Any chance we'll see IPv6 support? ### 4/5 — Great ipv4 subnet calculator *2015-06-28, version 1.4.0* With the latest update, the app can finally be used again. Thanks for that. Would be great to add ipv6 calculator. ### 4/5 — Just in time! *2015-06-28, version 1.4.0* Thank you for updating the app, I was close to deleting it because of the disappearing slider bug that's been around for almost forever! ### 2/5 — Broken *2015-05-28, version 1.3.5* This used to be my goto subnet calculator. I gave them a chance to fix it after the iOS update broke it. Too late now. Bye. ### 4/5 — I Love This Ap! *2015-04-18, version 1.3.5* I wished I wrote a review a long time ago but did not for unknown reasons. I use this at work very often and it is Great. Upgraded to IOS 8.3 and there are now issues. The Slider Bar that changes the SubNet is there for a second and then goes away... This was the reason that this Ap was the BEST and now it is gone. Please Update this ap! I paid the $0.99 Thank You! ### 3/5 — Broken in iOS8? *2015-04-14, version 1.3.5* The slider does not work on iOS 8.3 on iPhone 6. This has been an invaluable tool for years. I'd love to see it work again. ### 5/5 — Great app!! *2010-02-26, version 0* I use this often to check my work. Simple, easy to use, and a great price mades this an app every netadmin or sysadmin should have! ### 5/5 — Schnelle IP Masken Berechnung *2010-02-15, version 0* und toller Produktivitätsgewinn, indem man asubnet Links ins Adressbuch packen kann. Habe somit zu jedem meiner Kunden gleich das passende Netz mit Berechnung parat. Echt Klasse. Slider funktioniert ohne Probleme seit iPhone OS 3 und Null Abstürze von Anfang an. Weiter so. ### 5/5 — Bellisimo *2009-10-19, version 0* Simple. Perfect! Well done. ### 5/5 — This rocks! *2009-10-16, version 0* You type in the IP address and theres a slider bar to adjust your network bits. Everything is calculated. The info button lets you change to hex. A nice addition would be a filed to put in hex to convert that. Still waiting for a telnet app.... ### 4/5 — Great little program. Tad bit buggy? *2009-09-15, version 0* I like it - just what I was looking for and needed, and am way too lazy to calculate. However, the slider seems to get stuck often, and in fact, not accept input for seconds at a time (tried on 2 phones) unless you 'let it be' for a bit.Otherwise, it's nice, and free. ## Most critical reviews (10 lowest-rated) ### 1/5 — Great app *2015-05-22, version 1.3.5* The developer just need to spend some time to make all features, specially the slider, to work with iOS8.3 ### 1/5 — Broken app *2015-05-15, version 1.3.5* I know my iPhone gets quirky at times but the slider bar at the bottom has disappeared. I just happened to rebuild the phone and reinstall apps but it still is missing. Not a very useful app right now ### 1/5 — Slider is broken in IOS 8.3 *2015-04-27, version 1.3.5* I've been using this app for years and years and loved it.. Now the slider bar is broken making the app useless. Please fix! ### 1/5 — Erro fatal! *2010-12-22* O programa é bem prático e útil. Eu faço esses cálculos de cabeça e ainda assim prefiro o programa! Pelo menos preferia, fui inventar de colocar 0.0.0.0 na mascara e o programa nunca mais funcionou. Comuniquei o erro mas em três meses desde que comprei o programa não teve atualizações. O autor abandonou o programa... e eu perdi um dólar com ele! ### 1/5 — Crashes on os 4.1 or higher *2010-12-06, version 0* Did Work before later updates ### 1/5 — asubnet *2010-04-25, version 0* Worked for about three attempts then stopped altogether. Will not load at all. Pretty disappointed because it would be a great app to have handy. Hope an update comes soon to fix this bug. ### 1/5 — Bug *2010-02-09, version 0* Bug du téléphone après 2 ouvertures et depuis l'application ne fonctionne plus!!! ### 1/5 —  *2009-12-27, version 0* Stürzt mittlerweile nach dem Start direkt ab! ### 1/5 — Calcul iPhone 3.0 *2009-08-03, version 0* Ne fonctionne depuis mises a jour 3.0 ### 1/5 — Sehr schönes Tool, wäre da nicht der Slider für die Netzwerkbits *2009-07-04, version 0* Besagter Slider hängt nämlich meistens fest und bewegt sich erst nach zig Versuchen, ihn zu bewegen. Daher nur 3 Sterne. Aber ansonsten ein recht nützliches Tool für alle Netzwerker. /Edit: Auch in der neuesten Version hängt der Slider und dass die Beschriftung unter ihm angebracht ist, hätte der Autor nun auch schon längst verbessern können. Zusätzlich sind die Buttons am unteren Rand sehr sehr schwer zu treffen. Fast kein Tap wird ordentlich registriert. ## Most praised reviews (10 highest-rated) ### 5/5 — Invaluable *2016-11-01, version 1.4.1* I use this for double-checking my wildcard masks for access lists & making sure I didn't fat finger or flub any subnetting. Super handy for VLSM. ### 5/5 — It's back! Thank you! *2015-06-27, version 1.4.0* Like many I used to use this tool every day but have been disappointed as it didn't work with IOS 8.3. This latest update fixes the slider bug and gives it a RetinaHD overhaul. All I can say is bless you app developers. Great job. I have my go to tool back. ### 5/5 — Great update *2015-06-27, version 1.4.0* Great update that restores functionality and brings iPhone 6/6+ native resolution. ### 5/5 — Very useful app *2014-04-03, version 1.3.5* Quite specific functionality, but does exactly what I need. ### 5/5 — Einwandfrei *2012-02-01, version 1.3.1* Das APP Macht was es tun soll. Einwandfrei, nur zu empfehlen. ### 5/5 — Con ultimo aggiornamento *2012-01-13, version 1.3.1* Perfetta ora che è stata aggiornata ### 5/5 — Alles bestens! *2011-11-14, version 1.3.0* Finde die App für ihren Funktionsumfang und ihren Preis sehr gut ! - schön klein mit ca. 0,2MB - übersichtlich aufgeräumt - sehr verständlich - einzig das Ändern der Netzmaske ist für große Finger etwas schwierig ### 5/5 — Perfekt!!! *2011-11-02, version 1.3.0* Ich nutze diese App regelmäßig und finde sie großartig. Als Verbesserung würde ich mir die Wildcard Anzeige unter der normalen Netzmaske wünschen. Dann hat man nämlich alles auf einen Blick und muß nicht immer über Info auf Wildcard wechseln. ### 5/5 — Must have! *2011-06-14, version 1.2.1* It's a must have app for network administrator! ### 5/5 — Saved my butt! *2010-09-23, version 0* I'm working for a client who loves 22- and 23-bit subnet masks. The calculations were starting to melt my brain! This app greatly simplifies my work. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
