No pricing on calculation *2025-05-20, version 4.9.291* Randomly stopped working. ### 1/5 — Calculator stopped working *2025-05-15* As others have stated, the calculator does not provide estimates any longer after the most recent update.

The diamond rates are not showing up as they used to, and we are now forced to calculate everything manually. This has made the process very inconvenient and time-consuming. Please fix this issue as soon as possible so that the app can function as it did before. ### 1/5 — Problem in rap update *2025-05-09* Suddenly the app has stopped showing rap price in iOS neither its showing any option on how to update price please look into the matter and solve the problem asap ### 1/5 — App not working after recent update *2025-05-05* App is not working after recent update and no support to help can you review to fix the issue ASAP please ### 1/5 — Degraded the App *2025-05-01* Now the app requires you to manually enter the rap price which defeats the purpose of paying for this app. Earlier, the rap price used to show automatically for each configuration. ### 1/5 — App not working *2025-04-30* Your app is not working for last month i tried calling on your help line number but no response ### 1/5 — No longer working *2025-04-30* After an update it no longer works with no help from support. Look elsewhere folks. ### 1/5 — Stopped working *2025-04-29* Doesn’t give prices anymore ### 1/5 — Rap price are stop after last update *2025-04-26* I am totally agree with many other reviewers recently the App don’t worth if it did not provide rap price, it is now useless please don’t get it until they put rap list back. It’s worth less now after new update. ## Most critical reviews (10 lowest-rated) ### 1/5 — - *2026-06-10* Paid ₹699 for the app, but unable to use it due to OTP issues. The app shows "OTP sent successfully" but no OTP is received via SMS or WhatsApp. Tried multiple times without success. Support response is also pending. Buyers should confirm login and OTP functionality before purchasing. Very disappointing experience. ### 1/5 — Don’t Pay *2026-01-11* This app has stop working since few months back ### 1/5 — Doesn’t work *2025-10-28* 👎 ### 1/5 — Перестало обновлять прайс *2025-07-25* Перестало обновлять и отображать прайс ### 1/5 — Rap not updating in the app *2025-07-18* Rap not updating in the app. Not able to login since OTP quota is exceeded. I'm a paid subscriber and still facing issues. No response from developer despite reaching out. ### 1/5 — Worst Experience – Can’t Even Log In *2025-07-16* I paid for this service, but I can’t even log in. I never received the OTP via SMS or any other method, and now it says I’ve exceeded the quota. How is that possible when I haven’t even gotten access yet? This is extremely frustrating and unprofessional. If you’re going to offer a paid service, make sure the basic login process works. Support is unhelpful, and I’m left locked out despite being a paying user. Total waste of time and money. ### 1/5 — Unable to Log *2025-07-12* I just update the paid version of my app. I am unable to log. As no password/ otp is coming on my registered mobile number. All of a sudden I am unable to fetch rates of diamonds on the app. ### 1/5 — Big problem *2025-06-14* Doesn’t work. ### 1/5 — App is not working *2025-06-12* Price per carat isn’t showing up when parameters are input ### 1/5 — App not logging in and not showing the market price! *2025-06-12* This app was so helpful to calculate diamond prices at ease, off lately it’s become such a useless one! If we have to manually calculate then what’s the point of this app! Please kindly fix this issue at the very earliest! ## Most praised reviews (8 highest-rated) ### 5/5 — App is working good *2026-08-25* "Best app for diamond traders and manufacturers.
