## Apollo (formerly AIDA)

Apollo is a multi-model AI chat app for iPhone and iPad, distributed on the Apple App Store and developed by Quillbound Studios Ltd. The listing is the same App Store entry that previously carried the name AIDA, which means the product was rebranded rather than retired: people who installed AIDA can expect the same style of assistant experience under the Apollo name. Its central pitch is choice. Rather than committing to a single vendor, the app lets you switch between models from OpenAI, Anthropic, Google, and others, which is useful when you want to compare how different engines handle the same request.

Functionally, Apollo behaves like a general-purpose assistant. It generates marketing copy, product descriptions, blog and essay drafts, social posts, and business documents, and it can also handle routine text chores like grammar correction, summarization, and translation. The app documentation also mentions spreadsheet-creation usage and analysis-style tasks, so the intent is broad productivity rather than a single niche. Features include customizable prompts and settings for advanced users, the ability to save favorite responses, and the option to generate multiple variations of a creative request at once. The interface is designed to be approachable for people who just want a chatbot, with deeper controls available for power users.

Two things are worth flagging. First, the app is free to download but offers in-app purchases, so heavier usage or premium features may sit behind a paywall. Second, Apple's listing carries a 13+ age rating and warns that AI/ML models can produce inaccurate or offensive content and that users should not enter personal information; output should be reviewed rather than trusted blindly. Ratings on the store are strong, with a 4.7 average across roughly 189 reviews.

**Pricing & Plans:** Free to download with in-app purchases. The App Store listing labels Apollo as free with in-app purchases rather than listing a subscription price, so any paid tiers are handled inside the app.

- **Multi-model access:** Chat with models from OpenAI, Anthropic, Google, and others in a single app instead of juggling several separate assistants.
- **One-tap model switching:** Move between AI engines mid-conversation to compare tone, detail, and reasoning for the same prompt.
- **Custom prompts and settings:** Save reusable prompts and tune parameters for recurring workflows such as writing, coding, or research.
- **Saved responses:** Bookmark answers you want to keep so they are easy to find again later.
- **Broad task coverage:** Handles copywriting, creative writing, social posts, business documents, summarization, grammar fixes, translation, and code help.

**Strengths:** Access to several major AI models from one app, which makes side-by-side comparison simple.; Strong user ratings (4.7 average across roughly 189 App Store reviews).; Custom prompts, saved responses, and multi-variation generation for repeat workflows.; Runs on iPhone, iPad, and Vision, so the same assistant travels with you.

**Limitations:** Free download with in-app purchases means premium access and heavier usage likely require payment.; Only available on Apple platforms, with no Android or web version offered in this listing.; AI/ML models can produce inaccurate or offensive output, so responses need review before use.

## ChatOne

ChatOne takes the idea of "one prompt, many answers" and turns it into a practical everyday workspace. You type a question once, and the platform fans it out to a set of supported models such as GPT-4o, newer GPT-5.x variants, Grok 3, Grok 4.1 Fast and Kimi K2.5. The responses stream back side by side so you can judge which model gave the clearest, most accurate or most creative answer, without paying for and switching between half a dozen separate AI subscriptions.

The interface is intentionally lightweight. Free trial users can run up to 6 models at once with a small credit allowance, while paid credit packs and monthly subscriptions raise the ceiling to 10 simultaneous models and unlimited queries. Plan tiers differ mainly in how many models can run in parallel, how many queries you get, and whether support is standard or priority. Because models are added as they are released, the supported list changes over time.

ChatOne is a third-party aggregator and is not affiliated with OpenAI, Anthropic, Google or xAI; model names are used descriptively to indicate which engines you can query through the app. It is best understood as a comparison and convenience layer for people who already use AI chat daily and want faster model selection.

**Pricing & Plans:** Freemium with a free plan (limited credits, up to 6 models at once), discounted credit packs, and monthly subscriptions — roughly $15.99/month for Basic (unlimited queries, 6 models) and $34.99/month for Premium (10 models, priority support), with periodic promotional discounts.

- **Simultaneous multi-model answers:** Send a single prompt to several models at once and read the replies in parallel, which makes model comparison fast and concrete.
- **Broad model coverage:** Access OpenAI GPT-4o and GPT-5.x variants, Claude family models, Gemini, Grok 3 / Grok 4.1 Fast and Kimi K2.5 from one account.
- **Add or remove models per chat:** Choose exactly which models participate in a given question, so you can run a cheap two-model check or a wide ten-model sweep.
- **Credits and subscription tiers:** Start on the free credit plan, then move to discounted credit packs or unlimited-query subscriptions as your usage grows.
- **No separate provider logins:** You only need a ChatOne account — there is no need to hold individual API keys or subscriptions for each underlying model.

**Strengths:** One prompt produces answers from many models, which makes quality comparison genuinely practical; Free plan with credits means you can test the multi-model workflow before paying; Subscriptions offer unlimited queries and up to 10 parallel models at a moderate price; No need to manage separate accounts or API keys for each underlying model

**Limitations:** Because it aggregates third-party models, output quality and availability depend on the upstream providers; Credit accounting on the free and pack plans can be less predictable than a flat unlimited subscription; Model line-up changes frequently, so previously available engines may be retired or renamed
