Comments on Lock My Phone (Zen Mode) for Android

★★★★★ Soundhar Pandian · Aug 5, 2026
Best app for phone lock like this app locks my phone according to the timer that I set which makes my time productive and essential for my life. It helps reduce my phone usage and get rid out of my phone addiction.
★★★★★ Kashif Buzdar · Aug 19, 2026
It is a great app, but I have a suggestion the lock can go a maximum limit of 2 digit like 99 hours. Can you increase it to 3 digit. So that if a. person wants to lovk his phone for a week he can.
★★★★★ Umair Ali · Sep 15, 2026
Very good app which help to stop phone addiction. Increàse focus and productivity etc. Thanks to team.
★★☆☆☆ Prashant Negandhi · Jul 24, 2026
I am using lock my phone app regularly, but I see that premium version has some glitch. If I lock and in emergency if I have to unlock it's not allowing me to make payment, whenever I try to make payment it gets locked. Please fix this because in case of emergency even payment options is there but if I'm not able to make payment it of no use
★☆☆☆☆ Virendra Beniwal · Jul 6, 2026
I found a glitch if you tap on payment, and it takes you to app interface and is you change timer to 1 min and save it the running lock will be removed and phone will be unlocked in just 1 minute so not worth it
★☆☆☆☆ Alexandru Moraru · Aug 17, 2026
I have been using this app for a few years, and it has been really helpful, and it improved my sleep schedule. However, I just had to pay €1,19 to unlock my phone, because I was going on a flight, and I needed to show my flight ticket on my phone. When I tried to pay I kept getting an error message and my phone was still locked. Only after many minutes it was finally unlocked, but then I realized I paid multiple times just for unlocking it once, so I would like to get my money back if possible.

❓ Uninstalling works like this: 😱 https://youtu.be/gQVzznHp_84?t=62

❕ This app needs Device Administrator permission. Otherwise it can't lock your phone.

⏩ What's the purpose of this app?

It's not exactly controversial that YOU NEED A ROUTINE. But it's hard to stick to your schedule when the endless entertainment of the internet is available at your fingertips. Lock my Phone kills that lure so you can concentrate on what's actually important.

While your device is locked you can still access the apps on your lockscreen, take phone calls and call emergency numbers (911 etc.) and emergency contacts (see below). If you unlock it during a lock period it will be locked again right away.

☝ Learn how to set one or more of your contacts as emergency contacts with Android's ICE-feature: https://www.youtube.com/watch?v=dE_bbD5vXDU

⏩ Three Main Features:

1. Recurring lock periods, for example to lock your phone every evening during the week after 10 pm.

2. One time lock periods for when you just want to concentrate for 45 minutes while studying.

3. Geocheck-Feature: Only lock your device if you are in a certain area. Helpful so your phone isn't locked while you're out with friends.

⏩ What's the difference between the free and the premium version?

You can only have one lock period in total on the free version, so you can either have 1 one time lock or 1 recurring lock period. You can have unlimited lock periods (of each type) in the premium version.

There are no ads in either version.

Recent changes:
• 🛠 Fixed Fast Lock crash when Android automatically removes the overlay permission.
• 🛠 Added a notification to inform the user when Fast Lock permission is removed and the feature is disabled.
