From measured ball to checked map.

Create a project from the real circumference

In Atlas or Projects, enter the circumference of the finished mari in millimeters or inches, choose S4, S6, S8, S10, C8, or C10, select a colorway, and save the project. The app converts entered measurements internally and shows calculated diameter, equal intervals, centers, and guide circles.

Supported circumferences are 25–2,000 mm. Measure around the widest part with a narrow paper strip, keep it flat, and repeat the check through several planes. Do not rely on a nominal foam ball or core size.

Read the simple or combination map

N and S are opposite poles. E1 through E4, E6, E8, or E10 follow the equator in wrapping order for the selected division. Solid guide lines face you; dashed lines continue behind the sphere. Drag horizontally or use the accessibility actions to rotate the map, and use the rotate control for an automatic turn.

C8 shows 6 main centers and 9 guide circles. C10 shows 12 main centers and 15 guide circles; its finished framework has no equator.

The globe is ideal reference geometry, not evidence that the physical mari is round or accurately marked.

Complete the physical measurement audit

Record four pole-to-pole routes between the same poles, each through a different plane. Then record every neighboring base interval, including the closing interval back to E1. For C8 or C10, also record every neighboring main-center edge: 12 or 30 readings. Finally confirm all 3 or 6 named opposite-center pairs on the physical mari. Temari Atlas shows the spread between pole routes and each signed deviation from its target.

Choose a tolerance from ±1 to ±3 mm. “Incomplete” means one or more required measurements or confirmations are missing. “Outliers” means at least one reading falls outside tolerance. “Passing” means every required check passes; it is not a guarantee of the finished craft result.

Use the workshop checklist

The project workshop follows the marking sequence from fixing the north pole through establishing the base division, locating combination centers when applicable, wrapping guide circles, and tacking intersections. Progress and notes are saved with the project.

Changing the circumference or division changes every target. Temari Atlas asks before clearing stale audit readings and workshop progress. Duplicate a project first if you need to preserve the original record.

Export and print the 3 mm marking strip

Open a project’s marking-strip exporter and choose US Letter or A4. The app shows the generated PDF before you print or share it. The PDF contains a 1:1, 3 mm-wide strip, labeled targets, combination setup marks when needed, a 50 mm calibration line, and an E1-to-close assembly check. Longer circumferences are tiled with a 10 mm overlap and matching A/B registration crosshairs.

Print every page at 100% or Actual Size with fit-to-page and scaling disabled. Measure the 50 mm calibration line before cutting. For a tiled strip, overlap adjacent pages and align both A and B crosshairs before taping, then verify the complete E1-to-close length against the physical mari.

For C10, the exact spherical adjacent-center target acos(1/√5) ÷ 2π × circumference is primary. The familiar 1/6 + 1/100 value is shown only as a traditional secondary reference. Follow one chosen method consistently rather than mixing targets.

If the PDF prints at the wrong size

Confirm the selected paper size matches the paper loaded, turn off “Fit,” “Scale to fit,” borderless enlargement, and other automatic scaling, then print one inexpensive test page. Printer and Files-provider preview screens can use different labels; the physical 50 mm line is the deciding check.

If adjacent tiles do not align, verify that every page was printed with the same orientation and scale. Never compensate by stretching one page independently.

Back up and restore projects

Projects are stored locally in the app. Use the Projects screen to share a JSON backup to a location you choose. Importing a valid Temari Atlas backup merges records by project identity and keeps the more recently edited record. Keep an unchanged copy of the backup before manually editing JSON.

If import fails, confirm that the file is a Temari Atlas JSON backup, is no larger than 10 MB, and has not been truncated or converted by another app. A backup may contain project names, notes, measurements, colors, and progress, so store and share it with the same care as the underlying craft notes.

Archive or delete local work

Archiving hides a project from the active list without deleting it. Deleting removes that project from Temari Atlas local storage. Removing the app may remove all local projects, subject to Apple device backup and restore behavior. Export a JSON backup first if you may need the work later.

Purchases

Temari Atlas is planned as a paid download with no subscription or in-app purchase. The final one-time price remains gated on physical C8/C10 validation. There is no in-app restore button. Use the same Apple Account in the App Store to download a prior purchase again. Apple handles payment, refunds, regional pricing, and Family Sharing availability.

Accessibility

Temari Atlas uses system text styles, labeled controls, a text legend for map structure, and named actions for turning and tilting the globe. The Reduce Motion setting prevents automatic globe rotation.

The sphere remains a spatial visual reference, and some relationships may be easier to inspect visually. If text, VoiceOver, switch access, contrast, or another interaction prevents you from completing a workflow, contact support with the screen and task involved.

Contact support

Email mannykin333@gmail.com. Include Temari Atlas version 1.0, your iPhone or iPad model, iOS or iPadOS version, selected division and units, and the exact step where the problem occurred. For PDF issues, include paper size, printer model, and the measured calibration-line length.

Do not send passwords, payment details, or a project backup unless support specifically asks for it and you have reviewed its notes and measurements.

Privacy

Temari Atlas does not collect or transmit project content, measurements, exported PDFs, or backup files. Read the Temari Atlas privacy policy for complete details, including user-directed sharing and device backups.
