  1. 5/5Used it for years, a few suggestions for new UI

    I have used this app for many years now and it’s an easy 5/5. Set up your training max and it auto-calculates weights based on percentages. It’s relatively easy to edit templates and add accessories as well. Starting a new week automatically increases your weights, it all could not be easier! A few pieces of constructive feedback on the new UI: 1) please, please, please allow us to use the app fully during the rest timer. With the new UI you can either have a rest timer or skip it to use the app to check your next set’s weight or upcoming accessories for a superset. I use rest to review and set up my next sets or exercise, and would prefer not to have to choose between a rest timer or time saved in the gym. the previous UI’s rest timer was nicely positioned at the bottom of the screen but still allowed us to navigate the rest of the app! 2) create a ‘condensed mode’ to show more information on the screen. NSuns has a lot of sets! And it now requires a lot of scrolling to see them all (and you cannot scroll down during a rest timer). similarly, the old UI was more compact and we could see a lot more without needing to scroll 3) allow us to tap on an accessory as we could previously to open up the weight/sets. The new ‘manage’ feature is nice but if I have 4-6 accessory exercises, I need to consistently scroll down the ‘manage’ window to check off sets 4) a nice to have, not related to the new UI is the ability to create supersets for accessories!

  2. 5/5Honestly cannot believe this is free.

    Firstly, this is hands down better than most if not all premium workout apps out there. All you do is input some initial numbers when you first open the app, and then it keeps track and also progresses all your lifts for you weekly. I’m currently doing the 6-Day Deadlift program, and I’ve been using it every day for the past 5 weeks. If 6 days per week is too much for you, there are also 4 and 5 day options as well. This is the first time in years I’ve been motivated enough to gym consistently, and this app has been essential through it all. Huge thanks to this amazing app developer. I encourage everyone to donate through the app, because it is genuinely well deserved and worth the money. One suggestion: If the app could somehow track the progression of other things, like accessories, body weight, etc, that would be unbelievable. Thanks again, and looking forward to your future updates and improvements!

  3. 5/5No other program like it

    I’m a (former) veteran hardgainer, but I’ve been working out seriously since I was a Junior in high school (about two years). I’ve tried a few other programs for 4-5 months at a time, always with gains in mass and strength but not quite as fast as most of my peers. However that all changed as soon as I started nSuns, specifically with this app. I put on 30lbs in three and 1/2 months, mostly in muscle, and joined the 1000lb club, and I’d credit most of that progress to this app. The developer did a great job with it in every way. There are virtually no glitches and the quality of the layout is better than some premium apps I’ve tried for other programs. Specifically I used the 6-day squat variant but changed around the order of the days to emphasize squat more. The program itself is weird af, but it works. I’m kicking myself that I didn’t start using this app two years ago.

  4. 5/5Fantastic Program

    This is easily the best workout program I've done. I've gotten the most gains I've ever had and I've had the most fun I've had doing it. I'm so glad I found this app because it's honestly improved my life by making me enjoy lifting for the first time in my life. And it's free to boot! However, I will be donating if possible (need to look). There are only a few improvements I think would make it even that much better. It would be great if I could input a max weight for an accessory workout and have it set my sets and weights just like the second exercise. I also have issues with the countdown timer. If I leave the app and come back, the timer disappears when I come back in. There is also no alarm/beep sound for me when the timer hits zero.

  5. 5/5Great App !

    This app is great it keeps track of all my lifts and seeing my progression over time is sweet. I can really see how much I have grown over time. There are great templates to follow but you can also edit these templates to your liking. I would strongly recommend this app as it is easy to use and FREEE! What would make this app better is if there could be a way to export all the data to an excel sheet or something. Or a way to transfer all the data to a new phone. If someone gets a new phone all their progress and data cannot be transferred and will have to start over from the beginning
