Your POC radio is only as good as the app running on it. Some radios run any Android PTT app. Others are locked to the manufacturer's platform. And some apps work on your phone without any dedicated radio at all. Here's the full breakdown — which app to use, with which radio, for which use case.
Not every POC radio runs a third-party app. Understanding your device first saves a lot of confusion:
| Radio | App type | Zello | Odmaster | Own platform |
|---|---|---|---|---|
| Inrico T320 | Android-based — runs any app | ✓ | ✓ | ✗ |
| ChoYong WT2 | Proprietary POC network | ✗ | ✗ | ✓ Built-in |
| TIDRADIO TD-M2 Pro | Odmaster app | ✗ | ✓ | ✗ |
| AnySecu 3G-PPT | Android-based — runs any app | ✓ | ✓ | ✗ |
| Hytera PNC360S | Hytera Horizon platform | ✗ | ✗ | ✓ Horizon |
| Motorola WAVE PTX | WAVE PTX platform | ✗ | ✗ | ✓ WAVE PTX |
| Your smartphone | Runs any app | ✓ | ~ | ✗ |
Zello is the default answer when someone asks "what app should I use with my POC radio?" — and for good reason. It has the largest user base of any PTT app, the most mature feature set, and the best community support. The free consumer version covers everything most individuals, hobbyists, and small groups need: unlimited channels, up to 6,000 users per channel, voice history, and hardware PTT button mapping on compatible Android radios.
Zello Work adds live GPS tracking, dispatch console, and admin management for teams — the business tier that turns Zello from a walkie-talkie app into a fleet communication platform.
Odmaster is TIDRadio's proprietary PTT platform — purpose-built for their device lineup. It's not as feature-rich as Zello Work, but it doesn't need to be. Setup is fast, group management is straightforward, and the $9.99/yr subscription after the first free year is the most transparent pricing in the category. For TIDRADIO hardware specifically, Odmaster is the correct and optimized choice.
Voxer sits between a walkie-talkie and a voice messaging app — it supports both live real-time PTT and asynchronous playback (like a voice text message). It's the better choice for casual groups where not everyone is listening at the same moment, and for mixed use cases (voice + photos + location sharing in one thread). The tradeoff: no hardware PTT button mapping, so it works best on smartphones rather than dedicated POC radio hardware.
Hytera Horizon is a dispatch platform, not just an app. The web-based console gives a manager a live map showing every radio's GPS location, with one-click broadcast to the entire fleet or any subgroup. Emergency SOS sends GPS coordinates instantly to dispatch. For businesses managing mobile workers — delivery, security, construction, field service — Horizon's dispatch view is the feature that justifies the per-seat monthly cost.
WAVE PTX is Motorola's enterprise PTT platform — the right choice for organizations already running Motorola LMR systems who want to extend to cellular without rebuilding their communications infrastructure. It bridges LMR and PoC into one platform, with IT-grade user management built for large headcounts. Overkill for small teams, exactly right for enterprise deployments.
ESChat targets government and public safety — it interoperates with P25 LMR networks, carries AES-256 encryption, and is FirstNet certified. It's not the right app for a prepper or small business, but it's the correct choice for municipal or agency deployments that require security compliance and LMR bridging.
| App | Free tier | Paid from | GPS dispatch | Hardware PTT | LMR bridge | Best for |
|---|---|---|---|---|---|---|
| Zello | Yes | ~$6/user/mo | Work tier only | Yes | Via gateway | General use, hobbyists, fleets |
| Odmaster | Yes | $9.99/yr/radio | No | Yes (TIDRADIO) | No | TIDRADIO users |
| Voxer | Yes | $8.33/user/mo | Basic | No | No | Casual / async voice |
| Hytera Horizon | No | ~$15/user/mo | Yes — live map | Yes (Hytera) | No | Fleet dispatch |
| Motorola WAVE PTX | No | ~$25/user/mo | Yes | Yes | Yes | Enterprise / LMR orgs |
| ESChat | No | ~$4.99/user/mo | Yes | Yes | Yes (P25) | Government / public safety |
It depends on the radio. Android-based POC radios like the Inrico T320 can run any PTT app — Zello is the most popular. Dedicated POC radios like the TIDRADIO TD-M2 Pro use Odmaster. Enterprise radios like Hytera use Horizon. Most consumer POC radios are Zello-compatible.
Zello's consumer app is free for personal use with unlimited channels and contacts. Zello Work (business version with dispatch, GPS tracking, and admin console) starts at around $6–8 per user per month. Most hobbyists and preppers use the free version successfully.
Zello Work is the most widely used PTT app for small businesses — proven track record across delivery, security, and construction, with a browser-based dispatch console and live GPS tracking. For businesses already using Hytera hardware, Horizon is better integrated.
No — the ChoYong WT2 has its own built-in POC channel system and does not run the Zello app. For Zello compatibility, Android-based POC radios like the Inrico T320 are the better choice.
