### 3/5 — 実に惜しい！！据え置きと取り崩しは素晴らしいが…

*2025-01-22, version 1.0*

全体的に金額と年数の上限が小さいので、この点を改良していただけたら新NISA神アプリです。早期退職や老後資産を考えると、毎月積立30万・投資資産額は億・取り崩し50年の設定は欲しいところです。

### 5/5 — めちゃくちゃ良いアプリ！

*2024-09-22, version 1.0*

私の望んでいたアプリそのものです！積立金額の上限を20万に増やして、取崩し年数を40年に延ばしていただけたら完璧です。あと、5個くらいのシュミレーション結果を保存できたら何も言うことはありません。NISA、iDeCoの投資プランを練るのに重宝する素晴らしいアプリです。仮にFIRE出来たとして、4%ルール以外の取崩しプランの計算にも役立ちます。お勧めアプリです！
