Doch leider erhalte ich die komprimierten Videos immer wieder nur im Querformat. Ich kann die Videos leider nicht drehen. Schade. ### 1/5 — Waste of money *2020-07-20, version 3.0* Didn’t work, don’t bother ### 1/5 — Crashes *2020-06-10, version 3.0* Keeps crashing straight away. Can’t use it at all. Very disappointing ### 1/5 — Does not work, don’t waste your money!! *2020-05-14, version 2.5* The app does not work at all. Every time I select a file to compress the app shuts down. Hasn’t worked for me one time. I would have been better off setting $2.99 on fire. ### 1/5 — Can’t access my original videos *2020-05-14, version 2.5* App shows only 6 of my 293 original videos. Emailed developer but no response. ### 1/5 — Crashes *2020-04-26, version 2.5* When the app worked, it worked well. Now all it does is crash after you've selected the video you want to slim. I'm now looking elsewhere for a reliable app ### 2/5 — Don’t Buy—No Longer Works *2020-04-21, version 2.5* I got this app a couple years ago and tried it out recently. It doesn’t do anything—when I try to add a video, it takes me right out of the app. A waste of time. ### 1/5 — This is awful what a waste *2020-04-18, version 2.5* This automatically shuts every time I try to upload a video. So frustrating. I can’t believe how bad this app is and that I paid for it. ### 1/5 — Video Diabled *2020-04-11* While merging n slimming video is invisible n only audio is available ### 1/5 — Keeps crashing *2020-02-02, version 2.5* I cannot even upload my video. The app keeps crashing every time I attempt to select my video. ### 1/5 — Worthless! *2020-01-18, version 2.5* The app always crashed after the second or third file added. I had to compile in iMovie and compact in Video Slimmer. The compilation feature is greenscreen. Worthless! Don’t buy this app! ## Most critical reviews (10 lowest-rated) ### 1/5 — Do not buy - only half working, no support *2022-06-01, version 3.0* Support website doesn’t work anymore, which is bad as the app doesn‘t work as advertised. It compresses the videos, yes. But the control and settings over the compressions don‘t work as advertised. Despite being able to select different sizes, I just managed to get videos in 1920 or 536; none of the other settings seem to have any impact - they just produced 536px videos. Same with quality settings - don‘t seem to have my impact. This app is pretty useless for the money. ### 1/5 — Overcharged do not purcahse *2022-04-01, version 3.0* Do not buy this app unless you are prepared to pay $20, which is what I was just charged. Not happy. How do I get a refund? ### 1/5 — Total waste *2021-10-15, version 3.0* No instructions or support ### 1/5 — No vale la pena *2021-10-08, version 3.0* De todo que no es aplicación gratuita, me dejo arreglar solo un video 😡 ### 1/5 — USELESS *2021-09-14, version 3.0* Downloaded app. App says ‘slim now!’ But when you click on it you get a blank screen and NO option anywhere to add your video anywhere. Quite bizarre. Doesn’t work. Waste of my time. ### 1/5 — No good *2021-09-08, version 3.0* Rotates videos for no reason. I cannot control when to rotate. Also….the support link is not working. Don’t mind the cost….if it works but now I gotta go to Apple to get my $4 back! So annoying…… ### 1/5 — Paid app. Doesn’t work *2021-08-09, version 3.0* When it works it’s great. However it seems to go down for days. No response from customer support ### 1/5 — Not good *2021-06-18, version 3.0* This app slimmed video but NOT enough to email a simple video. Also I can’t get my money refunded. ### 1/5 — Doesn’t work well with latest iOS *2021-02-14, version 3.0* Used to work perfectly. Now with latest iOS on iPhone 12 Pro Max I can’t select videos to merge, and I can’t see the “choose from” list thumbnails, and I cannot add videos nor can I rearrange them. Completely disappointed that this paid app is no longer functional. ### 1/5 — I dont know *2020-12-21, version 3.0* Well i just noticed they have been an upgraded in the app like 10 mins ago and coincidentally thats the time ive been trying to slim some videos and as soon as i click on slim it kicks me out of the app i already deleted it and installed it again but same problem. Whats going on? ## Most praised reviews (10 highest-rated) ### 5/5 — 神アプリ *2026-04-15* 最高です！おもわずレビューしました！ ### 5/5 — Perfect video compression tool *2022-11-11, version 3.0* A large choice of compression options depending on quality/size preferences. Compressed files are saved to Photos app. Eg. A 280Mb 90second video was compressed to 68Mb with NO visible deterioration in quality (1080p) in 14 seconds. I’ve had no problems with this app, it’s perfect for my needs. ### 5/5 — Super useful. Always a great job. *2021-11-11, version 3.0* 11/11/21 I’ve used this app for a long time. It is straight forward, easy to use, and reduces the original video to an impressive small byte size, and yet it retains a very close quality to the original. I am often surprised that I can email videos after using this. Of course it depends on your original video size and length. I have never had any problems with it. I hope that you will get a lot of value as I do. I use it as a regular guy who likes video and photos and to edit and share. I use this on iPhones. Now it is an iPhone 12, with no problems. For those having problems, hang in there, there is likely a good explanation to resolve them. This is a great and useful app. Cantact them via the website. Two suggestions for improvement. 1 When you open the video selection panel at the beginning, please show the current value of the size of the file. 2 Also, here, please show which files have already been compressed. Both of these facilitates deciding which file to possible try a second compression, should it be worth it. With many apps using different schemes of ordering the apps (biggest to smallest byte size etc or the reverse) it is not easy to know which was the most current file. Thank you for all the great value that I have had. California ### 5/5 — おすすめ *2020-05-14* 簡単だし、素晴らしい！ ### 5/5 — Using it for 5 Years and it’s Reliable & Awesome *2020-05-09, version 2.5* I’ve been here since the start ... on Day 1 of the release of iPhone 1 - I got there early and waited for this new place called The Apple Store to open. When it did open, I walked in knowing exactly what I was doing; because I do my homework. The reason I’m holding an iPhone 8 Plus over TEN YEARS LATER however, is because (no matter how many times I’ve wanted to scream at the decisions they make) I’m a fiercely loyal customer who knows it’s best to stick with a winner. And As Far As Apps Made To Slim Videos Go: This Is A Slam Dunk! • It Has Never Crashed in Over Five Years Use • It’s Handled Every Video I’ve Thrown At It • You Can Customize The % Of Size Reduction • You Can Customize The Video Dimensions • It’s Fast, It's UI Is Perfect And It’s A Beast! Highest Recommendation!! ### 5/5 — Super! *2020-05-01* My most usefull app! ### 5/5 — Fast Compression Nice Results *2020-04-25, version 2.5* Thanks Video Slimmer ### 5/5 — Très pratique! *2020-03-10, version 2.5* Facile d’utilisation. Nous pouvons choisir la compression en plus! Parfait ### 5/5 — Great app *2019-11-27, version 2.5* I've been using this app to trim videos to put into Evernote. It merges and trims the movies and keeps very good quality. ### 5/5 — Worked well for me *2019-11-24, version 2.5* I was able to compress a couple of 230MB videos down to 11MB for emailing, just now. Perfect. I see it also rotates videos which have been filmed the wrong way round - that’s going to be useful! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
