The Free Android Alternative to Opal (No VPN, No $99 a Year)
I looked at Opal because a few readers asked how it compares to CogniFocus on Android. Short version: Opal is built for iPhone first, it costs $99.99 a year for the features that matter and its Android version runs on a VPN that some users say drains extra battery. CogniFocus blocks apps through a native Android plugin, no VPN, and core blocking is free.
That is the whole story if you are in a hurry. Here is the detail if you want it.
How Opal works
Opal started as an iOS screen time app and later shipped to Android. On Android it runs a local VPN to see which apps you open and step in when you hit a blocked one. That is a common approach, plenty of blockers use it, but it comes with a cost. A VPN keeps your network stack active even when you are nowhere near a blocked app. According to AppLass's comparison of Opal alternatives, this VPN-based blocking can add 4 to 6% extra battery drain a day next to a native blocker. Some Android reviews also describe the VPN switching itself back on shortly after being turned off.
The free version gives you a few recurring sessions and a daily focus score. Deep Focus, the feature that locks a session so you cannot quit early, sits behind the paid plan: $99.99 a year, or $8.29 a month.
How CogniFocus works
CogniFocus blocks apps through Android's own usage access system, not a VPN. You pick which apps to block, start a session and the Distraction Shield watches for them directly on the device. Open a blocked app mid session and it gets interrupted before you actually land inside it. No tunnel. No rerouted traffic sitting between your phone and the internet.
The Goblin companion reacts while it happens. Neutral if you are staying on track, annoyed once you drift, cheerful if you finish clean. The block is not silent. Something on screen is responding to what you actually did.

Who should use each
Opal makes sense if you are already on iPhone and Android is a secondary device, or if $99.99 a year for Deep Focus and cross-device reports is worth it to you. It is a mature product with a polished free trial and a design team behind it.
CogniFocus is for people who are Android first and do not want a VPN sitting between their phone and the internet just to block Instagram. If battery life matters to you, or you just want app blocking to work without asking your phone to trust a tunnel it created for itself, that is the gap this fills.
The short version
Opal ported an iPhone screen time app to Android and put most of what works behind a VPN and a subscription. CogniFocus was built for Android from the start and blocks apps natively, for free, with a Goblin that reacts when you slip.
