The same AI girlfriend product can feel completely different on iPhone, Android, PC, or in voice mode. This guide pulls every device-specific angle into one place: what to optimize for, how web apps compare to app stores, and where voice fits in 2026.
Secret Stars runs as a mobile-first web app — same characters, memory, and chat on every platform. Open secretstars.app, sign in, and you get 100 free messages per 30 days. Characters span realistic and anime styles.
AI girlfriend app on iPhone (iOS)
What works on iPhone: touch-native layout, fast responses, chat that feels like a messaging app (not a form), and Safari support so you are not forced through the App Store.
Why web apps matter on iOS: many companion products skip strict App Store review or ship faster as PWAs. You can Add to Home Screen and get full-screen, app-like launch without a store listing.
Add Secret Stars to your Home Screen (Safari)
- Open secretstars.app in Safari
- Tap the share icon → Add to Home Screen
- Confirm the name → Add
iPhone tips
- Landscape helps for longer threads — more history and a wider keyboard.
- Keep Safari updated — web app performance improves noticeably on recent iOS.
- Notifications: enable per-site if the product supports them.
Other iPhone options (quick)
- Replika — native iOS app, single-companion depth.
- Character.AI — huge library; heavy filters for romance.
- Candy AI — strong visuals; adult modes for adults.

AI girlfriend app on Android
What works on Android: Chrome performance, Add to Home screen, and flexibility when something is not on Google Play (policy-driven — companion apps often distribute via web).
Add to Home Screen (Chrome)
- Open secretstars.app in Chrome
- Menu (⋮) → Add to Home screen → confirm
Android tips
- Prefer Chrome over alternate browsers for the smoothest PWA behavior.
- Notifications: Chrome can grant them per site — useful if your companion app supports nudges.
- Sideloading: possible on Android for APKs; only use sources you trust.
- Mid-range phones: LLM work is server-side; connection quality usually matters more than CPU.
Play Store vs web
Do not treat “not on Play” as automatically bad — many serious companion experiences use the web to avoid store constraints. Secret Stars is built that way on purpose.
Other Android options (quick)
- Replika — Play Store native app.
- Character.AI — Play Store, large catalog, filter-heavy for girlfriend-style chat.
- Candy AI — mobile web, visual and adult-oriented positioning.
AI girlfriend on PC (Windows & Mac)
Desktop is underrated for companionship: full keyboard, more transcript on screen, fewer phone notifications competing for attention, and a browser tab can feel more private than a home-screen icon.
What to look for: works in Chrome / Firefox / Safari without a separate installer, smooth scrollback, and inputs that handle long messages.
Secret Stars on desktop: discovery uses click-through cards (same matching logic as swipe); chat and persistent memory match mobile. Works on Windows and Mac with no download.
Windows: Chrome or Chromium Edge are solid defaults. Mac: Safari or Chrome both work well.
PC vs phone — which is better?
| Use case | Lean toward |
|---|---|
| Long, thoughtful typing | PC |
| Late-night quick check-ins | Phone |
| Touch-first discovery | Phone |
| Focused session, fewer distractions | PC |
Many people use both — desktop for depth, mobile for availability.
Other PC options
- Replika — Windows desktop app for a single evolving companion.
- Character.AI — browser, massive variety.
- Candy AI — browser, visual/adult positioning.
AI girlfriend voice chat
Voice adds tone, rhythm, and presence text cannot fully replace. In 2026 the category is still catching up: latency, voice consistency, expressive TTS, and cost remain hard problems.
Rough benchmarks: under ~2 seconds of delay feels conversational; much more than that breaks flow.
Who ships voice today: Replika has voice calling (usable but not perfect latency/expressiveness). Character.AI experiments with voice; quality varies. Specialty voice-first apps move fast but often trade away depth.
Secret Stars today: text-first — full personality and memory where the stack is strongest. Voice across the industry is improving quickly; building a real bond in text first still matches where the best character work lives.
Evaluating a voice companion
- Same memory and context in voice as in text?
- Stable voice identity session to session?
- Emotion reads as warm/playful/teasing, not generic assistant?
