Frequently asked questions

Data saved in each app is stored only in that app's dedicated folder on your own device. It is never uploaded to or kept on my servers.

This also means that deleting an app deletes the data saved in it. I strongly recommend backing up anything important to a computer on a regular basis.

Swipe the item to the left in the list to reveal the delete button, then tap it.

Deleting from inside the app removes the data immediately and permanently — there is no trash to recover it from, so please double-check before you delete.

Low storage space on your device can cause a range of problems, including save errors and rendering failures. Check your free space under Settings → General → iPhone Storage, remove what you no longer need, and try again.

If only certain sites misbehave in an app with a built-in browser, try "Clear All Cache" in the Settings tab, then fully quit and relaunch the app.

The benefits differ per app, but every app removes ads with Premium.

In concat-img, Premium additionally unlocks exporting selected images as a PDF. In the remaining apps, removing ads is the only Premium benefit.

For iDig and iCap, see the iDig FAQ and each app's own page.

Open the Settings tab, go to "Buy" → "About Premium", and tap "Restore purchases". If that does not work, tap "Verify receipt" on the same screen. You may be asked for your Apple ID password when you run it.

In both cases you must be signed in with the same Apple ID you used for the purchase. If neither step restores your purchase, please contact me through the contact form.

The app has three tabs: "Join images", "Clips" and "Settings". Pick the images you want to combine on the Join images tab; the result is saved to the Clips tab.

Exporting selected images as a PDF is a Premium-only feature.

The app has four tabs: "Browser", "Tabs", "Clips" and "Settings". Open the page you want on the Browser tab and run the capture; a preview appears first, and tapping save stores it in the Clips tab.

Full-page captures can be exported as either a PDF or an image. For very long pages, the image export may be split across several files.

The app has three tabs: "Browser", "Clips" and "Settings". Search using an image you already have, and review the results from the Clips tab.

The app has three tabs: "Folder", "Import" and "Settings". Import videos from your device on the Import tab and they will appear in the list on the Folder tab.

To keep playback going while you use another app, check the Picture in Picture settings in the Settings tab.

The app has three tabs: "Folder", "Browser" and "Settings". Your notes are listed on the Folder tab; open one to edit it. Bulk replace is available from the note editing screen.

The apps support 16 languages: Japanese, English, Simplified Chinese, Traditional Chinese, Korean, Indonesian, Vietnamese, Thai, Spanish, Portuguese (Brazil), French, German, Polish, Swedish, Turkish and Ukrainian. The display language follows your device's language setting automatically.

You can reach me from the Settings tab under "About this app" → "Email a bug or request". The contact form on this site works too — attaching a screenshot makes it much easier for me to understand what is happening.
