人生の午後3時
Read full descriptionHide full description
一生を一日(24時間)にたとえると今が何時にあたるかを時計で表すアプリです。かつてのユングの「無意識の世界」の邦題「人生の午後3時」をヒントにして作りました。時刻と年令の関係が不思議に一致しているように感じられます。 他に、「生まれて何日」「平均寿命まで何日」「厄年まで何年」等自動で計算してくれます。数字を見てしみじみしてください。 おまけとして、3つ自分で決めた日(目標の日)を入力できるようになっています。ご利用ください。 Appストアで機能を追加していただくと、年齢に合わせた平均寿命で計算できるようになります、例えば50歳男子は平均寿命83歳で計算され表示されます。
RedoCalc
Read full descriptionHide full description
This is a calculator for people who only use it for simple calculations, such as adding up receipts or calculating the cost of a meal split between several people, but who are always worried about whether the input was correct. As it is a simple calculator, the only operations it can perform are - Four arithmetic operations (addition, subtraction, multiplication, division) - Percentage calculations (including calculations such as consumption tax using percentages) . The results are displayed as numbers with a digit symbol. There is no complicated exponential display. The calculation proceeds in the order of the keys you enter. There is no priority for multiplication or division. The formulas you enter are displayed in order in the upper area as a history. If you tap the white part, it will turn yellow and you will be able to modify that part. (You can modify not only numbers, but also arithmetic symbols such as + and ×.) If you tap “=”, the expressions from the first line to the last line will be recalculated. The result will be automatically copied, so you can switch to other apps and paste the value there.

Verdict
The clearest difference is in-app purchases: RedoCalc at none against 人生の午後3時's 1. RedoCalc also leads on update cadence (every 3 days vs every 2 months). 人生の午後3時's advantage is ads (none vs shown) and iOS requirement (9.1 vs 18.0). On price and device support there is nothing between them.
