Contacted sales and support requesting a refund. No response. Save your money and time as this is very frustrating. If I had the money to purchase another program I’d dump Synthesis even though I’ve used it for 13 years. I don’t tolerate no responses.

This app needs improvement. I paid $100 for the premium version and it’s been FOUR times that the app glitches and loses its features. As per their support team, it’s unclear what causes this, and I’m not the only one. The only solution they have is delete the app, reinstall, and lose all your saved clipboard data… It’s a total waste of money and time! If we’re going to be asked to do this over and over again, then you should offer iCloud backup to restore data or a refund for the inconvenience.

The app is okay, nothing extraordinary. The thing is that they don’t have competition so they settle for mediocre. You can install it in two devices, which files never synchronized, therefore I had to enter the data manually on each one so they had the same data. I tried to install the Premium features which cost additional Ca$40 and they never worked. I found an online thread that suggested you delete the app and re-install it and so I did and lost all my files (a nightmare!) and still didn’t have the “Premium Features”. Therefore I asked Apple for a refund which was granted. Then I contacted the company asking for support to install the Premium features before I tried purchased them again from the app store and never contacted me a week later. At Cad$180 plus tax, the app is quite expensive already and you’d expect more reactivity and a better customer service from the company. When I got a response from a Customer Representative, who had no idea what I was talking about and didn’t know how the app works at all. On one side you could notice that he didn’t know how to use it, what I even talking about, even less to troubleshoot for this app and that he didn’t even understand English and was using probably Google translation to communicate. The experience was so terrible and frustrating that I decided just to give up. I won’t be buying the Premium features. Also, from what I understood, you have to buy the Premium for each one of your devices, you cannot use the same subscription on two devices like the core subscription. If they have such a terrible service for the app I can’t even imagine the frustration if you pay thousands of dollars for the RadarOpus software and do the same! If you purchase this app be aware of the non-existent customer support and all the glitches and inconveniences it has.

This app needs improvement. I paid $100 for the premium version and it’s twice now that I’ve been forced to delete the app and reinstall because the premium features go missing. It’s a total waste because all my data is lost and there is no way to recover it. If we’re going to be asked to do this over and over again, then you should offer iCloud backup to restore data or a refund for the inconvenience. The Zeus Support also needs to be re-trained in what customer service means because there was no sense of customer and no sense of service when I’ve contacted them

This app is wonderful, very easy to use and faster to search than the book (Synthesis 9.1). As a student of homeopathy I find it is great way to learn to navigate the repertory. I also like the initial analysis it provides on selected ruberics. Plus, it is portable, unlike most repertories, and can come along with me on my travels. I look forward to trying the import into RadarOpus feature to continue case analysis.

I’ve spent $130 on the app and another $30 on the premium features. The app is okay but now it’s asking me to buy the premium features again… I’ve contacted tech support by email yesterday and by ticket today. I’m still waiting to hear back and I cannot use the features until they respond. I’m obviously mot paying another $30 for what seems to be a problem on their end. Even after following the steps on their online forum, which includes restarting app, and deleting and re-installing, the issue is still there. I can see in the forum that more than 1,113 people have viewed the same post, presumably most of them having issues with the in-app purchases… Please fix this or provide proper tech support 🙏🏼
