Plans by platform
OsmO's paid plan names are not identical on iPhone and Android.
Android: Basic and Premium
Basic includes OsmO's core incoming and outbound call tools. Premium adds the dedicated-number and advanced personalization tier. Google Play supplies both localized prices to the app at purchase time.
iPhone: OsmO Pro
iPhone currently uses the OsmO Pro plan. The App Store supplies the localized price and handles the subscription.
Basic versus Premium on Android
Basic includes the six core capabilities shown in the Android app:
- Incoming AI call handling
- Outbound AI calls
- Assistant voice choices
- Custom call-handling rules
- Urgent-call handling
- Call summaries
Premium includes those features and unlocks a dedicated OsmO number, calls answered while your phone is offline, Custom Voice, a custom assistant persona, website links for the assistant's knowledge, enhanced missed-call coverage, and iconic voices.
Current store prices
These prices were checked against the official public store listings on July 28, 2026:
| Storefront | iPhone | Android |

Checked against the official US App Store, India App Store, and Google Play listings. Google Play publishes the combined in-app purchase range; the Android app labels the two choices Basic and Premium. Apple and Google control regional pricing, taxes, eligibility, and any trial or introductory offer. The price shown in your own store's purchase screen is always authoritative.
Costs that aren't on the price tag
The question people actually want answered before subscribing to anything phone-related is what else it might cost them. Two honest answers.
You don't need a second phone number. OsmO runs on your existing number through conditional call forwarding, the standard carrier feature that redirects calls you don't answer. No SIM swap, no porting, no extra line on your bill.
Call forwarding itself is usually free — but check your plan. On most major US and Canadian carriers, a forwarded call is treated like a normal call and doesn't add a separate charge. Some prepaid and older legacy plans do meter forwarded minutes. If you're on limited minutes or prepaid, look at your plan's terms for conditional call forwarding before you rely on it. This is a carrier question, not an OsmO one, and we'd rather you check than be surprised.

How to cancel
Your subscription is billed by Apple or Google, not by OsmO directly, so cancellation happens in your store account rather than in our app.
On iPhone: Settings → tap your name → Subscriptions → OsmO → Cancel Subscription.
On Android: Google Play Store → your profile icon → Payments and subscriptions → Subscriptions → OsmO → Cancel.
Cancelling stops the next renewal; you keep access until the end of the period you've already paid for. Refunds are handled by Apple and Google under their own policies, since they process the payment.
One thing worth doing on your way out: turn off call forwarding on your phone. If you leave it on after you stop using OsmO, unanswered calls will keep being forwarded. Our support page covers the codes.
How that compares
For context, the paid tiers of the apps people usually weigh OsmO against:
| App | Paid tier | What it does |
|---|---|---|
| OsmO | Store-localized; plans vary by platform | Screens calls and makes calls for you |
| RoboKiller | from US$4.99/mo | Blocks and answers spam with pre-recorded bots |
| Hiya Premium | from US$2.99/mo | Caller ID, spam warnings, auto-blocking |
| Truecaller Premium | from US$3.49/mo | Caller ID, ad-free, spam database |
| Apple iOS 26 Call Screening | Free | Built-in screening on modern iPhones |
Competitor prices are as listed publicly at the time of writing and change without notice — check their own pages before deciding. The more useful distinction isn't the couple of dollars between them: the caller-ID and blocker apps listed here focus on inbound protection. OsmO also places calls on your behalf, which is where a lot of the time actually goes.
And if your needs are genuinely just "stop obvious spam on my iPhone," Apple's built-in Call Screening is free and decent. We'd rather say that than pretend otherwise.
