Action Compare

Action Compare is an iPhone app that converts user-entered activity costs and times to a common period for comparison. For each activity, users can enter a name, necessity level, pleasure or discomfort level, cost, time, and recurrence interval. Values are normalized to a day, week, month, or year and shown in a comparison list. Multiple activities can be compared as alternatives or totaled as one group. Key features • Normalize money and time to a shared period • Compare alternatives or total a group of activities • Sort by amount, time, necessity, pleasure, or avoided discomfort • Save frequently used comparison and total groups • View stacked cost and time charts across recorded periods • See money share and time share • Exclude a cumulative range of necessity levels from charts • Switch chart ranges from one month to 30 years • Export and restore a JSON backup • Use the app in English or Japanese The guided entry flow asks one question at a time, and a first-use guide explains the main controls. No account is required. Entries normally stay on the device. The app contains no ads, analytics, tracking, third-party SDKs, or network communication. Actions, recording periods, saved groups, and settings can be exported manually as a JSON backup and imported later. You can customize the displayed money unit and its position. Existing values are not converted between currencies. Action Compare is an organization and visualization tool based on values entered by the user; it does not provide financial, investment, medical, or other professional advice.
