TurboTax offers a mobile app for Apple and Android devices. You can use the app to complete all your tax forms or simply snap a photo of your W-2 so the information can be imported into your tax forms. You can also upload your tax return from last year and connect with a tax expert from your phone if you use TurboTax Live. In addition to its tax app, TurboTax also offers a TaxCaster app to quickly estimate the amount of your tax refund as well as an app to keep track of deductible charitable donations called ItsDeductible.
