### 3/5 — 続けて少数を入れる場合

*2025-01-03, version 2.0.0*

少数を計算する場合、例えば0.3 + 0.5を入れる場合0を省略して.3+.5でも今まで計算できていたと思いますが、このバージョンでは最初の数字入力は省略できますが、２個目の少数では0.5のようにしっかり0.を最初に入れないと計算できませんね。修正希望です。

### 2/5 — アップデート後

*2024-12-11, version 2.0.0*

ずっと使わせてもらってたのですが、老眼には数字が小さくて見づらいです。
あと、設定から色設定のボタンパターンを変えるとデフォルト？に戻せないんでしょうか？

### 1/5 — 縦表示になった

*2024-12-03, version 2.0.0*

リニューアルしたのは良いけど、iPadで横表示だったのが、縦表示になってしまった。使いにくいのですが、設定で横表示に出来ないものでしょうか？

### 4/5 — 早くiOS 14に対応してほしい

*2020-09-25, version 1.2*

iOS 14で文字化けして使い物にならないので早く対応してください
