## What is ZenLock?

ZenLock is an App Blocking App that *forcefully* stops the apps you overuse.

◆ Simple Flow
・Select addictive apps like YouTube, TikTok, Instagram, X, or games to block  
・When you really need them, choose a temporary unlock time (15/30/60 minutes)  
→ Unlocking requires passing a randomly generated 10-character challenge  
→→ This extra step makes you ask: “Do I really want this app badly enough to type it out?”  
・Even while using the app, once the chosen time is up, it will be blocked again automatically  
→ No more “I only meant 15 minutes on YouTube, but suddenly it’s been an hour…”

◆ Perfect for people who:
・Spend too much time on social media or video apps  
・Struggle to stay focused on study or work because of their phone  
・Lose sleep from late-night endless scrolling and regret it the next day  

ZenLock helps you change habits without relying on willpower.  
It’s ideal for anyone who feels guilty about wasted time, wants to secure focus for study, work, or side projects, or simply start a digital detox.

◆ Safe & Private
ZenLock runs entirely on-device using iOS system features.  
No personal data is sent outside.


## Version history (last 5 releases)

### 1.44 — 2025-09-23

Challenge Update (30s, single action)
- Unified Watch and Hold challenges to a 30-second window with a single required
 action. One signal/prompt appears once; complete it once to clear (miss resets)

APP Block Tab Layout
- Added 100pt top margin and 65pt below the button to prevent overlap. Improves 
readability and tap comfort; no functional changes.

### 1.43 — 2025-09-18

・Added a startup guide (makes app search super easy!)
・Fixed the rare bug where it re-locked right after temporary unlock 
・Challenges are now fixed — you’ll see the same one each time
・Removed Haptics from Focus & Hold Challenges, making them a bit tougher
・Overall stability and reliability improvements

### 1.4 — 2025-09-11

# Family Controls API: Enabled URL Blocking
Previously, the Family Controls API was only blocking apps, but now it also supports URL blocking.

# Safe Area Adjustments for Status Bar and Bottom Bar
Fixed an issue on smaller devices where buttons overlapped with the status bar and bottom bar by adjusting the safe area.

# Shield Screen UI Updates
- Added the ZenLock icon  
- Initially planned to include a button to jump directly to ZenLock from the shield screen, but this is not possible due to OS restrictions  
- Quotes, book excerpts, and trivia are now displayed randomly  

# Settings Screen & Custom Unlock Duration
- Previously, unlock durations were fixed. Now users can customize the duration in the settings screen.

---

# Updated Store Screenshots
- The top screen now shows a settings button instead of an info button, so the screenshots have been updated  
- The shield screen has been redesigned, so the screenshots have been updated accordingly

### 1.3 — 2025-09-08

# Unlock Duration Adjustments
Changed the unlock options after entering the challenge code from “15 minutes, 1 hour, 3 hours, all day” to “5 minutes, 15 minutes, 30 minutes.”
This addresses feedback that users often ended up choosing 3 hours or all day once unlocked.

# Stronger Haptics on Wrong Code
When the unlock code is entered incorrectly, the app now provides stronger haptic feedback to clearly indicate the mistake.

# New Unlock Challenges
Since a simple 10-digit code was still too easy once users got used to it, we added new types of challenges instead of just increasing length or complexity:
	1.	Shake Challenge
	2.	Gaze Challenge
	3.	Hold Challenge

### 1.02 — 2025-09-04

No release notes.
