The author planned this app for the education of morality. It means studying Two Customs. (Custom1);;The first one is thanking Father God in Heaven for looking tab on the plots and evildoing by the Wicked people and Not for letting them achieve the plots and evildoing. (Custom2);;The second one is Not Fearing the plots and evildoing by the Wicked people But Fearing disobeying the Commandments of Father God in Heaven. This app uses the form of Action Game in order for you guys to study the two customs. ****the Story of this Game;; In the game, "Yassun", a New Hope, who survived the human disasters in Japan and arrived at NYC as a refugee. Yassun has looked for a new job in NYC in order to earn the money for living. But even in the game, the Wicked people plots and tries to trap others in order to oppress others. Yassun doesn't have any armers nor any weapons. Yassun just escapes from the Wicked people. But by the Grace of Father God in Heaven, the Wicked people themselves were captured by the traps which they set. Yassun has some of job interviews. Yassun makes some of portfolios every time after he got job interviews. The author of this app hope you guys raise the two customs in your souls and in your bodies. **"Settings Sound" function;; You can turn on or turn off the sound effects and BGM at "YassunPsalms" on "Settings" app. You can jump to the Settings->YassunPsalms when you touch the Setting icon on this app. **"Tip the Author" function;; This app is basically for free. When you completed Each round, you will See "In-App Purchase" button near the Left Bottom of screen  and then you will be able to Tip the Author of this app. "Tipping" is Not forced, you can tip ONLY WHEN you'd like to tip. "In-App Purchase" is implemented by the latest "Store Kit2" which was released in 2021 for the first time. ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | TipThreeDollarNinetyNineCents | $3.99 | one-time | | TipFourDollarNinetyNineCents | $4.99 | one-time | | TipNineDollarNinetyNineCents | $9.99 | one-time | ## Version history (last 5 releases) ### 2022.0604.0459PM — 2022-06-04 Code ReFactoring Version; so it's supposed Not to change the External Behavior. But this version includes some of small changes. 1of3;Changed the Basic Screen Size from 5.5inch to 4.7inch 'cause  Changing the Screen Size from Smaller to Larger is Physically Easier than  Pushing the Larger things into the Smaller Screen and 'cause 4.7inch is the Smallest Screen Size in the current iPhone LineUp. 2of3;Made the Cursor Keys Larger. 3of3;Moved the Cursor Keys from Right to Left. 4of4;Changed the BackGround Color to the Sky Blue at the SideView stage  going up the building with some of the stairs. ### 2022.0601.0526PM — 2022-06-01 Bug Fix of "Settings Sound" function;; the internal file "Settings.Bundle" does Never create the specified keys such as "turnOnSoundBGM" and "turnOnSoundEffects". the specified keys are created ONLY after you changed the value of the specified keys at "YassunPsalms" on "Settings" app Manually. Now Fixed the bug Not by "Settings.Bundle" file But by Programatically. So That the specified keys are created and are Set as "TRUE" When this app is installed and first launched. ### 2022.0416.1230AM — 2022-04-16 This is a Make Good Sense Version against the Non-Existence Problem of $4.99 in In-App Purchase. We Modified the productID of $4.99 from "com.yassun.YassunPsalms.consumable.TipFourDollarNinetyNineCents" to " com.yassun.YassunPsalms.consumable.TipFourDollarNinetyNineCents2" in the "Products.plist" file and "Products.storekit file". The Test Result of TestFlight shows the Existence of $4.99. ************************** This was Crazy thing 'cause After submitted binary code including Products.plist and Products.storekit files, Even if the productID in AppStoreConnect's "In-App Purchases" features Had Changed(??), the productID of Products.plist and Products.storekit files don't Need to Change after submitted binary code. We Thought Products.plist and Products.storekit files are Only for Local test, But the productID in Products.plist and Products.storekit files Were Needed to be the same as the productID in AppStoreConnect's "In-App Purchases". So since they can't modify the productID in AppStoreConnect's "In-App Purchases" features, We modified the productID in Products.plist and Products.storekit files and will submit this new binary code. This is the Make Good Sense Version. ******************** Why is this Crazy?? GUI such as AppStoreConnect's "In-App Purchases" features is created in order to makes development and management easily. so if something is needed to change, it needs Not to be on binary code including Products.plist and Product.storekit files, it Needs to be on GUI such as AppStoreConnect's "In-App Purchases" features. Of Course, I didn't hardcode productID into Swift source code in accordance with the Separation Principle of Data and Code in Information Technology. The existence of Products.plist and Product.storekit files themselves shows the Separation Principle of Data and Code in Information Technology. And we don't hope to ReUse of AppleID of In-App Purchase Product  but we hope we Can ReUse ProductID of In-App Purchase Product in AppStoreConnect's "In-App Purchases" features in order to avoid changing the ProductID of Products.plist and Product.storekit files after submitted binary code. ### 2022.0413.0523PM — 2022-04-14 the Problem about the In-App Purchase Product Display Description Fixed. ### 2022.0412.1207PM — 2022-04-12 BandAid Version against Non-Existence of $4.99 Problem. this version might avoid crashing of this app even if you touched $9.99 button. The problem is below. Now We have Three In-App Purchase Products, $3.99, $4.99 and $9.99. this App recognizes as there are three IAP Products, but Now $4.99 is Not received, so when you touched $4.99 button, this App shows $9.99, and when you touched $9.99 button, this App crashes. ## Apps similar to YassunPsalms | App | Rating | Price | Category | | --- | --- | --- | --- | | [Cryptocurrency For Beginners](https://appshunter.io/ios/app/cryptocurrency-for-beginners/id1582504036) | 4.8 (472) | Free | Education | | [QuizGenie AI: Writer & Chatbot](https://appshunter.io/ios/app/quizgenie-ai-writer-and-chatbot/id1659302154) | 4.5 (19) | Free | Education | | [Japanese Flashcards – Manabi](https://appshunter.io/ios/app/japanese-flashcards-manabi/id1180710626) | 4.1 (32) | Free | Education | | [PockEmul](https://appshunter.io/ios/app/pockemul/id1550150838) | 4.3 (11) | Free | Education | | [BugFine - Catch and Record](https://appshunter.io/ios/app/bugfine-catch-and-record/id1625380389) | — | Free | Education | | [Daily Dose of Greek](https://appshunter.io/ios/app/daily-dose-of-greek/id1346478691) | 4.8 (109) | Free | Education | ## More apps by Yasushi Obata - [YassunCallUpNotice](https://appshunter.io/ios/app/yassuncallupnotice/id1621617154) - [YassunBitterness](https://appshunter.io/ios/app/yassunbitterness/id1624704495) - [PeterJohn ThreeDim](https://appshunter.io/ios/app/peterjohn-threedim/id1632372110) - [PeterJohn NumPy](https://appshunter.io/ios/app/peterjohn-numpy/id1662896316) - [PeterJohn NumPy Matplotlib](https://appshunter.io/ios/app/peterjohn-numpy-matplotlib/id6471342492) All apps by Yasushi Obata: https://appshunter.io/developer/899977114 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
