Soujiyi App Review: Can This Clean-Up Tool Really Declutter Your Digital Life?
Introduction
In the age of overflowing inboxes, jam-packed photo galleries, and cluttered file systems, digital cleanliness is more important than ever. Enter Soujiyi—an app that promises to bring the KonMari method to your smartphone. Designed as a digital decluttering assistant, Soujiyi helps users clean, organize, and optimize their devices with smart, intuitive tools and an interface that’s both aesthetic and functional.
But with dozens of cleanup and optimization apps already on the market, what makes Soujiyi different? Is it just another glorified cache clearer, or does it actually offer something that can improve your daily tech hygiene?
We downloaded, tested, and poked around the app for a full week to find out. Here’s our complete review of Soujiyi—from performance and design to features and flaws.
What is Soujiyi?

Soujiyi (掃除機, meaning “vacuum cleaner” in Japanese) is a mobile app designed to optimize and tidy up your phone’s digital space. But it’s not just about deleting junk files—Soujiyi offers a holistic approach to digital wellness. It organizes photos, manages app usage, identifies duplicate files, clears cache, and even monitors digital habits.
With its calming UI and gamified cleaning sessions, the app turns something mundane—cleaning your phone—into a strangely satisfying experience. Think of it as a friendly housekeeper for your mobile life.
User Interface & First Impressions
Soujiyi’s interface is where it shines immediately. Instead of the dark, tech-heavy visuals that dominate most utility apps, Soujiyi opts for a soft, minimalist aesthetic. Light pastels, rounded icons, and soothing animations create a user experience that feels more like a wellness app than a system tool.
Upon opening the app, you’re greeted with a dashboard that shows:
- Storage health (with a “clutter meter”)
- Today’s recommended tasks
- System status (battery, memory, etc.)
- Motivational messages like “Let’s make space for clarity!”
It feels both welcoming and purposeful—like the Marie Kondo of mobile utilities.
Core Features
1. Smart Clean-Up
This feature scans your phone for unnecessary files, including cache, unused APKs, broken shortcuts, and residual data from deleted apps. You’re given a summary of what can be cleaned, with suggestions categorized by urgency.
Bonus: The cleaning process has animated “sweeping” visuals that make it oddly fun to use.
2. Photo & Video Organizer
Soujiyi uses AI to detect:
- Duplicate photos
- Blurry or low-quality images
- Screenshots older than X days
- Video files over a set size limit
You can review them before deletion, ensuring you never accidentally lose anything important. It even gives aesthetic tips like “Too many food pics? Maybe it’s time for a detox.”
3. App Usage Monitor
A digital wellbeing panel shows which apps you use the most, how long you’ve spent on them, and even suggests “focus-friendly” alternatives. If you haven’t used an app in 30+ days, Soujiyi nudges you with a message like “Still need this?”
It’s subtle, not judgmental—a welcome tone in apps that often go too far with guilt-inducing alerts.
4. System Booster
For Android users in particular, Soujiyi offers RAM optimization, battery life extension tips, and app-freeze options to improve performance. While this isn’t groundbreaking, the app integrates these features smoothly without too many permissions.
5. Decluttering Challenges
Perhaps one of Soujiyi’s most unique offerings is its 7-day Digital Cleanse—a gamified routine that helps users slowly clean their devices one step at a time. Each day has tasks like “Delete 10 old screenshots” or “Review your downloads folder,” and you earn badges for completing them.
Performance & Stability
Soujiyi runs smoothly on both mid-range and high-end smartphones. It doesn’t slow down your device or bombard you with ads (a common sin among free utility apps). There is a small banner ad in the free version, but it’s unobtrusive. The Pro upgrade removes ads and unlocks features like deep scanning and custom themes.
Over a week of testing, we noticed:
- About 2.3GB of junk cleared
- App speed improved on an older phone model
- Less storage anxiety (seriously, that matters!)
The app didn’t crash once during use, and battery usage was minimal.
Pros & Cons
✅ Pros:
- Beautiful, calming UI
- Intuitive features that go beyond basic cleaning
- Non-intrusive alerts and helpful nudges
- Great for digital wellness tracking
- Doesn’t require tons of permissions
❌ Cons:
- iOS version lacks some Android features
- Limited automation (you still have to confirm a lot manually)
- Not ideal for power users who want deep system access
Who Is Soujiyi Best For?
Soujiyi is perfect for:
- Minimalists and aesthetic lovers
- Digital hygiene beginners
- People overwhelmed by phone clutter
- Anyone who wants to feel good about cleaning their phone
It may not be powerful enough for tech-heavy users who want to tweak core system settings, but for the everyday user, it hits that sweet spot of being simple, stylish, and surprisingly helpful.
A Word on Alternatives
There are plenty of phone-cleaning apps out there—CCleaner, Files by Google, and SD Maid, to name a few. But most of them are very utilitarian and dull.
Soujiyi wins by making phone cleanup feel like self-care. It’s not just about freeing space—it’s about freeing your mind. For those who like this kind of mindful tech approach, it pairs well with other minimalist digital tools like tbg95, a retro-style browser game platform that’s light, fast, and distraction-free.
Final Verdict
Rating: ★★★★☆ (4.5/5)
Soujiyi proves that utility apps don’t have to be ugly or boring. It brings charm, purpose, and mindfulness into the realm of digital maintenance. While it’s not for hardcore tinkerers or power users, it’s a stellar choice for anyone looking to keep their device tidy without stress.
If you’re ready to let go of digital clutter and make space for things that spark joy—Soujiyi is 100% worth the download.
