moss vs Mission Darkness Faraday Bag
A $23 bag that cuts every signal to the phone inside, closed with Velcro.
Checked 11 November 2026 against MOS Equipment's own pages. We make moss, so we have linked every source below.
What Mission Darkness Faraday Bag is
The Mission Darkness Non-Window Faraday Bag is a soft bag that blocks radio signals to a phone placed inside. The listing names cellular, Wi-Fi, Bluetooth, GPS, RFID and NFC. It costs $23 and was in stock when we checked. You fold the top over twice and press a Velcro seal. There is no lock and no timer, and it is sold for privacy and forensics, not for changing habits.
What moss is
moss is an iPhone app that comes with a small physical stone. You choose the apps that distract you, tap your phone on the stone, and those apps stay locked until you tap the stone again. People who live together can link their phones to share schedules and put their phones down at the same time, while each person keeps control of their own phone. Locking is free in the app, the stone is a one-time purchase, and the household features are a paid add-on.

Where Mission Darkness Faraday Bag is better
- It costs $23, once.
- It works with any phone that fits, with no app, account or battery.
- It silences everything: no call, message or notification reaches the phone.
Where moss is better
- A lock, not Velcro. Unlocking takes a walk to the stone.
- Calls, alarms and maps keep working while the chosen apps are locked.
- Schedules by day of week, so it does not depend on remembering the bag.

Pick Mission Darkness Faraday Bag if
