The Stone MD app is for people with kidney stones who may benefit from changes to their diet. To use the app, you should know details about your stone, such as its type, makeup, and location, as well as other health information. The app then estimates your risk of having another kidney stone in 2, 5, and 10 years and provides dietary recommendations to help you reduce this risk.

You can get tips on how to lower your chances of getting more kidney stones through guidance on daily water intake and diet.
You can set reminders to drink water and log what you eat by choosing from a food list. The app then calculates your daily intake of calcium, protein, and calories. This information can be turned into graphs to help you track progress over time. You can also use a diary feature to track urinary pH levels.
The app also provides educational content on the surgical management of kidney stones with YouTube videos to help you better understand the procedures.
If you have a ureteral stent, the app offers a place to record details like the stent’s location, insertion date, planned removal date, doctor contact info, and any additional notes.

Clinical review

Reviewer: Johanna Lim, Clinical Pharmacist (Cardiology Expert), Health NZ Te Whatu Ora Te Matau a Māui Hawke’s Bay
Date of review: July 2025
Platform: Apple
Version: 2.4
Comments: Overall, Stone MD is a useful app that provides your risk of recurrent kidney stones across a 10-year period, with added recommendations on water and food intake to help reduce the risk. The risk is based off the clinically validated ROKS nomogram. Use of the app may be challenging however as it contains medical jargon throughout, and relies on you knowing the type, location and composition of your kidney stone. The educational content on surgical options is useful. Some parts of the app are limited to Russian language only, which may restrict some users from the full benefit of using the app.
Safety concerns: Relatively safe app when used in conjunction with medical advice from your healthcare professional.
The information in this app should not replace medical advice.
The app relies on you knowing details about your kidney stones to calculate the risk of recurrence. The results may not be reliable if you don't know the type, location, and composition of your kidney stone.
New Zealand relevance: Yes (mostly).
Concerns: Input of food can be challenging as this section is in Russian language.
