Growave: Loyalty & Wishlist

It is a very great app.
Whenever I had any issues, I was able to contact the support team and they were able to resolve all issues quickly.
Also, I used to use multiple apps, but thanks to this app I was able to consolidate them into one, which saved me a lot of money and I am very happy with it.

日本の方向けにも。
複数の機能を1個に集約でき大幅な節約ができます。
また、複数言語への対応もしっかりしているので安心して利用できると思います。
ただ、サポートは英語のみなのでそこだけ注意が必要です。
