Your Licence Tier Does Not Allow Access to This Tweak
This message means the tweak you tapped is part of Premium and your account is on the free tier. Nothing is broken and nothing failed. The app is telling you the tweak is locked rather than pretending to apply it.
Why you see it after tapping something that looked available
If you are on the free tier
Free lets you apply ten tweaks while signed in, or five without an account. That is a real allowance rather than a trial that expires, and the tweaks you apply stay applied.
Premium removes the limit and unlocks every other tweak. Current pricing is on our site.
If you have already paid
Then something is out of step, and it is worth sorting rather than paying again.
Check you are signed in with the same email you used at checkout
Sign out of the app and sign back in
If it still says free, send us a message from the support bubble at the bottom right and tell us the email on your order. We can see your licence from our side and fix it
If you bought RIP Reticle and are using RIP Tweaks
These are two separate products with separate licences. Owning RIP Reticle does not unlock RIP Tweaks Premium. RIP Reticle is no longer sold, but if you own it, it stays yours.
