A confusing app. The app's .apk shows up in the dumped files of the Evangelion-themed SH-06D Docomo phone (https://archive.org/details/system_20200521), but doesn't work because the .apk is missing everything it needs to work. The app itself was also released to the Play Store at some point for some reason. The app was released as part of the "SH-06D NERV PROJECT". The app runs on Unity.

An English version of Homura TPS. The app costed $7.64. The app was removed sometime in 2013. There are only two pages as of right now that I can find even mention the app. According to scraped info from Soft112, the app included voicelines by Homura re-recorded in English.

Platform: Android (via au Market)

The app costed ￥390. The app claims to have all three Madoka Magica TPS apps in one, and all voice lines exclusively re-recorded. There may have been a PC port as suggested by page metadata, although it is very unclear if this is true ("あの人気アニメ「魔法少女まどか☆マギカ」の本格TPSがお得なパックで登場！！【Android,PCのみ閲覧可能】").

Name: Steins;Gate Battery Manager
Platform: Android
Release Date: December 27, 2011
Developer: ID corp.
Publisher: 5pb/Mages
A battery manager featuring Steins;Gate characters. Kurisu's was uploaded by someone I contacted in March 2023 (torrent; archive.org upload). Finding information about ID Corp. is difficult, so I will explain here so people don't have to go out of their way: ID Corp. was a company founded in April 2010 by video game producer and composer Hajime Kanasugi. Kanasugi was a former director of Dwango, explaining why Mages hired ID Corp; ID Corp disappeared after December 2012, though Kanasugi is still around. From statistics I've read (possibly unreliable), anywhere from 10-100 people have downloaded Moeka Battery Manager, so the rest of the apps are going to be extremely difficult to find.

A Flash wallpaper promised to buyers of the book Steins;Gate: True Memories of Mutual Love (Steins;Gate 相思相愛のトゥルーメモリーズ) (notably as well as several other books; it was part of デレ期ｋｔｋｒ！キャンペーン). The book's jacket claims the wallpaper was available from the book's release (October 2011) to June 2012. The wallpaper was accessible via a QR code in the book's jacket. Apparently, you could only register for the wallpaper until January 31, 2012. The website it was on was connected to Animate Mobile (redirected to it from 2009-2014) and Pokedora, a website operated by Animate (redirected to it from 2014-2016).

An early example of Live2D. The 148apps page actually shows even more lost Haruhi apps which I'm too lazy to list, since they've all got similar info. The game was released for a limited period of time and was removed on August 31, 2011.

Name: ベアトリーチェからの挑戦状 (A Challenge from Beatrice)
Platform: Web (umine.co)
Release Date: October 27, 2010-December 28, 2010
Production: Unknown
Publisher: Alchemist Co. Ltd.
A promotional campaign to promote the release of Umineko PS3. One question was released per week, in total there were 10 questions plus one last questions (11 in total). Its segment in the umine.co website remains mostly lost although most images used for the promotion were archived. Some stages had special prizes in the form of an Adobe Flash file, but I'm not sure what was in these .swf files. I am working on a recreation of the website but I really don't think it can be completed.
Edit September 8, 2024: All of the prizes have been found! So the only thing missing would be certain files, the code to the pages themselves, as well as the character-specific emails received at the end of the campaign.
