However, iOS drives have now been supported for many years, you can buy a USB to SD dongle. It’s beyond me why after all of these years Jeppesen has not enabled write direct to SD card capability. ### 1/5 — USB C Support *2024-04-06* It should be so easy to add support to II load the downloads to a USB drive. Please add support, no need Bad Elf anymore. Just like a computer does that, a mobile device should be able to do so. ### 1/5 — Worthless *2024-04-02* Without the ability to download and transfer to an SD card via iPhone or iPad, this app is completely worthless. ### 1/5 — Don’t waste your time *2024-01-25* It really does not work. Shocking Jeppesen would even release this. What is “Bad elf Wombat?” No one knows. Zero support. Given the thousands of dollars for the charts, really shockingly bad. ### 1/5 — What’s the Point? *2022-12-29* If the APP would allow users to just simply use the Jeppesen adapter plugged into an Apple USB-C dongle this app would be useful. ### 1/5 — Still can’t write directly to an SD card *2022-11-24* As others have said his app can’t write directly to an sd card attached to an iPad. Seems like it should be an easy feature to add. The only thing this app supports is the Bad Elf Wombat. I reached out to them and they don’t have a manufacturer. ### 1/5 — What’s the point? *2022-08-31* Bad-Elf Wombat has been sold out for a while and there’s no indication of if or when it will ever be sold again. Why can’t Jeppesen update the app to support direct connection through USB instead of requiring an unavailable third party product? All new iPad Air, Pro, Mini models come with USB C ports which would only need a simple adapter. ### 1/5 — Still has bugs *2018-08-23* I have been using the JDM-Wombat configuration since release. Partial updates of the supplemental databases are still spotty. Need to delete the database history and do fresh downloads. This bug has persisted and is a total deal killer when WiFi is not available. I have talked to support but the software is not fixed. In this day and age. One-star. ## Most critical reviews (10 lowest-rated) ### 1/5 — Useless *2025-11-19* The Bad Elf Wombat has been discontinued, and it is required hardware in order to transfer data from this JDM app to your SD card from your iPad. So this app literally does nothing. When will Jeppesen support transferring updated Nav data to our planes from the most common device we have with us at the plane - our iPADs! It’s kind of unbelievable they are ignoring what seems like their customer’s most common use case. Shame. ### 1/5 — Can’t write to SD cards. *2025-08-15* What is the point of this app? It can only be used to update the databases using a Bad Elf Wombat, which hasn’t been available for many years. Why not update it so it can send the data directly to the SD bard via the lightning / usb port and a standard card reader ? Very disappointing and frustrating! ### 1/5 — Useless *2025-07-15, version 1.11* If the app can’t update the avionics via an SD card, what is the point of the app given the Wombat Elf is not produced. ### 1/5 — No longer supported by Jepp *2025-06-18* Apparently, you need a Bad Elf Wombat to use JDM on iPad. Really?? ### 1/5 — Useless and Worthless *2025-03-16* The product has no purpose….the required hardware interface has not been available for years! Jeppesen could fix this but doesn’t. Hope they don’t ruin Foreflight! ### 1/5 — Add USB SD card support *2025-01-25* This is utterly useless with sd card support ### 1/5 — Outdated app *2024-11-29* Incredible that you need a decice that is not being produced anymore. A shame for a company like Jeppesen ### 1/5 — Does not work *2024-11-26* Cannot actually transfer to an SD card ### 1/5 — Solid 1980’s Technology *2024-10-04* Seriously? Jeppesen doesn’t have an IOS solution where a pilot can download new databases (without “Bad-Elf Wombat” which is an unknown and unavailable device)? As a pilot, we’re required to haul around a laptop? Wouldn’t it be REALLY easy to modify your app so the user can download the databases to a memory card? Up your game, Jeppesen. ### 1/5 — USB C Support *2024-05-25* It should be so easy to add support to II load the downloads to a USB drive. Please add support, no need Bad Elf anymore. Just like a computer does that, a mobile device should be able to do so. ## Most praised reviews (2 highest-rated) ### 3/5 — Great Potential……But Needs One Improvement *2022-04-19* The JDM Mobile app mimics the excellent desktop (Windows) version of JDM very well, and is intuitive and straightforward to use. Downloading database updates to my iPad Pro is fast and easy. I don’t have a Bad Elf Wombat (in fact they are unavailable to buy right now), so I can’t do the transfer to a memory card for updating my Cirrus SR22 avionics. I currently use the JDM Windows version to keep my avionics updated. I tried this Mobile version to see what might be possible when I travel without my laptop (which I use to run the JDM Windows version and transfer update files to an SD card). This brings me to the One Improvement Opportunity: if the JDM Mobile version could directly write the database update files to an SD card that is attached to an iPad, then the update process would be quick, easy and not require another device (i.e Wombat). Attaching an SD card to an iPad is very easy, requiring only a simple plug-in adapter. This would be an elegant solution, and seems “doable” given that the JDM Mobile app is already “sending” the update files via Wi-Fi to a memory card inserted into the Wombat as part of the current process. I know direct Wi-Fi updating of avionics is available in some cases (e.g. using Garmin Pilot Concierge), but it is not robust enough and fast enough, particularly for large update files. As a result, the use of memory cards will be with us for some time. Making it possible to use memory cards directly with JDM Mobile would be a great improvement! ### 3/5 — Need ability to write to SD card with wired adapter *2021-12-06, version 1.9* Please can you add the ability to transfer directly to a lightning/USB C SD card adapter. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
