Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Interval Task Tracker
Read full descriptionHide full description
There are so many repeating tasks, which are not necessary to be done with strictly fixed interval, but you may want to know when to do next after your last run. For example, replacing the insecticide in the closet every 3 months, or clean up your tools after using 10 days, etc, etc… For such tasks, the standard Reminder app has repeated notification, but you may feel it too strict. If you feel so, this app will be suitable as it manages your repeating tasks in a somewhat loose manner. This app notifies you to do your repeating tasks when it passed the planned date. Unlike repeated notifications of the standard Reminder which automatically notifies you with fixed intervals, this app never starts the interval countdown until the task is actually executed, and when you finish the task, countdown of the interval starts, and the app will notify you when the next planned date for the task comes. The features of this app are as follows; 1. You can see the number of days remaining until the next run date of the registered task at a glance. 2. App prompts the notification to run when the task execution date comes. 3. Tasks that are past the scheduled date of execution are clearly indicated in the task list. 4. App shows you the number of tasks past the scheduled date with icon badge. 5. Just swipe the task in the task list, when you finish that task. 6. App tells you to run it again when the interval you set has elapsed since the day you did the task. Manage the tasks with strict deadlines by the standard Reminder app, and manage the repeating tasks with loose deadlines by this app!

Verdict
The clearest difference is price: 解方程计算器 at Free against Interval Task Tracker's $1.99. 解方程计算器 also leads on update cadence (every 3 months vs every 8 months). Interval Task Tracker's advantage is in-app purchases (none vs 4). On ads, device support and iOS requirement there is nothing between them.
