Developer Response
Thank you for sharing this. Your subscription will appear in next update 3.9. Please wait a couple of days for approval by AppStore. Hot fix is on the way. I'm very sorry for this!
• Easier to get started: clearer Continue buttons and simple goal selection replace the press-and-hold step, with smoother transitions to choosing your first video.
• Simpler AI model selection: cleaner cards highlight speed, quality and Premium availability, with one clear selection indicator. The main Upscale and Convert button shows your chosen quality and model.
• Easier saving and sharing: Save to Photos and Share Video stay visible while you browse comparisons and full video details. Saving includes progress feedback, clear confirmation, protection against duplicate taps and a retry option. If Photos access is blocked, you can open Settings directly.
• More reliable one-off export purchases: improved credit tracking prevents the same purchase from being counted twice and preserves unused export credits when updating.
• Accessibility improvements: clearer labels and selection states for AI models and goal choices, improved text scaling in model cards and the main action button, and a VoiceOver announcement after saving. We have also reduced decorative animations during the introduction and on subscription screens, and added translations for new controls and messages.
