Full Power

Opening the app for the first time

The moment you install Full Power and tap the icon, you are met with a login screen. This is not an app you can browse anonymously. You need an account to do anything. The screen is minimal, with fields for email and password, and a small "register" link below. There is no demo mode, no tour, and no skip button. If you do not have an account, the app is useless from the first second. This immediately tells you who this app is built for: people who already own compatible smart devices from the KISO ecosystem.

Once you log in, the home screen loads a list of available devices. The interface is functional but basic. The font is small, the icons are simple, and there is no onboarding flow to explain what each button does. You are left to explore on your own. The "Add Device" button is the most prominent element, which makes sense because the app's core function is to connect and manage devices. Tapping it opens a scanning screen that looks for nearby Bluetooth devices. The scan is quick, and the app lists any compatible devices it finds. Adding a device is straightforward: tap the device name, confirm the connection, and it appears on your home screen.

The home screen also has a "Schedule" tab and a "Scenes" tab. The Schedule tab is where you can set up timed tasks for your devices. The Scenes tab allows you to create custom automations, such as turning on a light when a door sensor is triggered. These features are promising, but they are not explained anywhere. You have to figure out how they work by trial and error. The app does not have a help section or a tutorial. This is a common issue with IoT apps, but it is still frustrating for new users.

How scheduling and Bluetooth work together

The app's scheduling feature is designed to let you automate your devices. You can set a time for a device to turn on or off, or to change its mode. This is a practical feature for someone who wants to, say, have their lights turn on at sunset or their charger start at midnight. The app also has a Bluetooth local card whitelist, which allows you to manage up to 60 Bluetooth devices. The interaction between these two features is where things get interesting. If you schedule a task for a Bluetooth device, the app needs to maintain a connection to that device at the scheduled time. This means the app has to be running in the background and the device has to be within range.

This creates a practical limitation: if your phone loses Bluetooth connection to the device, the scheduled task will fail. The app does not have a fallback mechanism, such as using Wi-Fi or cloud-based scheduling. This is a significant drawback for users who want reliable automation. The app also does not allow you to set up schedules for devices that are not currently connected. You have to add the device first, then schedule it. This is a logical workflow, but it means you cannot pre-schedule tasks for devices you plan to add later.

Another aspect is that the whitelist limit of 60 cards is a hard cap. If you have more than 60 Bluetooth devices, you cannot add them all. This is a limitation that is not mentioned in the app's description. Users who discover this limit after purchasing multiple devices will be frustrated. The app's changelog mentions increasing the limit to 60 cards, which suggests that the limit was even lower before. This is a positive change, but it also indicates that the app is still evolving and may have other hidden limitations.

Real-world performance and daily use

In daily use, the app is generally responsive. Device discovery is fast, and connections are stable. The interface is clean and uncluttered. However, the app has some rough edges. The design feels dated, with a color scheme that is mostly blue and white. The text on some buttons is cut off on smaller screens. There is no dark mode, and the app does not rotate to landscape. These are minor inconveniences, but they add up over a full day of use. More importantly, the app does not have a built-in messaging or notification system. If a scheduled task fails, you do not get a notification. You only find out when you check the device manually.

The app's performance is mixed. Basic functions, like turning a device on or off, work reliably. However, more complex features, like scheduling, are unreliable. One user reported that the charging schedule feature is "a complete mess" and that it stops working every second time you use it. The user also noted that once a schedule is set, you cannot deactivate it without resetting the app. This is a critical flaw for a feature that is meant to make life easier. The app's stability is also a concern. The same user reported that the app "stops working every second time you use it." This suggests that the app has memory leaks or other stability issues that have not been addressed in recent updates.

The app's privacy policy states that data is not shared with third parties, but it does not specify how long data is retained or whether you can request deletion. The app collects personal information, messages, and two other types of data. Data is encrypted in transit, which is a positive point. However, the lack of transparency about data retention is a concern for users who value their privacy.

The version history and its implications

The app's changelog is consistently "fix bugs." This is a generic phrase that tells you nothing specific. Looking at the version history from APKPure, you can see that the app has been updated frequently over the past few months, with version numbers jumping from 3.1.28 to 3.1.36. Each update is accompanied by the same vague description. This pattern suggests that the developer is iterating rapidly, but they are not transparent about what exactly is being fixed or improved.

This lack of detail is a problem for users who want to know if a specific bug they reported has been addressed. The one user review we found complains about the charging schedule feature being broken. There is no way to know if this has been fixed in the latest version. The developer's response is always to try the latest version and report back. This creates a frustrating cycle where users have to test each update themselves to see if their problem is resolved. The app is meant to be a reliable tool, but the lack of communication undermines trust.

One positive aspect is that the updates are small and fast to download, usually under 105 MB. The update process does not require a restart, and the app continues working in the background. This is a smooth experience compared to some other IoT apps that force a full restart. However, the frequency of updates means that you are constantly downloading new versions, which can be a drain on mobile data if you are not on Wi-Fi. The app does not have an option to disable automatic updates, so you are forced to keep up with the latest version whether you want to or not. The developer's location in Ningbo, China, and the use of a Gmail domain for contact information suggest that this is a small-scale operation, which may explain the lack of detailed changelogs and the slow response to user feedback.
