DataEye | Save Mobile Data App

By vidyamana Last updated Mar 21, 2025

Expanded Features and Functionality

Real-Time Data Monitoring: DataEye provides near real-time insights into how much data each app on your device consumes. This allows users to identify data-hungry apps quickly and take action, such as restricting their access to mobile data.

VPN Integration: The latest version (3.0.6, released June 2024) introduced an “Always-on” VPN feature. This likely enhances security and data compression, potentially reducing data usage further by routing traffic through optimized servers, though it may require additional permissions and could impact speed depending on server performance.
Customizable Data Permissions: Beyond just blocking or allowing data, users can fine-tune permissions for foreground and background usage per app, offering more granular control than many built-in Android data management tools.
Battery Optimization Details: By halting background data, DataEye reduces the frequency of app refreshes and syncs, which are notorious for draining battery life. Some users report noticeable improvements, especially on older devices or those with smaller batteries.

Size and Compatibility: The app is lightweight, with the latest APK at around 6.5 MB, making it suitable for devices with limited storage. It supports Android 4.1 and above, covering a wide range of devices, though optimal performance is likely on newer versions like Android 13 or 14.
Permissions: Requires permissions like ACCESS_NETWORK_STATE, ACCESS_WIFI_STATE, INTERNET, and RECEIVE_BOOT_COMPLETED (to start after reboot). These are standard for data management apps but may raise privacy concerns for cautious users.

June 2024 Update (v3.0.6): Alongside the VPN feature, this update improved the home screen display of data usage per app and fixed unspecified bugs. However, some users reported new issues post-update (see below).
Developer Activity: LotusFlare Inc., based in Palo Alto, seems to have slowed direct engagement with users. Attempts to contact them via email have failed for some, suggesting limited support infrastructure as of early 2025.

Pros:
Highly rated historically (4.3-4.9 stars across platforms like Google Play and Aptoide), with long-time users appreciating its simplicity and effectiveness.
Ideal for users on prepaid or limited data plans, especially in regions with costly mobile data.
Roaming support is a standout for frequent travelers.
Cons and Recent Issues:
Post-Update Bugs: After the 2024 update, users reported apps disappearing from control menus, random blocking/unblocking behavior, and the data saver toggling off automatically.
Wi-Fi Interference: Despite being designed for mobile data, some users note it blocks apps on Wi-Fi, disrupting normal usage.
Lack of Temporary Unblock Feature: A promised feature to alert users and offer temporary unblocking for blocked apps hasn’t materialized for many, reducing flexibility.
Support Woes: With developer contact failing, users are left to troubleshoot independently, which could be a dealbreaker for those needing assistance.

Compared to built-in Android tools (like Data Saver mode), DataEye offers more detailed app-specific control but lacks the seamless integration of native features. Apps like GlassWire or My Data Manager provide similar functionality with better support but may include premium tiers or heavier resource use.
Its lightweight nature makes it a competitor to “Lite” apps (e.g., Facebook Lite), though it’s broader in scope, targeting all apps rather than specific services.

With mobile data costs still a concern globally and battery life a priority as devices age, DataEye remains relevant. However, its recent bugs and lack of developer response could erode trust unless addressed soon. The app’s niche is strongest for users who need detailed control and are willing to work around quirks.
