In the age of technology, students continue to carry around a school diary, planner, or an agenda to record their classes, assignment, tasks, and reminders.

Sigma Planner is the perfect companion app for your school life that will help you keep track of your courses and allow you to add your weekly assignments and tasks into your schedule with ease. With Sigma Planner, you will no longer need to carry your school planner; simply pull out your phone, and everything will be available, right at your finger tips.

Track your courses and assignments with ease. Add and organize the app just the way you need; Sigma Planner supports period, time, and block schedules for students all around the world.

You shouldn't need to clear or clutter your timetable whenever you have a new schedule. Sigma Planner offers the ability to organize your courses by semesters, which allows you organize your different timetables all within the app, with the option to view your older schedules or to hide them with a simple toggle.

Sigma Planner is built to be flexible and just for you. Choose between the light or dark theme; change the push notification times, or customize your period or block schedules, all within the app.

Tasks should be easy to find. With filters, you'll never lose a task. Sigma Planner also includes upcoming tasks list for easier tracking of your tasks that are soon overdue and displays everything that you have that are already overdue.

Want to find out what class you have next, or tasks that are due soon, without opening the app? Sigma Planner offers a Today widget that displays your classes for the day and your upcoming tasks. Simply enable the widget in the Today extension, and voilà.

The interface is clean, simple, and intuitive; and adaptive for the iPad for those who like to manage their school through a bigger screen. Sigma Planner even comes with over 50 custom icons for your courses, all on top of the customization you get with the app.

Want to protect your course or school information? Don't worry, Sigma Planner includes the ability to lock the app with a passcode, and Touch ID or Face ID on available devices. It just works!

Awesome app


Note: I got this app while it was free. I would have paid for this app if I knew about it before it was free! This app is definitely worth $5! Even though I think it was only 1 or 2. The app is pretty much a digital planner and it works perfectly, I would suggest this to anyone who has an iPhone and needs a planner! But if you are using it for school, you should only purchase this app if you can use your phone in class!

Great app for a free one


I usually don’t download free apps, because I naturally assume they’re inferior, but after downloading quite a few inferior fee-based apps, I am pleasantly surprised with the functionality of Sigma Plan. Of course, it would be nice to have sub tasks and maybe a note taking area, but for free, this app is ideal. Thank you.

I love the app, but


This app would be perfect for managing my postgraduate assignments. It really has everything: an intuitive layout, reminders, calendar, etc. However, it doesn’t sync across iCloud to multiple devices, and so I’m forced to re-enter everything. I don’t think I’ll continue to use this app until iCloud syncing is an option.
