Someone is getting lazy because this app is very bad in linking information and updating the content. I tried to enter 3 coins. Ended up having multiple coins repeating in the same album and I couldn’t get rid of the duplication. I ended up deleting the coin then deleting the album. Still saw the coins in the coin tab but all the info was gone or mixed up. FRUSTRATING I have better thing to do with my day off. And btw what is ruler and bib.ref. There should be more user help if I have to input all the information myself. I didn’t mind the work but when it stopped working I gave up. ### 4/5 — Great free app! *2018-02-16* Free is great! I have found this fun and useful to help keep my collection organized. I have found it still has a few bugs though, I’ve got several hundred pics loaded and the load times are getting slow and the coin info often doesn’t load when clicked on. When I tap on the share icon it does load so at least I’ve found a work around. All in all it has great potential and so far I’m enjoying the Free app! **Developer response:** Hello! Thank you for your feedback. I am constantly working on the app to improve it. If you have specific issues I will be glad to fix them. Please let me know, Your feedback is welcome! ### 1/5 — UPDATE WILL DELETE YOUR FILES! *2017-10-19* LOST ALL DATA ON 158 COINS WHEN UPDATED TO LATEST VERSION. COUNTLESS HOURS OF RESEARCH & CATALOGING LOST. INCREDIBLY IRRESPONSIBLE APP MANAGEMENT. THIS THIBG HAD SUCH POTENTIAL - WILL NOT TRUST MY COLLECTION HERE EVER AGAIN. **Developer response:** Hello, I am very sorry to hear this. If you synced your collection, your data may be recovered. You can ask for support privately, I will be glad to help. I am constantly working on the app to improve it, and I encourage you to upgrade to the latest version and give it a second chance. Now there is also a desktop version available for both macs and PCs. ### 1/5 — Hour of Work Gone *2017-09-29* I liked Syllogy until I uploaded the latest update. Boom all my files disappeared - 7 albums with over 75 coin, all researched and photographed. **Developer response:** Hello, I am very sorry to hear this. If you need support, please contact my be email. I am sorry that I read your review only now. If you synced your collection, your data should be recoverable. If you want we can give it a try.
