[Dots] ■ Photo feature “Group Dots” “Group Dots” is a photo feature where you and your close friends create one best post together. By sending one selfie a day to each other among close friends, a collage is automatically created. Each collage is stamped with the date and saved as a lasting memory. ■ A place where you can show your true self On social media until now, even good posts could be seen as bragging or self-assertion, so it was hard to post. Dots is a feature where you create one best post together as a close group. Not just by yourself—let’s create the best post together. ■ A place where you can learn who your real friends are With Dots, you can discover a side of your friends you didn’t know. They may be more fun, more interesting, or more shy than you thought. By showing your true self, your friends will show theirs too. ■ The more you use it, the closer you become The more you use Dots, the closer your friend group becomes. That’s because you build a world that only you know, and only you share. With daily posts, create your own world that no one else can enter. ■ Discover a new way to express yourself No editing needed. What matters is not a scene anyone can capture, but the fact that I am here. My own today. With Dots, you can share your everyday life as self-expression. Show your true self only to your closest friends. ■ Keep memories with your children Preserve your growing child together with your own aging self. When your child becomes an adult, look back at how you looked when you were young and laugh together. With Dots, you can keep memories of you and your child forever. ■ Keep memories with your family Save memories with your parents, grandparents, and family who live far away. Send each other selfies every day, and even without messages, let them know you’re doing well. Even a simple photo will make your family very happy when it comes from you. [Text Call] ■ Convenient, new group communication Text Call is a convenient, new group communication tool that feels like a phone call, but with text. Open the app and start a call, and people can respond right away. When they do, a real-time conversation begins, so you can communicate with a call-like feeling through text. Free to use. ■ Call-like communication even where calls are difficult On trains, when family is at home, late at night—there are many times when it’s hard to make calls. With Text Call, you can call out to a group like a phone call and exchange real-time text, so you can communicate like a call even in places where normal calls are difficult. ■ Messages people notice When you send a message and it goes unnoticed, you used to have no choice but to make a phone call. With Text Call, you can reach them in a call-like way through text, so you can get their attention without putting pressure on them. ■ No call-related stress In urgent moments, you may want to call, but calls can be nerve-wracking and mentally difficult. With Text Call, you can communicate in a call-like way through text, making communication easy and stress-free. ■ Fast replies It’s common for replies to suddenly stop while you’re chatting. With Text Call, you and the other person exchange messages in real time, so replies come back immediately. ■ Feelings come across With messaging apps, misunderstandings and miscommunication often happen. With Text Call, feelings come through even though it’s text. * Jiffcy is a popular social app. Have fun using it with your friends. * Jiffcy is a social app to use together with LINE, Messenger, Mitene, and mixi. * Jiffcy is an app to use with your boyfriend/girlfriend, lover, best friends, friends, and family, together with TikTok, YouTube, BeReal, Popopo, and Instagram. * PCT international patent acquired For questions or feedback, please contact the official Jiffcy account @Jiffcy or email mail@anaguma.co.jp.

MustPost|マストポスト ◆MustPostってなに?◆ 毎日お題が来るSNS! ◆毎日ランダムな時間にみんな一斉に「今日のお題」が届く◆ 友達と「今日のお題〇〇だって!どうやって撮る?!」ってわちゃわちゃして、撮って、投稿して、マスポ内でみんなとリアクションし合う。それだけ。 何もなかった日も、映えない日も、自信ない日も「お題」があるから投稿できる。 友達から「マスポボタン」が来るから投稿できる。 投稿するのは、特別な日だけじゃなくていい。 MustPostがあれば、毎日が少し楽しみに変わる。 ◆こんな人、使ってみて◆ ・毎日同じ日々の繰り返し ・最近SNSに投稿することがない ・なんか退屈 そんなみんなの毎日をMustPostがブチアゲる。 ◆使い方◆ 1. インストールして登録 2. お題を確認 3. お題に関する写真を撮って友達とシェア 4. 好きな投稿にリアクション! 5. 投稿してない友達には「マスポボタン」を送って投稿させよう! これだけ! ◆マスポを作った背景 家と学校とバイトの往復で退屈な毎日の繰り返し。 つまんないからとりまSNS見るけど、毎日同じ生活すぎて投稿するものがない。だから今日も人の投稿見るけど、見る度病んで時間が終わる。 大切な学生生活なのに、私も含め周りの友達がみんなこんな感じだった経験から、アプリ内はもちろん、リアルの世界でも、投稿してブチアガれるSNSを作った!! ◆テストリリースに協力してくれたみんなへ◆ みんなのおかげで今日のリリースを迎えられました。 これからもっと楽しんでくれると嬉しいです! みんなのユーザーIDに協力してくれた証があるから見てみてね!! ◆マスポを使ってくれるみんなへ◆ MustPostを見つけてくれてありがとう!! これからもみんながめっちゃ楽しめるように、進化し続けるので、アドバイスや質問あったらLINEオープンチャットに送ってください!マスポの中の人(私)が直接見て返信します! & MustPostの略し方をみんなに決めてほしい!!! 「マスポ?」「マスポス?」... 呼びやすいニックネームをつけてくれたら嬉しいです!!!!!!!!!!
