Say the same thing, land it better. ToneFix rewrites your texts, emails, and Slack messages in seconds, on your iPhone, without changing a single fact. Free to download. Nothing you write ever leaves your device. No account. No cloud. No subscription. WHAT IT DOES Paste a draft or use the keyboard and share sheet anywhere you type. Pick a tone, pick a channel, and ToneFix rewrites it while keeping your names, numbers, and dates intact.

PRESETS AND CUSTOM TONES Stack your favorite tone, intensity, and channel into one tap. Build your own tones for the exact situations you deal with โ the tough client, the group chat, the weekly update.

Tag it, search it with Spotlight right from your home screen, reuse it, or export your history to CSV. TONEFIX PRO Free gets you everything above, with 2 of your own presets plus every built-in preset. ToneFix Pro is a one-time $4.99 purchase, no subscription, and unlocks: โข Custom tones and Learn My Voice โข Unlimited presets โข iCloud sync across your devices PRIVACY AND REQUIREMENTS ToneFix runs on Apple's on-device Foundation Models โ your text is processed on your iPhone and never sent to a server. AI-powered rewrites require Apple Intelligence (iPhone 15 Pro or later, and all iPhone 16 and iPhone 17 models). On other iOS 26 devices, ToneFix still works with a built-in rule-based rewriter that handles Shorter, Clearer, Remove Fluff, and More Confident, and cleans up the rest. Built for iOS 26 with an accessible, native design: full VoiceOver support, Dynamic Type, and Reduce Motion respected throughout. No account. No ads. No data collection. Just better messages, sent from wherever you already are.

Verdict
