Claude vs ChatGPT: Which AI Assistant to Use on a Phone

ChatGPT is OpenAI's assistant on a phone: it answers questions, reads photos you send it, generates images from a description, writes in your voice and holds a spoken conversation. The free tier does most of that with limits. Above it sit four paid tiers, from $8 a month to $200, and Google Play now flags the listing as containing advertising.
Specs come from the official store listings and were last checked on 2026-09-07. Developers change pricing and requirements — check the store page before installing.
The ladder is unusually long. ChatGPT Go costs $8 a month, Plus is $19.99, and two Pro tiers run at $100 and $200 depending on how much capacity you want. Separately, usage credits are sold as one-off packs — $4 for 100, $20 for 500, $40 for 1,000 — for people who exceed their plan rather than upgrade it. The free account is genuinely usable: questions, image reading, voice mode and image generation all work, with caps that reset. Prices are US listings and change more often than most subscriptions.
Three things separate it from a search box. It reads a photo — a plant identified as Spiraea, a receipt, a screenshot — and answers about what is in it. It generates images from an instruction, including turning a supplied photo into a different style. And voice mode holds a spoken conversation with named voices and a picker for language and response speed. Longer answers arrive structured, with headings and numbered steps, which is why people use it for training plans and how-to questions rather than short facts.
Two things are worth reading before signing in. Google Play now carries a Contains ads badge on this listing, and Apple's privacy card states that collected data — including location, contacts, search history, user content and usage — may be used for third-party advertising as well as for analytics and personalisation. Google Play counts five collected categories with device identifiers shared onward. On scale, the app has passed a billion Android installs and holds 4.8 across 55.8 million Play reviews. The iPhone build requires a recent iOS release and installs at a moderate size, so the constraint is the account rather than the hardware.

Still the assistant most people should try first: the free tier is genuinely capable, photo understanding is the feature that surprises people, and voice mode works well enough to replace typing. What changed in 2026 is the commercial layer — an advertising badge on the Play listing, a data card naming third-party advertising, and four paid tiers reaching $200. Read that card before making it the place you keep personal questions.

Yes, with caps. A free account answers questions, reads photos, generates images and runs voice mode, and the limits reset rather than lock you out permanently. Paying removes those caps and adds capacity: $8 for Go, $19.99 for Plus, and $100 or $200 for the two Pro tiers.
Identify what is in it and answer about it — a flower named down to the genus, a document read back to you, a screenshot explained. It can also use a photo as the basis for a generated image, turning a snapshot into a different style on request. Both work on the free tier with limits.
Go is $8, Plus is $19.99, and Pro runs $100 or $200 depending on the capacity tier. Usage credits are sold separately at $4, $20 and $40 for 100, 500 and 1,000 credits. Those are US prices bought inside the app; buying on the web is sometimes cheaper.
History is stored against the account by default, and Apple's privacy card lists user content among the data collected and linked to you. Settings control chat history and training use, and a temporary chat mode exists for conversations you do not want kept — worth finding before typing anything sensitive.
Google Gemini is deeper inside Android and Google's own apps, with no in-app purchases on its Play listing. Claude has no advertising badge and a narrower data card. Meta AI is free but collects the most of the three. The differences now are commercial rather than conversational.
