I would rate this considerably higher if the cost of upgrading to "Pro" were a bit more reasonable. For free, you can use 3 different designs I believe, which may be sufficient for most people. I'm as happy as the next guy to support a good app but then I saw that "Pro" is on a subscription model. It's currently $.99 a month, $6.99 a year, or $19.99 for lifetime. The yearly price would be the absolute maximum I would want to pay for lifetime access, and even that is a little high.

Thank you for your honest feedback 🙏 We truly appreciate your support. We understand your concerns about pricing—developing and maintaining the app has real costs, and to keep a clean experience, we don’t include ads for free or Pro users. We’ll also keep adding more useful features for Pro and consider your pricing feedback ❤️

This app is awesome! It's super easy to use and has this cool frame I was looking for. There's a free version with a Xiaomi-style frame and three options, but the rest is paid with a subscription. The best part for me is that it's totally ad-free. You can customize a lot, like changing the detected brand or ISO. Overall, it's a great app, and I totally recommend it if you want that free Xiaomi-style frame.

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!
