-Function List- 1: Record Daimoku This is a basic function of this app, so I created this to record properly in offline. This app records your Daimoku by Stopwatch, but it is enable to count whenever you open other apps or when your device went sleep until you force termination. When it counting, icon badge will show up on Chant tab. We can use our devices and apps but not always. No worry, you can record it later. 2: Prayers Management You can freely add, edit, and delete your own prayers, and see them always even while chanting. Every prayers has useful attributes such as start date, target end date, category, favorite flag, you can filter by category, and you can change those attributes with your swipe action. When I had managed my prayers by paper book, wrote black line and completed date when completed. You can do it the same thing with this app, and you can see completed and canceled prayers as well as On-Going prayers. I tried not to lose the usefulness of the way of paper. Each prayers can be managed by the status of "On-Going", "Completed", and "Canceled" 3: Target Management When you see, touch, meet, or attend in a meeting, you will resolve things such as 1 hour Daimoku everyday. Or maybe you will start your challenge towards next coming anniversary day. You can use this "Target Management" function to manage your challenge. By checking the actual result of your Daimoku from start date and end date on the beautiful graph, you can know your progress and position against to your target. Of course we will have multiple targets, and this app can manage multiple targets. After complete one target, you can add next one and check the progress. Also you can check back your past results and past targets, because this app manage targets by adding to a target list. 4: Trend Analysis In addition to Target Management, you can check your Daimoku records of last 1 week by daily, last 1 month by daily, and 1 year by monthly. And, you can also check average by weekday, so you will see that "Average of Friday is little behind compared with other weekday" Also, D-Rec has a calendar function, and some anniversaries are set as default. I know that we have our own anniversaries by region and organization. No worry, you can add your own anniversaries on the calendar and target it. By setting some your own anniversaries, you can set the target. 5: Dimoku Amount Calculation This app basically manage your Daimoku by second unit, however, you can also check Daimoku amount at the same time, if you register your Daimoku amount per minute in advance. Is if really 1,000 Daimoku by 20 minutes? Pace is different by individuals, so register your pace. 6: Remind Function I think you used to chant Daimoku everyday and already that's a part of your life. But if you set the remind time, app will tell you "It is the time to chant Daimoku." 7: Calendar Function (Anniversary Register Function) You can check your chanting date and time by calendar. Some anniversaries which are on public home page of SIG, are default set. In addition, you may have your own anniversaries for your local region, and organizations. Yes, you can add any anniversaries on this calendar. It is good to set some anniversaries and set target toward some your anniversaries. 8: language is available in Japanese and English I would like overseas SGI members to use this app, so I created this in both Japanese and English. If you change your iOS device language, the app language change.
