Since I didn’t have access to a laptop, I scrounged around the App Store for a solution and stumbled upon this and several others... since this was free and had better reviews than most, I took a gamble. I will say it’s chock full of advertising, which you’d expect with a free app, but it did the job converting my epubs to mobi and did it quickly. It’s not exactly intuitive, and some of it isn’t in English. The conversion itself didn’t take any time, but figuring out how to get the converted book to my kindle took some fiddling. So did trying to close out of some of the ads, which had those gawdawful timers on them. It’s easy to put in kindle, just not readily apparent. Am considering either upgrading this app or buying this persons other, premium app. I have zero idea on what the differences between the two apps might be, but I’d be willing to spend a few bucks just to make the advertising go away. ### 5/5 — Perfect converter! *2020-08-21, version 10.1* I use this to convert my ebooks to mobi for my kindle. Simple and reliable. ### 5/5 — Works great *2020-08-16, version 10.0* Wish I had unlimited conversions ### 4/5 — iPad Pro 适配 *2020-07-28, version 9.1* 我不想一直歪着头去看或拿起iPad Pro去用 OK? ### 3/5 — Tatshxhdhsh *2020-07-26, version 9.1* Gzgsggx ### 5/5 — Works well *2020-07-01, version 8.4* Works well and few ads ### 5/5 — Mobi Conversion is Great *2020-06-23, version 8.4* Mobi conversion is great. ## Most critical reviews (10 lowest-rated) ### 1/5 — The new update *2024-01-07, version 14.3.0* What have you done with the latest update??? It won’t change the covers, the whole app is so complicated and confusing now. Please fix it. ### 1/5 — Rubbish…Useless *2023-03-22, version 13.0* I tried a pdf to EPUB conversion, and it was terrible. Virtually unreadable. I paid £7.99 for the pro version. I’ve asked for a refund but I’ve yet to receive a response. I clicked on the app support button in the App Store, and it was all in Chinese. ### 1/5 — Honestly? Feels scammy. *2022-06-01, version 13.0* I hate to say it, but after buying a month subscription to take care of a set of files that needed o be converted, I never got access to those files. When I try to view the converted file, I’m prompted to upgrade. Even though I, uh. Already upgraded. This is a flagrant ripoff and I don’t know if it’s shoddy coding or what, but I regret spending the $2 on it. ### 1/5 — Extremely poor UI *2022-01-28, version 13.0* One of the worst UIs I've had the displeasure of interacting with. ### 1/5 — No star deserved *2021-03-27, version 12.8* Absolute crap ### 1/5 — Terrible conversion to ePub *2021-02-07, version 12.6* Waste of money ### 1/5 — Candy Crush ads have ruined this! *2020-12-31, version 12.1* This used to be a 5 star app.... now I would give it zero if I could. Candy Crush ads open everytime you press any button within the app and their close options don’t work. There’s literally no way of closing the ads at all, making the app totally unusable. Don’t even waste your time downloading it. ### 1/5 — It gets the job done, with great difficulty *2020-09-20, version 11.0* I don’t mind the pop up ads. The developer needs to make money. But but but… the “x” to close the ad is so tiny and placed so close to the edge of the iPhone 11 screen that it is quite literally impossible to close the ad. I am required to repeatedly force quit the app and restart it, and try again in hopes of loading an ad that has a working close button. This is a huge annoyance over time, and probably not the way the dev intended for it to work. Other than that, the app works. I hope this can and will be fixed. Otherwise, I’ll start looking for another solution. ### 1/5 — Absolutely Nothing *2020-06-18, version 8.4* Did not work at all, very disappointed! ### 1/5 — Free version does not push books to Kindle *2020-06-07, version 8.4* Confusing app, multiple full screen ads in succession, does not appear to do what it claims. Waste of time. ## Most praised reviews (10 highest-rated) ### 5/5 — Okay It As It Lays *2022-10-20, version 13.0* Thanks ### 5/5 — Worked where others didn’t *2022-05-13, version 13.0* Converted files easy that other apps wouldn’t ### 5/5 — 好用 *2022-02-27, version 13.0* 没广告，特别好用，希望继续保持！ ### 5/5 — Love it. *2021-08-14, version 13.0* Love this. So easy to use. ### 5/5 — 卡夫卡 *2020-12-02* 故滴滴滴滴滴滴滴滴滴几滴个x衣服解放日报摒d好很多很多的北京等地本身弟弟放奶粉时间放假放假放假防腐剂不悱不发恢复肌肤不但独家独家顶级的肌肤衬托v让人不过感觉特推出川田悦子他忽然就好呵呵呵呵一声哈哈就像你在哪考启蒙鲁德涅夫男人就掉进去微博哦自己人都会笑看人间福地不想酒店决定不到驾校不想你的酒店肌肤难题不同v一会说吧你的角度都觉得别人佛法肌肤呢 ### 5/5 — Quick and easy *2020-11-28, version 11.0* Quick and easy. ### 5/5 — Idk *2020-11-27, version 11.0* We will see ### 5/5 — Actually works! *2020-11-05, version 11.0* Works with lots of different formats ### 5/5 — Great *2020-10-16, version 11.0* Amazing ### 5/5 — 很好 *2020-10-01* 宇宙第一时间想到的时候就是不开心我还是喜欢一个小时就好啦……你说过的话不记得这件宝贝你有没有发现过这个东西 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
