"We were on a tight schedule for the release of the new app, and Glassfy’s help with the integration was instrumental to us hitting the deadline. It would have been a lot more difficult without their help! Glassfy solves a big problem for app publishers, and it's very well developed; well done!"

"I've been using Glassfy for a while now and it is a very useful tool, as I can easily manage my in-app subscriptions with a little coding but also I can access a lot of statistics and useful data to improve the retention and reduce the churn. Furthermore, the Glassfy team is super responsive and very professional. I love working with them."

Labyrinthos

"As a designer that doesn't professionally code, the idea of integrating in-app-purchases was incredibly intimidating. It was so intimidating that I had put off monetizing my app for a long time. I discovered Glassfy after coming across a tutorial, and it was shockingly easy to get everything connected. Plus support has been responsive and kind!"

UniTaskr

Travis, CTO

"We've implemented Glassfy for in-app subscriptions at UniTaskr! Across the team we've implemented so many different payment mechanisms and Glassfy was a super pleasant surprise! We had budgeted days to get IAPs working correctly and had it done by lunch time. Too easy. Reporting and insights have been straight forward too. Customer support is top notch."

"Glassfy - allowed us to add multiple stores (Paddle) to our business. It enables a true cross channel distribution (web+mobile) supporting our hybrid sales strategy (B2C+B2B). They are the right partner to help us grow our revenues in a smart and ambitious way without the implementation and maintenance burden"

Law of Attraction

Dave, Founder and CEO

"After researching different ways to implement subscriptions into my app I stumbled across Glassfy and I am really pleased I did. I was able to implement subscriptions easily with just a few lines of code. The demo and support I received through the process were swift and helpful, and I now have subscriptions and receipt validation working in my app with just a handful of swift functions. I highly recommend this SDK to anyone who wants a quick and easy way to add subscriptions to their app!"

Fudget

Danny Connell, Creator

“Glassfy has made it incredibly simple to unify Fudget’s subscriptions across iOS, Android, Mac & Windows. A user can subscribe on iOS, then download the Mac version & access their subscription. This would’ve been close to impossible to set up without Glassfy. When I had issues setting up Glassfy, the team were quick to respond & super helpful. I love Glassfy!”
