Hoopside is a cross-stitch tracker for iPhone. Import a PDF chart, mark stitches as you go, and keep a list of the floss you already own.
The included chart
Evening Peony comes with the app. You can mark it without importing a pattern and without buying the unlock.
Free trial
On the purchase screen, tap Start 14-day free trial. That is a free App Store item called 14-day Trial. Nothing is charged, and it does not turn into a subscription. The 14 days start when you tap Start and stay tied to your Apple ID, so deleting the app does not start the trial over.
While the trial is running you can mark every chart. When it ends, your charts and progress stay on the phone and you can still look at them. Marking an imported chart then needs the one-time unlock. Evening Peony can still be marked.
Full unlock
Full Unlock is a one-time purchase. There is no subscription and no advertising. Family Sharing is on, so people in your Family Sharing group can use the same unlock.
Open the purchase screen from Settings, or by trying to mark a chart that is locked. Restore Purchases is on that screen and in Settings. Use the Apple ID that paid. If Apple refunds the purchase, marking locks again. Your charts and marks stay on the device.
Scanning a skein
Scan reads the number printed on a skein band. Hold the band flat, then confirm the number before it joins your stash. If the camera is unavailable, choose a photo of the band. The number is recognized on the phone.
