It’s basically all under one roof app. ## Most critical reviews (10 lowest-rated) ### 1/5 — Where’s my paid product? *2020-07-18, version 7.2.8* So I paid a lot of money for this a while ago (including recommending colleagues to purchase this as well), and I updated the app and now the content is gone forcing me to an annual subscription! I paid for a product, so why can’t I have it? ### 1/5 — Absolutely Terrible! *2020-06-11, version 7.2.2* What a complete waste of money! Even after paying it still says i’m in a Demo account however it has an expiration date for my subscription? I just go around in circles with this garbage app. I tried to contact customer services but I got an email back which said ‘Undelivered Mail Returned to Sender’ What a joke!!! I give up! ### 1/5 — No response for developer *2020-05-15, version 7.2* Emailed developer and haven’t heard back. 737NG section will not update neither will the max as well. ### 1/5 — Another subscription *2019-08-31, version 6.1.2* Another app goes the way of subscription. This app and book managed well for years without but now deems it necessary to charge a user fee to “provide optimal” service. There’s better products out there for a one time fee, that provide free updates. Don’t waste your money here. Despite what the producer says, this a clear gouge. Don’t fall for it. ### 1/5 — Rip Off *2019-02-16, version 6.1.2* Unless you read the fine print this just bills your Apple account at the end of the year. What a scam, why not be honest and let people renew on their own? I guess if you can do this once to enough people it is very lucrative. ### 1/5 — Pricing model changed, no option to continue without paying *2018-10-06, version 6.1.2* Not happy that the pricing model has changed. I bought a perpetual licence, but now I’m being told I need to subscribe annually. Fair enough if you want to move to a subscription model, but at least let people keep their old version/content. The 3 year thing is a load of crap. ### 1/5 — cpt *2018-03-09, version 6.1.1* DO NOT BUY, YOU NEED TO PAY EVERY YEAR ### 1/5 — Thank you for forcing me onto a subscription. *2018-01-09, version 6.1.1* After paying outright for the App. Way to treat your customers. ### 1/5 — Money pit *2017-11-26, version 6.0.8* I second below. Me thinks I’m funding this guys retirement plan! Bought the colour printed version for over $100 then the APP for half that and now this...At the end of the day, the content was not really worth it. “I bought the paper copy for over $100 CAD. Then I purchased the APP for my iPad. Now, you expect me to buy into a subscription service? I'm sorry, this is a rip off.” ### 1/5 — Waste of money *2017-01-30, version 6.0* Having paid a high one off fee for this app the developer has decided to change it to a monthly subscription. After 3 months I will not be able to use the app and the money I have spent is wasted. How is this fair?!? Beware of this developer and program! ## Most praised reviews (10 highest-rated) ### 5/5 — B737MRG *2026-08-27* INFORMATIVE INTERACTIVE INTERESTING! **Developer response:** Hi Pilot, thanks for using the app and took the time out to leave us a 5-Star review. -Pat ### 5/5 — Captain *2026-08-24* Best app, you make my life easier ### 5/5 — Best 737 resource *2026-08-02* Too good, thank you Capt ### 5/5 — New update *2026-08-01, version 9.3.2* Hi Pat, New update works a treat!

Thank you for this. ### 5/5 — App *2026-06-10, version 9.3.1* Great job! ### 5/5 — A true companion for 737 *2026-06-07* Using MRG For almost 16 years , A very useful companion in the cockpit during non normal situations. ### 5/5 — Very good *2026-05-27* Very good app specially when you encounter non normal --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
