I do not have a verified two-day Redmi test record for this specific app, so I will not invent battery, heat, lag, or visual-bug results. The current Play Store version is 3.1, updated on April 21, 2026, and it contains ads and in-app purchases.
The listed package size is about 32.1 MB. The app supports Android 7.0 and newer. Google Play says most tools work offline, while some tools need internet access.
What This App Actually Does
Smart Tools-All in one Tools puts many small phone utilities inside one app. The current listing says it has more than 124 utilities, games, and AI tools.
It includes calculators, converters, timers, QR tools, device information, media tools, text tools, health tools, games, and AI helpers. This can reduce the need to keep many separate utility apps.

Storage Space and Data Use
Version 3.1 is listed at about 32.1 MB. Older versions were smaller, so the current app has grown as more tools were added.
Installed size and cache can change by phone and usage. There is no fixed cache number for every device. Many tools work offline, but AI, weather, currency rates, and other online features can use mobile data.
Permissions and App Safety
Google Play currently says the developer declares no data shared with third parties and no data collected. It also says data is encrypted in transit.
Some tools may use the camera, microphone, location, storage, or phone sensors. Permission needs can depend on the feature you open.
How It Compares to 2 Alternatives
All In One Tools-Smart Toolbox offers 30+ tools and is free, but Google Play says it may share location and device or other IDs with third parties. Smart Tools-Utilities toolbox lists 45+ tools and contains ads and in-app purchases. Smart Tools-All in one Tools lists far more tools, but its 32.1 MB package is also larger.
