## What is WiseSwipe?

If you have multiple credit cards and find yourself calculating which one offers the longest interest-free period before every single swipe—just to let your funds sit in your yield account for a few more days—then this app is made just for you.

WiseSwipe is designed specifically to help you calculate the interest-free period for each card and check future interest-free rankings, ensuring you always use the most cost-effective card for every purchase.

■ Features you might want to know:

• No Personal Data Collected: The app runs completely on your local device with no network connection, no registration, and no cloud servers. It also supports secure, AES-encrypted local backups and exports, making device migration effortless and safe.

• Home & Lock Screen Widgets: Once you add your cards, you don't even need to open the app. With a quick glance at your screen, you can see the best card recommendation and repayment countdowns. We offer multiple widget styles, fully optimized for Dark and Transparent modes, with more designs coming soon.

• Statement & Repayment Notifications:
  - Statement Date Alerts: Get notified right after your card's statement date, helping you lock in the longest interest-free window (up to 50+ days).
  - Due Date Alerts: Receive timely notifications on payment deadlines so you never miss a payment or face overdue interest.

• Interest-Free Ranking Calendar: Tap any future date on the calendar to view the "Interest-Free Ranking," helping you plan your major purchases ahead of time.

• Excluding Cards & Overdue Settings: If a card has accidentally gone overdue, or if you simply want to manage a card without using it for daily spending, we offer multiple ways to customize your interest-free rankings.

■ From the Developer:

Before building WiseSwipe, I tried many similar tools but found none that truly met my expectations. I wanted a clean, secure, and minimal utility—one that has no bookkeeping clutter, doesn't recommend financial products, and strictly keeps the focus on credit card payment cycles and interest-free optimization.

I also specifically wanted lock screen and home screen widgets, allowing me to setup and forget, letting the app quietly serve me right from my screen.

Hope you enjoy using it!

### 5/5 — 无法购买

*2026-07-17*

无法购买

**Developer response:** Hello，新版本中增加了后台重试机制，可以改善因一时的网络波动等原因导致的购买失败。

如果仍然无法完成购买，可以尝试通过以下方式解决：
1. 切换网络
2. 重启应用
3. 重启设备
4. 过一段时间再购买

若以上方法均无效，可以通过邮箱联系我们。感谢支持～

### 4/5 — 无法购买

*2026-07-13*

有bug，无法进行购买。产品还是不错，有想法。

**Developer response:** 哈喽，无法购买，很大原因是由于网络波动或没有为 APP 开启网络权限。因为我这边后台其实有看到非常多购买成功的用户，所以内购本身应该不存在问题。建议可以切换网络或过一段时间再试一下。

下一个版本中，我会把错误信息再细化一下，看看到底是哪一个阶段出了问题。

也谢谢你对 APP 的喜爱～

### 1/5 — 只能用两张卡

*2026-07-12*

使用受限，用其他家的了

### 5/5 — 有 bug

*2026-07-11*

无法购买永久会员，可以看到套餐，点击提示无法获取对应商品信息

**Developer response:** 无法获取对应商品信息，可能有两个原因：

1. 是否开启了网络权限：虽然 APP 本身是可以不联网使用的，但在进行内购时，因为必须与 App Store 进行通信，所以在购买过程中一定要开启网络权限。购买成功后，没有网络也可以使用。

2. APP 发布了新版本：在此期间，内购商品的获取可能受到波动。目前我查看了，是可以正常购买的😊

如果有需要，可以再尝试一下～
