Bolt is a small, distraction-free VoIP calling dialer app replacement for Android


Developer: BoltDownload: Android
Genre: VoIP CallingPrice: Free

Chat and VoIP-calling apps are a great way to get past wireless carriers' awful pricing. Seriously - does it really cost this much to beam a few bytes of data in the form of an SMS/MMS over your hyped cellular network, dear telecom? If we're paying for data service, we might as well just use that instead - which is what millions of users do nowadays. However, those messaging apps from feature bloat, resource hunger, and a severe lack of simplicity. 

Even worse, all your friends use different apps, and staying in touch with everyone means keeping several apps listening for signals at once, which clogs up your device. It also means launching a different app depending on who you want to call or chat with. The folks at Bolt saw through this and chose to walk against the grain. Bolt is a VoIP app that functions as a simple, distraction-free dialer replacement. It integrates with your phonebook in the same way your stock dialer does, but there's an important difference. Calls to and from contacts that don't have Bolt installed will be routed over your regular wireless network and charged accordingly. Calls to and from fellow Bolt users run through your data connection. No app juggling, no sticker packs, no memory hogging. Just sweet VoIP calling, the way it should be. 

The developers claim Bolt compresses voices into just 60KB of data per minute, which means you'll get a whole lot of call time regardless of your data plan. Fancy what you're seeing? Bolt is free, but it's only up for Android right now. The eventual iOS version will be released when it's done.

Very good, we needed something like this. An app only for VOIP. Installing...

I am really curious how VoIP works when there is limited bandwidth. Please post your experience using the app in low bandwidth circumstances.

Voice compression is good.

Skype's been great with a fixed fee Skype out unlimited. Skype was troublesome on Android at the start of last year, because it would send headset sound to the speakers instead etc etc. The next build fixed that, but brought other problems. All sorted out in the more recent builds. Feature improvements I'm missing in Skype are those that WhatsApp incorporates; SMS type activity, atttachment of photos and films taken with the device.

I like Hangouts dialer for the fact that you can make a call to anyone without using voice plan minutes, whether they have hangouts or not. It works great on the T-Mobile $30/month unlimited text, 5GB high speed data, 100 minutes vocie plan and you have a Google Voice number as your primary number and using the Hangouts dialer to send and receive all calls.

I want a WiFi calling app, that uses your existing phone number. Much like the app that TMO uses. Don't want Google voice, don't want another number. Anyone?

MagicApp... For $30/year you get to transfer your existing number and make unlimited VOIP calls to any US or Canadian phone number. The App is fairly new and might not be bug-free yet but it works great.
