Linden is an AI app blocker for Android. To open TikTok, Instagram Reels, or YouTube Shorts, you talk to Lumi — an AI gatekeeper who argues with you and decides whether your reason clears the bar. Pricing below.
Plans
| Plan | Price | Per month | Includes |
|---|---|---|---|
| Free | $0 | $0 | 1 Lumi personality, limited Lumi conversations per day, basic blocking, no friend mode. |
| Monthly Pro | $7.99 / month | $7.99 | All 6 personalities, hardcore mode, friend approval codes, streak tracking, hours-saved stats, achievements. |
| Yearly Pro | $79.99 / year | ~$6.67 | Same as Monthly Pro. Saves you ~17% vs monthly. Recommended for actual habit change. |
Why no free trial?
Trials are great for software you might use. They are bad for software you must want to use. Phone-addiction blockers fall in the second category. Every free trial we have ever shipped resulted in roughly the same outcome: users install, poke, never set a real blocklist, never have a real conversation with Lumi, then either churn silently or convert at well below the rate of paying users from day one.
$7.99 for one month is a small commitment in absolute terms. But the act of paying flips a small switch in the brain — you have skin in this. That switch is the difference between "let me see what this is" and "let me actually do this".
Pay $7.99 for a month. If Lumi does not change something for you, cancel inside Google Play and we never bother you again.

FAQ
- How much does Linden cost?
- $7.99 a month or $79.99 a year on Android. The yearly plan saves you about 17% versus paying monthly. iPhone version is coming once Apple approves the Family Controls entitlement.
- Is there a free trial?
- No. Trials select for "let's see what this is" energy. We need "let's actually fix this" energy. $7.99 for one month is a small enough commitment that real intent self-selects.
- Is there a free version of Linden?
- Yes — a limited free tier with one Lumi personality, basic blocking, and a daily cap on Lumi conversations. The full thing (all 6 personalities, friend mode, hardcore mode, achievements) needs Pro.
- How does Linden's pricing compare to Opal?
- Opal is iOS-only and runs about $99.99/year (~$8.33/mo) for analytics-first screen-time tracking — no AI conversation layer. Linden is Android-first at $79.99/year, and the gatekeeper Lumi negotiates with you in real time. Full comparison at /vs/opal.
- How do I cancel Linden?
- Open Google Play → tap your profile → Payments & subscriptions → Subscriptions → Linden → Cancel. The cancellation is instant; you keep access until the end of the paid period.
- What payment methods does Linden accept?
- Whatever Google Play takes in your country — credit and debit cards, Google Pay balance, carrier billing where it's offered, and in a lot of regions, PayPal.
