PeekSmith was designed for magicians, and the messages are staying on the screen. Apple Watch and smart bands are turning off their screens after a while to save battery, and you cannot turn this feature off. PeekSmith is compatible with several apps and has no Apple Watch or other smart device support, too. Dimensions of PeekSmith make it easy to hide it in places where you cannot hide an Apple Watch (like a card box, or your pocket). Finally, PeekSmith's screen is optimized for readability, and we are working with the app developers to maximize the information you can peek at from the screen.
You can buy them in our Electricks Magic Shop. Please visit the PeekSmith 3 product page.
Sure. Apps can use them as input and you can control the device with them, too.
Applications can use the buttons - it reports button events via Bluetooth. It is up to the developer how they handle these events, in our apps you can assign actions to the button presses.
The PeekSmith app should be in the front to work. You should not lock the screen, or switch to another app. There's an option in Other Settings: "Turn OFF screen when covered". If you turn it on, the app will turn off the screen if it detects something in front of your screen (like your pocket), you can use it instead of locking the screen.
It has a rechargeable LiPo battery.
Plug it with the included cable to your computer or wall charger. You can use any 5V charger, even 100W laptop charger. They don't overload the device. The device can be on or off. When the device is off, it will obviously charge faster. You can turn it on to read the battery percentage. When you are charging the device, a slightly higher battery percentage will be reported.
Some "intelligent" chargers are not providing the 5V constantly, but trying to detect if a device is plugged in. If they were designed for mobile phones with 1A/2A charging, they might not detect PeekSmith's 100 mA need, and won't charge.
The exact answer depends on your brightness settings and usage pattern. We have done some tests with brightness level 5 and a few Bluetooth messages per minute, and PeekSmith 3 worked for more than 4 and a half hours. When the screen is empty, power usage is much lower, so we think 5-6 hours of usage is realistic. Our test with brightness level 6 ended up with 3 and a half hours, so it really matters. Make sure you are using the latest firmware, we are always working on improving the battery life.
It is about an hour to fully charge the battery.
