Look forward to seeing your 225 bench on the feed ;) ### 5/5 — Amazing app! *2025-01-12, version 1.1.21* The Arnii fitness app has been user friendly and fun. This app provides community support, allowing users to connect with friends and other fitness enthusiasts throughout the city and around the globe, encouraging users to stay consistent with their goals. Users are also able to engage in fitness competitions based on their fitness rankings. The Arnii Fitness app also provides other features which makes tracking your fitness progress fun and effective! ### 5/5 — Wow!!! *2025-01-10, version 1.1.21* This app is awesome, not only is it easy to use but very useful as well!!! Tracking my workouts is a game changer and competing with not only my friends but other gyms, around the world?!?! Absolutely a must get app!!! ### 5/5 — Accountability *2025-01-10, version 1.1.21* Love the app for its natural ability to push for accountability with your own workouts. It’s also a fun way to connect with the community within your gym and gyms across the local Communities, local cities and across the globe. I love how you can track your progress and see your high and low days and analyze what can be changed in your workouts to improve. For example: on a high stress and low nutritional value day, you may not be able to lift as heavy or feel as accomplished with your workout. However, you can look back and see what fuels your workouts the best. Having friends on the app is a great motivation to keep aiming for improvement. It has definitely brought out a sense of pride in my gym community. It has also definitely brought out my competitive streak!!! Holy 😱👀 ### 5/5 — Awesome app to build community! *2025-01-10, version 1.1.21* The app is easy to use and clever. Been using it at our gym to facilitate more engagement amongst our members and so far it has been a lot of fun! People log their workouts in and are pushed by others also using the app. We see it as a great thing as it promotes use of our facility and members getting stronger and pushing more towards their fitness goals. All good competitive fun! ### 5/5 — Excellent workout app *2024-12-22, version 1.1.18* Very motivating app! Makes me want to log in everyday and do better. ### 5/5 — Great App for Tracking Workout! *2024-11-28, version 1.1.12* Love the competition aspect. Very easy UI to understand. ### 5/5 — Simple and fun *2024-11-25, version 1.1.12* First workout tracking app I’ve ever downloaded and it’s pretty great. I use it to track my own workouts and as a way to improve. Prior to the app, I fell into a loop of doing the same workout and the same weight but using this app motivates me to be stronger because I want to see the numbers get higher. Good signals/symbols in the app to show progression and since it is a social app, you know you’re not alone. ### 5/5 — Best gym app! *2024-11-23, version 1.1.12* Love using Arnii to track my workouts and see what my friends are up to! Keeps me motivated to workout and it’s a great app to keep track of my own progress! Also love that you can track cardio workouts, weight training, and Pilates!! Super well rounded app <3 ### 5/5 — UK is 2nd strongest country now! *2024-11-23, version 1.1.12* Love the app, been working out forever and it’s great to see which country is the strongest based on gym tracking! Super simple, motivating and fun! ### 5/5 — Great way to track and benchmark *2024-11-23* Arnii is an easy to use great way to track my traditional weight training exercises and has a really cool benchmarking feature that allows me to see what others (with similar goals) are doing. I can’t wait to see how this improves over time. **Developer response:** Thanks for the detailed comment! We are making Arnii better and better every day, with the goal of creating a connected gym community--happy to have you part of the movement! ### 5/5 — Best workout app *2024-11-22* I’ve been using Arnii for a couple months now, and it’s hands down the best fitness app for the gym, running, everything really! You can track almost all your workouts. It’s versatile and I love how you can see your progress overtime to see if you’re actually improving. Everyone needs this app!! 🙌. You can also follow your friends and share/see each others workouts! **Developer response:** Thanks for the kind comment, and happy to have you part of the Arnii Community! ### 5/5 — Amazing app. Highly recommend *2024-10-30, version 1.1.8* This is the amazing app for fitness tracking. You can see you progress day by day. Easy to use; all functions run smoothly. The best fitness app ever. Give it a try, and you will love it! ## Most critical reviews (10 lowest-rated) ### 1/5 — Clunky, Bloated, Can’t Delete Account and private information *2026-02-02* The app is forcing you on the map in the Vancouver Canada location, probably to make it look like a lot of people are using the app, that there’s a high concentration of people in the area. It’s super clunky and slow to respond to movements of the map. You also can’t delete your account if you don’t want to use the app anymore. The in app behavior seems geared to force you to stay. It also collects your private health information and there’s no way for you to have them removed once you’ve given it to them. **Developer response:** hey! adam here, the solo dev. thanks for this feedback, it genuinely pushed me to make real improvements. i want to address everything directly: ✅ the vancouver default has been updated; the app no longer suggests that location on startup. ✅ performance has been significantly improved; map responsiveness and movement should feel much snappier now. ✅ account deletion is available in settings, and i've made it more visible so it's easier to find. ✅ health data: your data is only used to power the game mechanics, never sold or shared; and deleting your account removes all your data entirely. if you have any more feedback, dm me on instagram @chewylift or email info@arniifitness.io... i respond to everything myself. thanks for helping make checkin better 🙏 ### 1/5 — Clunky, Bloated, Can’t Delete Acount *2026-01-31* The app is forcing you on the map in the Vancouver Canada location, probably to make it look like a lot of people are using the app, that there’s a high concentration of people in the area.

If you're still interested in free lifetime. dm @chewylift on instagram with your old account details! ### 1/5 — Horrid *2025-01-10* One thing after the other could not register for this. ONE STAR!!! **Developer response:** Hi there! The onboarding is similar to all other fitness & gym apps, and all information is kept private and only used to personalize Arnii. Let me know how i can help, as we were having free giveaways during your sign up! contact: info@arniifitness.io ### 1/5 — Don’t waste your time! Cannot register *2024-11-23* Impossible to register into the app! Be careful. Dont waste your time **Developer response:** Hey! Sorry to hear you had issues with registering. Please email info@arniifitness.io, as I would love to help you get started to be part of the community! - App Founder, Adam ### 2/5 — Glitch *2025-11-21, version 2.0.9* I love using this app to track my workouts but since teams were added it wont let me choose one. And just stays stuck on that screen ### 2/5 — Can’t continue with the location/city *2025-05-30* It asks me to add city or gym, but even if I do it doesn’t continue. Now I can’t get the lifetime due to that! **Developer response:** Hey! Sorry you ran into the issue. I'm happy to provide you our promotion still. Please email us a screenshot of the location you selected with the error to info@arniifitness.io ! ### 5/5 — THE Future of fitness motivation *2026-01-29, version 2.1.5* This app is going to be huge. It adds a fun competitive edge to staying fit. Watch me take over the world! ### 5/5 — Competitive with my friends *2025-12-30, version 2.1.1* Need to beat my friends with territory ### 5/5 — It’s addicting *2025-12-15, version 2.1.0* Love this app!! ## Most praised reviews (7 highest-rated) ### 5/5 — Fun map game! *2025-12-11, version 2.1.0* Gets me motivated to run and compete with friends ### 5/5 — Fantastic for tracking workouts *2025-11-21, version 2.0.9* Especially love the new gym war feature, super neat! ### 5/5 — Sick af *2025-11-13, version 2.0.8* Starting beef with my bois.

I use it to track my progress on lifts, build workout plans and see how everyone else in my city and around the world is lifting. It makes me want to go to the gym (when I’m not busy) due to the competitive aspect of the app (wanting to be the strongest lifter in my city). The AI feature for building workout splits is also great when I want to switch it up. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
