Math for Middle & High School 4+

The App itself and the description indicates that this App’s Subscription provides:

Unlimited use of all content
All topics with unlimited access
Calculators
Info graphics
Charts and animations
No ads
Subscribe now for better results!

The problem is, that you can’t even use the app whatsoever without a Subscription! The Subscription Screen (with the above noted message) will not disappear to access any content, and thus it’s a paid app, without any content use without a Subscription. It’s sad b/c I actually have other apps by this Developer.

Hello JesusLoverRN, thanks for your feeedback. There were already some other user that requested a change about the subscription handling. I will take your comment into account. I will try to find a better solution in the next 2 updates. Right now I am working on a new topic which will come with the next update. Sorry for the delay.

At the moment it is followed by Apples recommendation. So how can you handle the subscription in Apples way:
1. Subscribe the app for 1 month with 1 week free trial.
2. Go to your device settings
3. Tap your name on the top
4. "Subscriptions"
5. Kill the subscription

You should not be charged that way as long as you use the monthly subscription and revoke it within the first week.

Should a problem occur you can refund it this way: https://support.apple.com/en-us/HT204084

Kind regards

开始时，可以免费下载使用，现在更新了，旧版不给钱还不给用了。吃相太难看。

Hello Jhoodong, it is the same circumstance the previous reviewer wrote before. I am sorry for your bad feelings. It is true that we started a price model on this app. But this app was completely free for a half year and took like 6 years of development to provide all the topics in this high quality. As a beta-user you also did receive another month for free. Anyways, thank you for using this app. I'm glad to hear that this app has been of great use to you. With kind regards.

你好，Jhoodong，这和审稿人之前写的情况是一样的。我对你的不良感受感到抱歉。确实，我们在这个应用程序上启动了价格模型。但这个应用程序在半年内完全免费，并且花了大约 6 年的开发时间才提供如此高质量的所有主题。作为测试版用户，您还可以免费获得一个月的服务。无论如何，感谢您使用这个应用程序。很高兴听到这个应用程序确实为您带来了巨大的好处。亲切的问候。

垃圾开发者！开始就说你计划要订阅制、我都懒得下载

Hello! I am sorry for your bad feelings about this situation. In the early phase the app was fully for free with all features and topics. That is true. To cover the costs for the past and the ongoing development we have to set a price. But the costs are transparent and the usage is unlimited when it is paid. If you need more information don't hesitate to contact us at contact@gslstudios.com. But I am glad to hear that there are no malfunctions to complain about. Kind regards.

你好！对于您对这种情况的不良感受，我深感抱歉。在早期阶段，该应用程序完全免费，包含所有功能和主题。那是真实的。为了支付过去和正在进行的开发的成本，我们必须设定一个价格。但费用透明，付费后使用不受限制。如果您需要更多信息，请随时通过 contact@gslstudios.com 与我们联系。但我很高兴听到没有任何故障可抱怨。亲切的问候。
