If you sell something to someone permanently you can’t just take access away because you want more money. Since I posted this I used Ai to build a free replacement of your app in less than 5 minutes so I won’t need your “free” 3 months that you offered. I purchased this app only for them to take it away for me because “ given the current economic environment, we had to change our business model.” I don’t understand how I can purchase something permanently and you just remove my access because you need to make more money. ### 1/5 — Used to be free *2026-02-23, version 2.56* Used to be a free app on the last platform I used now they want you to sign up for premium after 2 weeks and lock the rest. ### 1/5 — Always opens to community highlight *2023-12-12, version 2.50* The app never opens directly to the workout but instead always opens to a community highlight. Also, there is no opting to change the workout intensity based on fitness level. ### 5/5 — So good *2023-02-23, version 2.48* Best app ever ### 3/5 — Only the beginning is free *2021-06-14, version 2.2.11* This is a good app, but you only get the first few days free. Once you get to a certain level you need to pay to unlock the rest. ### 1/5 — ACCESS BLOCKED AFTER APP PURCHASED *2021-01-29, version 2.2.10* I purchased a few apps from Zen Labs Fitness in 2019 with the understanding that it was a one time purchase. Now I’m locked out of my apps because of a forced subscription. Multiple emails to customer service to fix the issue have been ignored. Beware. ### 4/5 — Locked out - fixed *2021-01-26, version 2.2.10* I purchased the sit-ups, push-ups, pull-ups, and squats package and now I’m locked out and they won’t answer my email. Zen labs contacted us and unlocked the account. ### 1/5 — This company does bait and switch. *2021-01-22, version 2.2.10* Two years ago I paid $29.99 for their unlimited running and weight training app. Since then (last month) they “changed their model” and have a subscription service. Never mind my contract. Never mind their word. If I want to access portions of some of the apps I PAID for in full I have to pay $10 a month. Not worth it. These are simple apps no one should pay $10/ month for. Add to that that they lie and go back on their word, why work with them at all. And when I email support they send me to Apple for a refund. Apple will not refund a two year old purchase no matter what their contract says. This company is irresponsible and they are liars. Stay away. Stay far away. Give them none of your money. ### 1/5 — Scammers! *2021-01-22, version 2.2.10* I paid for this and other apps in one of their bundles. Now they’ve pulled the rug out from under me and made this a stupid subscription-based app with freaking ads! This is unconscionable! ### 1/5 — It was a really good app... *2021-01-07, version 2.2.8* Until it wants more money. I paid for the app, and then at the last update, it now requires a monthly subscription. Why would I pay twice? ## Frequently asked questions about 0 ### What does the 0-200 Situps Trainer Challenge app do?
