My Experience with EBook sách hay
I downloaded this app a few months back because my train ride to work was boring and I wanted to read more in Vietnamese without spending money. I’m the type of person who will test every single free feature before even thinking about paying, and I was fully expecting to hit a paywall or a “premium only” section after a week. It never happened. Last Tuesday, I was stuck on the delayed 7:15 AM train for an extra twenty minutes, and I just opened the app and picked up where I left off in a historical fiction novel. No hassle, no login prompts asking for money. It just worked. For a free app, that’s pretty much all I ask for. It’s become my default for killing time.
Features Worth Noting
The library is honestly impressive for something that costs nothing. I’ve found everything from old classics by Nam Cao to modern romance and a ton of those self-improvement books my mom is always telling me to read. The search is basic, but if you browse the categories like “Truyện Ma” or “Kỹ Năng,” you’ll stumble on good stuff. The offline download is the real hero for me. I grab a couple of books on my home Wi-Fi and I’m set for the week, no worrying about cell service in the subway tunnels. The reading screen is clean. I changed the font to a bigger size and use the dark mode at night, which makes reading in bed easy on the eyes. It remembers my place in every book, which sounds simple but a lot of free apps mess that up.
What Needs Work
The ads are the obvious downside. The banner at the bottom is fine, I can ignore that. But the full-screen video ads that pop up sometimes when you turn a chapter or go back to the home screen are frustrating. I was really getting into a suspenseful part of a story last Thursday evening, swiped to the next chapter, and bam—a 30-second ad for a mobile game. It kills the mood. Also, while the app is stable, the design feels a bit old. Scrolling through the library can be a tiny bit sluggish on my Pixel 7, which shouldn’t happen. It’s not broken, it just doesn’t feel as slick as some other readers.
Pricing
This is the best part. The app is 100% free. No subscriptions, no coins to buy, no chapters locked behind a paywall. You get every book in the library without paying a cent. I used it for months, waiting for the other shoe to drop, and it never did. The price you pay is your time watching ads. For someone on a budget like me, that’s a trade I’m willing to make. You get a lot of value here for literally zero dollars.
Developer Notes
The developer is listed as Anh Thu Vu. I haven’t needed to contact support, but I check the Play Store reviews now and then. Some people complain about the ads (which, fair), but others mention the developer actually replies to feedback. I’ve seen the app update every few months, usually with “performance improvements” or “bug fixes.” More importantly, I notice new books in the “Mới Cập Nhật” section every couple of weeks, so it seems like someone is still adding to it. That’s a good sign. It’s not some abandoned app.
Security & Privacy
I got it from the Play Store like everyone else. When I installed it, it asked for permission to access my device’s storage, which makes sense so it can save the downloaded books. I didn’t see any requests for weird permissions like my contacts or location. The privacy policy is linked in the store listing. Since it’s ad-supported, they’re probably collecting some data for that, which is standard for free apps. It hasn’t done anything sketchy on my phone, and my antivirus hasn’t flagged it. For a free reading app, it feels as safe as any other.
Can I download books to read offline for free?
Yes, you can download books to your device using your home Wi-Fi and read them offline without any cell service. This is a great feature for commuters on subways or trains, and it doesn't require a paid subscription.
Does the app have a dark mode and adjustable font size?
Yes, the reading screen includes a dark mode for comfortable nighttime reading and lets you change the font to a larger size. The app also automatically remembers your place in every book, so you never lose your spot.
Why do full-screen video ads keep popping up when I turn a chapter?
Those are ad placements that can interrupt your reading, especially when swiping to the next chapter or returning to the home screen. While the banner ads are easy to ignore, these video ads can last up to 30 seconds and may kill the mood during an exciting scene.
How can I fix the app feeling slow or having an outdated design?
The app's design is a bit old and the library scrolling can feel sluggish, but it remains stable for reading. Unfortunately, there isn't a built-in fix for the interface, so we recommend keeping the app updated and using the category browsing feature to find books more efficiently.
How does EBook sách hay compare to paid reading apps like Kindle or Google Play Books?
Unlike paid competitors, this app offers a large Vietnamese library completely free with no premium paywall, including classics and modern genres. However, it lacks the polished interface and ad-free experience of paid apps, so you'll have to tolerate occasional full-screen ads in exchange for zero cost.
