Reviews

What people say.

“This app is great. The user interface is smooth and intuitive. Lots of knobs to turn to explore different retirement scenarios. Also it has a cohesive set of resources organized in a seamless way.”

App Store Review

Salute to Suit on iOS

“This app’s user interface & various calculators are essential tools in planning for retirement, separation, etc. Military math can be complicated but this app makes it easy to see how retirement can forecast over the years using various Monte Carlo simulations.”

App Store Review

Salute to Suit on iOS

“The amount of work that went into this is truly mind blowing!!! Ditching a couple of apps as this covers at least 2 other apps. Thank you!!”

Client Testimonial

“Roman is a passionate app developer, and it's clear that he takes the time to fully understand the technical problem before jumping into a solution. His technical expertise speaks for itself, but what impressed me most was his ability to challenge my thinking, identify blind spots I hadn't considered, and help reinforce and evolve my original idea into something even stronger. I also appreciate the unique perspective he brings from his Air Force and Space Force acquisitions background. He combines that experience with his technical expertise in a way that makes him a true professional and someone I can trust with my future app development needs. I'm excited to continue working with Roman and look forward to having him help me turn my vision into a reality.”
