See your course average, recent scores, and distance to the next letter grade. Grade rulers put every course on the same 60 to 100 scale.

Courses

See how the number adds up.

Open assignments and category breakdowns. Switch quarters and semesters, search your work, and review grading rules, weights, multipliers, and excluded assignments.

What if

Try the next score.

Change a score, try a retake, leave out an assignment, or add future work. Choose its category, reporting term, and multiplier. Save scenarios and come back to them.

Goals

Know the score you need.

Set a target for your next assignment or a final worth a share of your semester. Tally rounds required scores up to the next hundredth and tells you when a target is out of reach.

Refreshes every two minutes

Connect once in the app. New scores arrive while Tally runs. Closing the window keeps it running; Quit Tally stops it.

Your workspace, saved

Keep scenarios and custom rules, export a backup, or explore sample grades. Manage your connection in Settings.

Your grades stay on your Mac.

Good to know.

Does Tally work with every PowerSchool school?

This version supports Wayland PowerSchool. Other districts can use different sign-in systems and grading rules.

How does Tally calculate grades?

Tally uses assignment scores, category weights, reporting-term formulas, multipliers, extra credit, and exclusions. It keeps full precision until the result is displayed. Courses without confirmed rules are marked as estimates; grades without underlying scores are labeled separately.

Why might Tally differ from PowerSchool?

Hidden scores, unpublished rules, and teacher overrides can change the official result. The app lets you inspect its rules and enter category weights by hand. Letter grades use a standard scale that may differ from your school’s. PowerSchool is always the official grade record.

Will I need to sign in every time?

Tally saves the school session on your Mac and restores it when you reopen the app. Your school can still expire the session. If it does, choose Reconnect and sign in again. Cached grades remain available between updates.

Do predictions change my real grades?

No. Changed scores, added assignments, and saved scenarios stay in Tally. They do not write to PowerSchool.

Can I look around before signing in?

Yes. Choose sample grades in the app’s welcome screen or Settings. They are made-up courses. You can also try the interactive preview on this page.

What can I do with my saved data?

In Settings, export a JSON backup of grades and scenarios. Reset scenarios and manual rules while staying connected, or disconnect to clear your school session and cached grades.

Does it work on Windows, iPhone, or an Intel Mac?

The current download is for Apple silicon Macs with macOS 14 or later. Windows, Intel Mac, iPhone, and Android builds are not available.
