
Bottom line: Opal is primarily an iOS product. On Android, FocusFlow is significantly more capable with stacked enforcement. Opal costs $39.99/year.
Bottom line: Digital Wellbeing is a nudge tool. FocusFlow is a commitment enforcement system. If you have found DW ineffective, FocusFlow is the next step.
Bottom line: AppBlock is a capable single-layer blocker. FocusFlow stacks three layers and adds behavioral features AppBlock doesn't have, all for free.
Migration
FocusFlow's import feature handles block list migration from every major app in one step.
Export your block list as TXT, CSV, or JSON from the other app. Import the file into FocusFlow. It auto-detects the format and matches package names.
Use name-based import — paste app display names like "Instagram", "TikTok" and FocusFlow fuzzy-matches them against installed apps. Review and confirm.
Both apps allow exporting your blocked app list. Export as CSV or text, import into FocusFlow. Your block list is migrated in under a minute.
