Jack Baty, a resident of the United States, has successfully lost more than 34 pounds following heart surgery, thanks to a digital health tool known as the Simple App. His remarkable journey highlights the potential of technology in supporting sustainable weight loss and improving overall health.
Baty’s health challenges began two decades ago when he was diagnosed with diabetes and obesity. These conditions led to a frustrating cycle of weight gain and fatigue, ultimately culminating in a triple cardiac bypass surgery just over three years ago. While he managed to shed around 70 pounds during cardiac rehabilitation, he faced a plateau and struggled to make further progress.
The turning point in Baty’s journey came when he discovered the Simple App. After completing a brief questionnaire, the app generated a personalized plan designed to fit seamlessly into his daily life. Unlike many traditional diets that focus on calorie counting, the Simple App promotes gradual enhancements to nutrition and lifestyle choices. Baty stated, “I hit the plateau at around 210, and just couldn’t get past it.”
Encouraged by a promotional offer, Baty signed up for a trial period with the app, hoping it would provide the support he needed to achieve his health goals. “I was hopeful that this extra boost could help me continue my march toward a healthier weight, but had doubts,” he reflected.
According to the app’s records, Baty has consistently logged his progress for over 180 consecutive days and has lost 34.4 pounds during this time. His transformation has not gone unnoticed by friends and family. “We went to a friend’s memorial service and people who hadn’t seen me for a while were amazed by my physical transformation,” he said.
The Simple App employs a flexible methodology that allows users to track meals through text, voice, or photographs. It also features an intermittent fasting monitor and customized exercise programs ranging from walking and yoga to high-intensity interval training (HIIT). Avo, the app’s AI-driven coach, answers user queries about nutrition and fitness in clear, accessible language. Recently, Simple introduced Blinky, an emotional support tool designed to help users stay motivated in a more relatable way.
Baty’s experience illustrates that the benefits of the Simple App extend beyond mere weight loss. “I’m sleeping better than ever and even playing ping-pong at the local rec center three days a week,” he noted. His most significant achievement, he added, is no longer being classified as “obese” for his height. Instead, his doctor’s chart now reflects a weight within the upper range of “normal weight” for the first time.
The Simple App has gained significant traction, assisting users in losing over 18 million pounds globally. Recognized as the Best Virtual Health Coach in 2025, the app holds a rating of 4.7 on the App Store with more than 21 million downloads. Currently, it is offering a promotional discount of 60 percent on weight loss plans, along with a two-for-one subscription that allows users to share access with a partner or relative.
Baty expressed his satisfaction with the program, highlighting improvements in energy levels, self-esteem, and flexibility. “More energy, increased self-esteem, better flexibility and a sense of accomplishment all came with the Simple app’s guided eating and exercise tips,” he stated.
In contrast, other platforms like Noom focus on mindful eating, providing personalized courses that adapt to individual needs. Pricing varies based on the plan and user specifications. Similarly, MyFitnessPal offers calorie-tracking services, helping users monitor their nutritional intake, although it comes at a cost of £19.99 monthly, with some features available for free.
User feedback on the Simple App has been largely positive, with many praising its motivational features. One user noted, “Having a regular check-in about what you ate and keeping record of the pounds I am losing is very motivating.” Another commented on the app’s educational value, stating, “It is definitely keeping me focused and accountable.”
Despite some balanced critiques regarding the learning curve, the majority of users report satisfaction. Many appreciate the app’s supportive approach to logging food intake, activity, and hydration, alongside the added benefit of a virtual coach for guidance.
As Baty continues his health journey, he looks forward to maintaining his progress and further improving his quality of life. His story serves as a testament to the potential of innovative technology in fostering lasting change in health and wellness.
