Stay focused with intention
Align your screen time with your values. Lockapps like social media or games until your gratitude journal is complete, reinforcing mindful focus rather than willpower battles.
Gratitude-Powered App Blocker & Screen Time Control
Dia Key is a free app lock for iPhone that turns screen time control into a gratitude habit. Lock distracting apps with the built-in locker — unlock only after you journal what you are grateful for.
Why gratitude makes app blocking work
Dia Key combines a smart app blocker with guided gratitude prompts. Each time a scheduled lock activates, you can only unlock your apps after writing a short journal entry. That simple pause reconnects you to purpose, resets focus, and makes healthy habits stick.
Boost wellbeing in minutes
Journaling gratitude increases wellbeing by flipping attention toward what is working. Dia Key keeps the practice consistent, meaning more calm, optimism, and emotional balance.
Build unstoppable habits
Pair your selfcare routine with automation. Automation removes friction so you can repeat the habit daily, stacking productivity and mindfulness benefits over time.

Can I customize prompts?
Yes. Choose quick prompts or write freely. Dia Key adapts to your mindfulness style so the habit stays meaningful.
Is this a free app lock for iPhone?
Yes. Dia Key is free to download on the App Store. It uses Apple's built-in Screen Time APIs to apply the locker — no subscription required to limit screen time and build your gratitude habit.
How does screen time control work?
