JVH Puzzle

Version 1.15 introduces a new sorting option, improvements to the Groups section, and more accurate time statistics, while continuing the development of social and collection features.

What's new and improved:

• New sorting option: Release Year
  You can now sort puzzles by Release Year, with options for Newest first and Oldest first. This sorting option is available in both the Collection view and the Active Puzzles page.
• Groups section improvements
  The Groups section has been updated with a new toolbar to make navigation and discovery easier. You can search for groups by location, set a location when creating a group, and choose whether your group is discoverable through the new Discover feature. Groups will continue to evolve as additional functionality is introduced in future updates.
• Improved time statistics
  Puzzle time statistics now correctly include manually entered completion times. Previously, statistics only used the calculated duration (start time – end time – pauses), which could cause incorrect totals when a manual time was entered. Statistics now use the effective completion time, so totals and averages match the times shown for individual puzzles.
• Combo box add fix
  Fixed an issue where adding puzzles from combo boxes (for example, box 19004) could stop after the first duplicate warning. Duplicate puzzles are now handled one-by-one; choosing Add anyway correctly steps through all duplicates, preventing partially added combo boxes and improving navigation while handling duplicates.
• Manual time entry improvement
  Manual time entry has been improved. You can now type values directly into the time fields, making it faster and easier than only using the +/- controls.

Account Management

• Email address change — Users who signed in with email can now change their email address directly in the app under Settings → Account Management. Added based on user feedback.

Update system improvements

• Update screen issues resolved — Several issues with the in-app update screen have been fixed. The previous automatic version-check was not fully reliable; the update process has been restructured using Remote Config.
• Remote Config — The app now uses Remote Config to control whether an update is optional or required. This allows settings and behaviors to be managed remotely without requiring an immediate new install, leading to more reliable update prompts, faster response to version-related issues, and greater flexibility for future update management.

Timer & completion logic

• Negative time calculation fixed — Adjusting the completion date no longer results in negative time values. Time will never display below 00:00.
• Start/Pause button after completion — The Start/Pause button no longer stays active once a puzzle is marked as completed; it is now properly disabled.
• Incorrect total time when completing later — If a puzzle was finished but marked as completed later, the app could show total elapsed time instead of actual active puzzle time. Timer logic now records only real active puzzle time.
• Extreme time values fixed — In edge cases (e.g. long-open or test sessions), completed puzzles could show unrealistic high times. Time calculations are now more stable and consistent.

Adjust Time on Android

• Adjust Time feature — The Adjust Time feature, previously available only on iOS, is now on Android. You can manually correct puzzle time, account for breaks, or enter a realistic final time if the puzzle was not continuously timed, for greater control and more accurate personal statistics.

Android Update 1.13 focuses on data availability, scanner reliability, and overall consistency within the app. Thanks to major internal improvements and structural refinements, the app is now faster, smarter, and future-proof.

Improvements in this update

• Major internal optimization — Much data is now stored locally instead of being fetched externally. Result: noticeably faster performance, improved stability, and less dependence on external services.
• New internal EAN linking system — The puzzle scanner now first uses our internal EAN-to-article-number database. An external lookup is only used when necessary. This enables faster recognition of new puzzles and makes it possible to add missing codes directly.
• Scan improvements — More reliable and extensive scans thanks to the new internal EAN system.
• Fix for duplicate article numbers — Issues with duplicate article numbering have been resolved. Duplicate puzzles are now recognized more reliably without losing existing detection functionality.
• Advent calendar feature now on Android — The full Advent calendar functionality from iOS has been added. When adding an advent calendar, an explanation screen appears. In your puzzle overview you recognize them by the snowflake ❄️ and can check off boxes per day — just like on iOS.
• "Missing pieces" option when adding — Indicate immediately whether a puzzle has missing pieces. For combo boxes, this is now asked per puzzle — no post-processing needed anymore.
• Ability to submit EAN code — Unknown EAN codes can be shared via Settings → Feedback. This is automatically offered when a scan finds no result. This way we expand the internal database faster.
• Refreshed empty state of the Active page — The empty view now better matches the Collection view for a more consistent visual experience.
• Restructuring of Feedback in Settings — All feedback options are now clearly organized in one section.

Bugfixes

• Timer resume jumped back a few seconds — fixed.
• Theme inconsistency with "Groups" under Next in dark mode — fixed.

Clearer Add Options

In the collection view, the + button now shows three clear choices: Catalog, Scan, and Article Number. Naming is now logical and consistent, and all three add methods are functionally aligned.

Expanded Catalog

Multi-select is now available, allowing you to select multiple puzzles at once. Puzzle information now shows release year instead of elapsed time, which is more relevant while adding puzzles.

Reworked Article Number Feature

The Article Number flow has been fully redesigned and technically aligned with Scan and Catalog for a consistent user experience.

Section Order Customization

You can now set your own section order via Edit → Section Order.

Visual Improvements

• The large puzzle-piece icon shown when starting a puzzle has been removed.
• Active puzzles are now indicated with a subtle orange border.
• This border disappears automatically when the puzzle is completed.
• Piece-count display has been improved.

Improved Timer Logic

If you start a puzzle without a timer, pause and timer options are no longer shown in the active status view.

Refined Rating Screen

In "Rate this puzzle", only the rating section is shown. The full completion sheet no longer appears unnecessarily, making the flow faster and clearer.

Additional Fixes Based on Feedback

• Added a Cancel button in the Edit flow.
• Android back button now works correctly in this flow.
• Fixed an issue where leaving the screen could unintentionally mark a puzzle as completed.
• Completed puzzles can now be reset.

Statistics Fixes

Under Statistics → Collection Distribution, all six categories are now included (such as Loaned and Puzzle Library). No puzzles are missing from statistics anymore.

Update Notification Fix

• The Update button now correctly opens the Play Store.
• The update notification remains visible until the app is actually updated.

Android Back Button Fix

Fixed an issue where, during a specific action, pressing the Android back button could fully close the app.

Rotation Bug Fix

When adding a new puzzle, rotating the device from portrait to landscape could previously interrupt the flow and return you to the home screen. This is now fixed: adding remains active during screen rotation.

Last night, a problem was reported with the barcode scanner. This was immediately investigated and resolved. Version 1.11.1 has been submitted to Google and is currently in review.

What was the problem?

There were three small bugs that prevented the scanner from working correctly:

Too Strict Filtering

The app only accepted barcodes starting with "871012". Other valid barcodes were therefore ignored before a search was performed.

Website Blocked the App

The website recognized the app requests as automated traffic and blocked them. This has been resolved by making the network requests behave like a regular browser.

HTML Was Validated Too Strictly

The parsing of the website content checked too strictly for specific structures, causing correct results to be rejected.

What has been fixed?

• All barcodes are now processed correctly
• The app can reliably retrieve information from the website again
• HTML parsing is robust and accepts valid variations in page structure

Result

The barcode scanner now works again as it does on iOS: barcodes are scanned, the website is consulted, and puzzles are correctly found based on article number or product name.

The update should be available in the Play Store within approximately 72 hours.

Update 1.11 is live on Android! Version 1.11 brings a series of improvements that provide better overview, consistency with iOS, and expanded collection functionality.

New Collection Source: Lent Out

You can now indicate if a puzzle has been lent out. This option has been added in multiple places throughout the app and seamlessly integrates with the existing display.

Better Overview in Your Collection

Sections now show the number of puzzles in clear labels, so you can immediately see how many puzzles are in each section. Additionally, the section header icons have been adjusted to be fully consistent with iOS.

Export Your Collection

Via Settings, you can now export a complete overview of all puzzles in your collection.

Start With or Without Timer

When starting a puzzle, you can now choose whether to begin with a timer or without a timer.

Register Missing Pieces

You can now indicate if a puzzle has missing pieces, how many there are, and add a note about it. The number of missing pieces is immediately visible in your collection.

New Statistic: Piece Distribution

A new statistic has been added that provides insight into the distribution of piece counts in your collection, aligned with standard Jan van Haasteren puzzles.

Improved Search and Database Processing

Previously, puzzles were only retrieved when all fields were completely filled in. Puzzles without a known article number were therefore filtered out and could not be found. This has been adjusted: puzzles without an article number are now also included and can be found by searching by name.

Cleaner Display for Completed Puzzles

The 'Completed' label for finished puzzles has been replaced with a subtle checkmark. This creates a calmer and more modern appearance. The Android version is now visually aligned with iOS.

Rate Your Completed Puzzles

In the detail view of completed puzzles, you can now directly give a rating via 'Rate this puzzle'. This functionality is now also fully aligned with iOS for a consistent experience on both platforms.

Advent Calendar 2025 Correction

The number of puzzles in the Advent Calendar 2025 was not correct in Android. This had already been adjusted in iOS earlier, but was still missing in Android. This has now been aligned and corrected.

Various bug fixes and improvements.

What's been fixed and improved:

Camera / Scanner Issue Fixed

The known camera issue has been resolved. The cause was, among other things, an overlay above the scanner that prevented matches from being recognized properly. This overlay has been removed, making the scanner feel faster and more reliable.

🧭 Wrong View & Missing Options Fixed

After fixing the camera, sometimes the wrong view was shown — this has now been corrected. The 'Sold' option was missing in some situations and has now been properly added back.

🔁 Aligned with iOS

All new features and improvements that are in the iOS update have now also been added to Android.

🎨 Focus for Future Updates

I'm now going to focus more on the design of the Android app. On iOS I use Liquid Glass, Apple's new design language, which I'm very happy with. Android still feels a bit more outdated to me, and I'm going to look into how I can make this more modern. My priority is first a stable and well-functioning app — design comes after.

Thanks for all the feedback and patience! As always: please keep sharing bugs or ideas.
