Nice app with good-looking templates, and the Pro version is good. However, many templates do not fit Instagram’s original post size, especially those with infographics at the bottom, which forces you to crop the photo. It would be great to have templates that fit Instagram posts properly without backgrounds. Also, some templates have very limited text input (around eight characters), which is not practical. Overall, a good app, but it needs improvements in sizing and text flexibility.

Thanks for the detailed feedback — we really appreciate it 🙏 Under Aspect Ratio, the editor offers Instagram-optimized 1:1 and 4:5, each with Crop and Original/Fit (no-crop) modes. We’re also working on more flexible text input and adding more aspect ratios in future updates. Thanks again for helping us improve!

I've subscribed to Pro. Please let us adjust the photo inside the frame, as simple as pinching the photo. I want a simple feature that allows us to reframe the photo, such as if I want to post a 4:5 photo inside a 4:5 frame. Currently, you make it automatically crop the top and bottom parts of it, which I dislike.

This is the best 3rd-party app for framing pictures using EXIF data, hands down. I REALLY REALLY wish there was more than one free frame.
