I had been using it with great results for a while, and then for some reason now it simply quits as soon as I launch it. I have tried uninstalling and reinstalling, restarting the phone, etc. But the app simply will not run. I would like it to be fixed. Any thoughts? ### 2/5 — . *2021-09-20* Tolle App aber sollte dringend mal ein Update bekommen besonders für die Auflösung des iPhone 12/13 Pro Max.... Korrigiere auf 5 Sterne sobald sich darum mal etwas gekümmert wurde. ### 4/5 — Export to PDF *2021-07-21, version 2.4* Can the option to export to a PDF file be added? ### 3/5 — How do I contact the creator of this app? *2019-11-24, version 2.4* This is an excellent app, very useful. However I’d really like more information about the app eg what do the numbers mean at the side of the graph are they seconds or minutes? And how do I use the app eg where can I store data and how to send by email? If the creators of this app are reading this, I’d still really like some help with my questions here. How do I contact you, do you have an email address please? Many thanks ### 2/5 — Great app...but... *2018-09-07, version 2.4* It is great app for recording vibrations and it is very sensitive, but it constantly crashes during playback of recording. Wasted money! ### 4/5 — Very Cool - Even cooler when there are actual stats *2015-04-14, version 2.3* Someone asked for a use-case - ie why would I want this app? Night photography: How still really is your camera for a long exposure shot? Take a measure, adjust as needed. This is a great app and fun. Would love see some stats that can viewed and saved for later comparison. The Roller Coaster Physics app is along the lines of this app, and now allows you to email a full run of the measurements for later loading into Excel or other app. Looking forward to a new version ### 5/5 — Outstanding *2013-12-10, version 2.3* Outstanding app. The streaming feature works incredibly well. Support by the developer is excellent also. ### 5/5 — Cool *2013-08-04, version 2.3* I love the app but it is actually supposed to be called Seismograph ### 4/5 — Needs upgraded display support *2013-02-27, version 2.2* Needs to be compatible with the new iPhone 5 and iPod touch. Otherwise, GREAT!!! ### 2/5 — Could be better :-/ *2012-12-09, version 2.2* I like the app but it has some problems: - It does not fully support the iPhone 5 bigger screen. - It crashed a few times. - The top left button does not any effect on the app. It does look like a on/off button but it has no effect on the behaviour of the app. ### 2/5 — Works well, but crashes a lot *2012-11-09, version 2.2* Nice UI and functionality, but the app exits itself a lot. Arguably better than free apps available. Don't waste your dollar. Purchased 9 Nov 2012 Using iPhone 4s, iOS 6.0.1. ### 3/5 — Nao *2012-04-14* Enquanto era de graça, até q valia o tempo perdido, mas pago nao recomendo. Ainda bem q peguei antes d virar pago. ## Most critical reviews (10 lowest-rated) ### 1/5 — Export functions don’t work *2021-04-26, version 2.4* Export functions don’t work App shuts down with no error message. ### 1/5 — Crashes *2020-10-12, version 2.4* Crashes so much, app needs to be updated. Waste of $2 ### 1/5 — Doesn’t let you export data *2019-04-07, version 2.4* Having just bought the app to use for a project, manage to record necessary data, but when trying to export csv via email crashes and won’t let you send email. ### 1/5 — No good *2019-02-24, version 2.4* This is really a terrible application. I want my money back. I am a specialist in earthquake engineer and this app is useless ### 1/5 — No way to get data out of the app *2018-08-29, version 2.4* If you have a lot of data the app will just crash- totally useless. We had an earthquake in Los Angeles about an hour ago, and I wanted to show off this app, but it only crashes when you try to look at a history file that recorded for only 13 hours. It won’t email or send to documents which does nothing. I tried accessing the data from my MacBook Pro using an iPhone backup program, and the app no longer will allow access to its folders. Wish I could see the data. If the developer wants to reach me feel free to email me. I like the display screen but too bad it didn’t perform when I needed it to. ### 1/5 — Crashes *2014-05-26, version 2.3* 5s latest iOS and this crashes if you attempt to look at a recording. Controls non responsive e.g press record and there is no indication if it's recording. No scale on seismograph. All in all rubbish. ### 1/5 — Very poor implementation. *2014-02-11, version 2.3* I know there are only two other reviews that give high praise, but one must be from the developer. This seismometer only displays one axis at a time…. a bit useless if you a trying to record all 3 or even just two for that matter. The streaming feature SEEMS to work well…. except it only displays the Z axis even if you select the Y or X axis. It will ONLY stream the Z axis. Since earthquakes and other shaking rarely occur on a single axis, and most are rarely on the Z axis (up/down), this is completely useless. Allow displaying/recording of multiple axis, and allow the stream to display ANY other axis besides the Z axis, and it will be a GREAT app. ### 1/5 — Falta mejorar *2013-01-30, version 2.2* Se tendría que poder usar con la pantalla apagada. Hay que mejorarla mucho mas. ### 1/5 — Insensitive *2011-02-18, version 2.0* That about sums it up. The accelerometer capabilities of the iPod/phone were easily displayed in the old version. Now i have to shake the thing for results. ### 1/5 — seismometer *2011-01-04, version 0* malo solo toma las vibraciones de la superficie donde uno se apoya, no mide ni entrega información sobre intensidad de las oscilaciones. Inservible ## Most praised reviews (10 highest-rated) ### 5/5 — Best app *2026-07-05, version 2.4* Of all seismometer apps ### 5/5 — Awesome *2017-09-30, version 2.4* Thanks for updating for iOS 11 support! Been a fan of this app. Even though I use it once in a while for fun, it is quite useful for detecting vibrations. I can actually see my heart beating now if I put my phone up to my heart. It's really sensitive. I like it!! ### 5/5 — Great app, and now works on IOS11! 😁😁 *2017-09-27, version 2.4* Great app, amazing how sensitive it is. Graphics are cool and I like using the UDP streaming feature. 😊 Thanks very much for updating. ### 5/5 — Thanks developer *2017-09-26, version 2.4* Thanks for keeping the app alive throughout the updates ### 5/5 — Best ap *2017-06-07, version 2.3* This ap is great for apartment vibration. The bezel filter is perfect for detecting floor vibration, and the ability to save and export vibration recording is perfect for proving to apartment staff that something should be done. Gentlemen. Apple has declared that this app needs to be updated. I really like the app and request that steps be taken to modernize it so we can all continue to use it. ### 5/5 — Seismometer *2015-12-17* Hi, diese App ist extrem praktisch im Bereich HIFI. Dabei ist für die gute Tonqualität speziell beim Plattenspieler aber auch beim CD Spieler das Vermeiden von Schallübertragungen extrem wichtig. Mit dieser App kannst du diese Übertragung ganz einfach prüfen und bewerten. Somit nicht nur Spielzeug sondern sehr hilfreich! Danke Leider etwas schwierig, Anregungen an den Entwickler zu senden da er keine Mauladresse hinterläßt ### 5/5 — Sujerencia *2015-08-20, version 2.3* Seria muy util poder establecer unos limites apartir de los cuales hacer sonar una alarma Gracias ### 5/5 — Mr. *2014-12-14, version 2.3* This is a very cool, useful and professional app, worth every cent! I love the many settings and great functiions. Everything runs really well my iPhone4. Supersensitive. Highly recommended... ### 5/5 — Great app *2014-09-27* Best seismometer app IMO ### 5/5 — Will pay more up to $ 5.00 easy If ??? *2014-04-02, version 2.3* Would like to have X Y Z on different pens. Also to have numbers on the chart. One more request have a adjustable limit marker and if reading is detected Above set limit optional audio alert. Other then this wish list the app is great . Yes, this is exactly what I would do and want. This app has the best animated PIN draw then all the rest available. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
