Pictove

A picture worth solving.

Draw a little picture. Turn it into real number clues. Check for one answer, try solving it, and give someone a printed puzzle.

iPhone & iPad · iOS 17+ · One upfront purchase

Prepared for App Store submission. Availability begins after Apple approval.

Finish the puzzle you meant to make.

Fill or erase pixels, import a PNG/JPEG photo, flip, rotate or invert. Mark explicit given cells, then run the bounded solver. It reports one solution, multiple witnessed solutions, or an inconclusive search.

Test-solve with fill and × tools. Check marked cells against your artwork, reveal a selected cell, undo and restart. Progress and editable pictures stay in a local library.

Print something useful.

Create A4 or US Letter books with up to 20 selected pictures, one puzzle per page. A separate answer book follows the same order. The current picture also exports puzzle/answer PNGs, a vector puzzle SVG and a restorable JSON project. Preview the actual PDFs before native sharing.

Screens show optional original geometric examples available inside Pictove. First launch starts with an empty library.

Support

Email maga40@naver.com with Pictove, version and a description of the issue. Do not include private artwork unless needed and you want to share it.

5–20 cells on each axis, monochrome. Up to40 local projects.
PNG/JPEG up to 10 MiB and 20 megapixels. Image conversion is centered aspect-fit on white. Only cells are retained; the original image is not in backups.
Validation is bounded at 20,000 search nodes or 3 seconds. A unique result does not guarantee logical-only/no-guess solving or measure difficulty. A resolving given is chosen from two differing solutions, not a minimum-hint set.
Empty lines use0 clues. Given cells have a circle; a × given is blank. Every test-solve cell needs fill or × for completion.
JSON up to 1 MiB restores title, instructions, cells, givens and progress into a new ID. Keep external copies before uninstalling or deleting.
PDF books contain only selected pictures. PNG, SVG and JSON contain the current picture. SVG text appearance depends on the receiving app. No printer, publishing platform or third-party software guarantee.

Privacy policy

Effective October 4, 2026. Gobling Company does not collect data through Pictove. The app has no developer network requests, accounts, ads, analytics, tracking or third-party SDKs.

Artwork, givens, titles, instructions and progress are stored locally on your device. Selected files/photos are processed locally; photo originals are not retained. Exported files contain the picture and its project information, so review them before sharing. System file/photo/share services and device backups follow their own provider settings.

Delete a picture to remove its local project and local export folder. Uninstalling removes the app's local data; shared copies and system backups are separate. A support email is voluntary and handled only to respond to your request. Contact maga40@naver.com with privacy questions.

Terms

One purchase includes all current tools. Pictove is a creation and printing aid. Use only artwork you own or have permission to use. Review clues and outputs before distribution. Validation can be inconclusive; no difficulty, logical-only solving, publishing acceptance or printer compatibility guarantee is made.

Apple manages App Store purchases and refund policies. Pictove has no online publishing service or bundled commercial puzzle catalog. Keep exported backups before deleting or uninstalling. Apple's standard application license applies.
