Swiftgram Pro is a paid subscription in iOS app @Swiftgram. Subscribing, you get access to Pro features, such as Accounts Backup, Message Filter, Formatting Panel and more.
Swiftgram Pro does not aim to replace Telegram Premium and works as a perfect addition to Telegram's subscription.

Swiftgram provides 60+ features and improvements over Telegram app. Innovating and keeping Swiftgram in sync with monthly Telegram updates is a huge effort that requires a lot of time and expensive hardware.

I want to cover expenses and monetize my efforts. Subscribing to Swiftgram Pro you get cool features and support an independent developer.

Of course. Existing free features remain free.

Yes. While I will be focusing on and fine-tuning Pro, trying to attract more users into it, Swiftgram will still offer new non-paid features.

I have recurrent costs to run Swiftgram, such as Apple Developer account, infrastructure, powerful Mac to build Swiftgram fast, etc. I spend time adopting monthly Telegram source code updates and ensure Swiftgram features will work without conflicts.

There're no reasons for me to charge one-time payment for many-times expenses and effort. Even with a big one-time payment, at some point, it will stop "breaking even" and I will be losing money due to "lifetime" commitment.

Beta payments are not real, so I'm not receiving any money from them. Install App Store version on top of your Beta to make a purchase. You shouldn't lose any data, but your accounts is your responsibility.
Beta slot will be reserved for you, so you can return back to Beta after successful subscription.

No for now. Keep in mind that Apple, Banks and Governments apply huge Fees and Taxes, so only a smaller portion of a payment reaches my pocket (less than 50%). I'm investigating other payment methods that can make a deal even better for both me and you.

Yes, Swiftgram app is entirely open-source, even Pro features. source.swiftgram.app
I believe that openness and transparency is an incredible value of Swiftgram, so people will be happy to support author they trust.

I don't like what others do, this is why I’ve created Swiftgram. Swiftgram is here to stay for a long time. Reasonably monetizing the app I make sure it can be independent from third-parties and not rely on sketchy ads or hype features that boost valuation, instead of giving value to users. Perhaps, adding a little to price.
I use my own app daily, so Subscription is not only about Pro features, it's about principles and vision of a nice best iOS Fork. I've started this journey 6 years ago and there more to come.

Feel free to drop your message to @swiftgramchat, I will see it!
