Quick verdict

Usly is a private space for two, with a shared diary and voice messages. inlove does one job: counting love days on iPhone, free with ads.

Usly comes from SilverAI in Hanoi, launched in July 2026 and runs on iOS and Android. It is free to download, with weekly, yearly and one-time purchases, but the store never says what paying adds. Its App Store privacy label and its Google Play Data safety section contradict each other.

inlove, by developer Danh Huynh, has been on the App Store since December 2017 and holds 4.7/5 from over 276,000 ratings in Vietnam. The free version is fully usable, and a one-off purchase removes the ads. It has not been updated since September 2024.

The description does not mention syncing between two phones.
→ Usly is built for back-and-forth between partners; inlove works more like a personal counter.
What the free version covers[1],[2],[11],[12]Free to download; the listing says "Free to start" without saying what is paid. One Vietnam App Store reviewer says almost all features are free.Every feature works for free; the cost is ads.
→ inlove's free scope is clear; Usly has not published where the paywall sits.
Paid options (personal)[1],[2],[11],[12]US App Store: Weekly $4.99, Yearly $19.99 (about $1.67/month), Lifetime $39.99 one-time. No monthly plan.A one-off "Remove Ads" purchase, listed at $1.99 and $2.99 on the US App Store. No subscription.
→ inlove asks for one small payment; Usly sells recurring plans, and Weekly costs the most if left running.
Ads and tracking[1],[7],[11],[12],[14]The sources AppDuo read do not say whether Usly shows ads. Google Play states that data is not shared with third parties.Ads via AdMob. On the App Store the developer self-reports using device identifiers for tracking and third-party ads (not verified by Apple).
→ inlove is upfront about ads and tracking; Usly has not said, so there is no basis for comparison yet.
Shared photos, voice and data[1],[6],[7],[14]Holds both partners' photos and voice notes. The App Store says no data is collected; Google Play says personal info and app activity may be, with encryption in transit and deletion on request. The linked policy is written for another app, Kibori.Per the policy, what you enter stays on the device. AdMob, Firebase Analytics, Fabric and Crashlytics have access to personal information, and error logs include IP address, device name and OS version.
→ Usly holds more sensitive content without saying where or for how long; inlove keeps entries on the device but brings in ad and analytics services.
Platforms[1],[3],[7],[9],[11]iPhone (iOS 17.0 or later) and Android (Google Play, 1K+ downloads).Only the iPhone version is confirmed (iOS 12.0 or later); no Android version by Danh Huynh was found.

→ Usly scores higher on very few ratings; inlove's score reflects a far larger base of users.
Support[4],[5],[13],[14]SilverAI's support page lists email, phone and a Hanoi address, with replies in 2–4 business days at peak times. No Usly-specific help center.The official website holds only the app name and an App Store link; the privacy policy gives no email or other contact.
→ For bugs or billing questions, Usly users have an email and a phone number; inlove users have little beyond the App Store page.

Choose Usly if…

  • You are long-distance and want to swap photos and voice notes inside the app
  • Your partner uses an Android phone
  • You both enjoy keeping a diary together and decorating it with stickers and frames

Choose inlove if…

  • You only want the day count and anniversary reminders
  • You want no subscription and accept ads or a one-off fee to remove them
  • Your iPhone is too old for iOS 17 (inlove needs only iOS 12.0)

What a year costs

With Usly, how you pay drives the total. At US App Store prices, Weekly billing passes the Yearly price within five weeks ($24.95 against $19.99), and the $39.99 Lifetime purchase is one cent more than two years of Yearly. The sources AppDuo read list no trial period. With inlove, the higher of the two "Remove Ads" prices is $2.99, paid once, with nothing to renew. Both sell through the App Store, so refunds go through Apple; neither developer publishes a refund policy of its own on the pages read.

Where the couple's photos and voice notes go

What partners exchange on Usly is photos, notes and voice messages, the most private data a couple has. Yet the App Store's policy link opens silverai.com/privacy-policy, which is written for Kibori (a sticker keyboard app) and never mentions Usly, photos or voice messages. So no document currently says where Usly stores that content or for how long. inlove's policy is built from an online template and carries no effective date. AppDuo's records show no data breach, lawsuit or penalty involving either app.

New app or long-running app

As of 13 November 2026, Usly is under four months old and shipped five bug-fix and performance releases in its first two months. Three of the four reviews shown on the Vietnam App Store mention freezes, lag or failed photo sends, though two of them still praise the app, and a US App Store review reports posts disappearing. The sample is too small to draw conclusions. inlove is the opposite case: it sat at No. 10 in the free Lifestyle chart on the Vietnam App Store when AppDuo checked, yet has had no new version since 13 September 2024. The sources AppDuo read hold no performance data for inlove.

One phone or two

Usly pays off when both partners install it: the widget puts the other person on your Home Screen, the diary is shared, and photos and messages move between the two phones. It suits couples where both are willing to use it. inlove works differently: its description mentions no account or sync, and per its policy the data lives on the device. If both of you want to see the count, the sources AppDuo read show no way to share data between two phones, and say nothing about backing up when you switch phones. inlove's passcode lock keeps the app private when someone else holds your phone.

Frequently asked questions

There is an inlove app on Google Play. Is it the same one?

AppDuo found no app from developer Danh Huynh on Google Play. The similarly named apps there come from other developers, so check the developer name before installing.

Is Usly related to "Usly - Relationship App"?

There is no basis to treat them as one. Usly: Love Counter & Widgets is published by SilverAI (listed as SilverAI Inc on Google Play); nothing ties the other listing to SilverAI.

How do inlove's two Remove Ads prices differ?

The App Store lists both price points without explaining the difference. Either way it is a one-time payment that does not renew.

Do both apps have a Vietnamese interface?

Yes. Per the App Store, Usly offers 11 interface languages including Vietnamese, and inlove offers 5: English, Czech, French, Turkish and Vietnamese.
