App support

How can I help?

This page provides support for all iPhone, iPad, and Mac apps published by Luke McLaughlin. For the fastest help, include the app name and your device details when you get in touch.

Quick troubleshooting

  1. Update the app and your operating system to the latest available versions.
  2. Quit and reopen the app, then restart your device if the issue continues.
  3. For purchase issues, use the app's Restore Purchases button.
  4. Note what you were doing immediately before the problem appeared.

Subscriptions and purchases

App Store payments and subscription billing are managed by Apple. You can view, change, or cancel a subscription in your Apple Account settings.

For refunds or billing assistance, visit Apple's Report a Problem.

Privacy and terms

Read the privacy policy for information about how app data is handled.

Unless an app states otherwise, use is governed by Apple's Standard End User License Agreement.

Accessibility

If an app is difficult to use with VoiceOver, larger text, keyboard control, reduced motion, or another accessibility setting, please report the app name, device, and feature involved.

Blitzer file-transfer help

Install and open Blitzer on both devices, allow Local Network access, choose the nearby device, and confirm that the same six-digit pairing code appears on both screens. The receiver must approve every incoming transfer. On iPhone and iPad, keep Blitzer open while a transfer is running.

For a direct Mac-to-Mac route, connect a genuine Thunderbolt cable and configure Thunderbolt Bridge in macOS Network settings. For local Wi-Fi or Ethernet, enable those routes in Blitzer Settings on the Mac. Blitzer never uses cellular data or a developer-operated cloud relay for file payloads.

The Free plan can send up to 5 GB in each transfer and can receive without a plan-based size limit. Blitzer Pro Lifetime is a one-time App Store purchase that removes the plan-based outgoing limit. Use Restore Purchases in Blitzer Settings if an expected purchase does not appear.

If discovery or pairing fails, keep both devices awake, confirm they are on the same trusted local network, verify Local Network permission, and restart Blitzer. Never approve pairing when the displayed codes differ.

Contact app support
