Voice input in expense trackers is almost always a premium feature. The apps that have it usually lock it behind a monthly subscription. The ones with a free tier either do not include voice, or include a trial that disappears after a few weeks.
The good news: at least one app - DrakeAI - offers truly unlimited free voice logging, and a few other workarounds exist.
This is frustrating because voice input is most useful for people who are trying to build a logging habit - and those people often cannot or do not want to pay before the habit sticks.
Here is where things actually stand on free voice logging in 2025.
The honest reason is server cost. Speech-to-text processing uses more compute than text parsing. Each transaction costs a fraction of a cent more than a typed entry. At scale, this adds up, so voice becomes a premium feature.
Platform: Android (iOS coming soon)
Price: Free tier available
Voice: Unlimited, not paywalled
Bank connection: Not required
DrakeAI's free tier includes unlimited voice logging. Voice and text input are both available without a time limit or trial. No bank account needed. The microphone button is in the main chat interface alongside the text field.
Platform: iOS, Android, web
Price: Free tier available
Voice: Via OS keyboard dictation (not native)
Bank connection: Not required
Not a dedicated expense app, but Notion's free tier works with your phone's built-in voice dictation. You tap the microphone on your keyboard and dictate into a database template. Requires initial setup but is genuinely free.
Platform: iOS, Android
Price: Free
Voice: Via Google Assistant
Bank connection: Not required
Voice input via Google Assistant is free. Say "Hey Google, add to my expenses: coffee four fifty" and it creates a note. Not a proper tracker, but it works for minimal needs.
Platform: iOS only
Price: Free
Voice: Via Siri (OS-level)
Bank connection: Depends on target app
If you set up a shortcut that logs an expense in a supported app, Siri activation is free. The expense app itself may require payment, but the voice trigger is free OS functionality.
The free tier covers unlimited logging via voice or text, plus a set of daily Q&A queries. There is no monthly cap on voice expense logs.
The paid tier adds more Q&A queries and deeper analytics. Voice logging itself does not require payment.
The research on habit formation is consistent: friction at the critical moment kills habits. For expense logging, that moment is right after making a purchase.
If voice logging is paywalled, the user faces a decision at that moment: pay or skip logging. Many will skip. Free voice expense logging removes that barrier. You log the expense in the natural way - by speaking - without a paywall interrupting the behavior you are trying to establish.
If you want to get started today without spending anything:
No payment required, no trial to remember to cancel.
If you build a habit over a few months and find voice logging genuinely valuable, paying for a better overall experience is easy to justify. The free tier is designed to let you reach that conclusion naturally.
