Does a smartphone always replace a radioguide?

Not always. Phones can reduce receiver handouts but bring different batteries, settings and support needs. Receivers let you check every device before departure. Compare both with the same audience and route.

Is using visitor phones free?

No. Include service or development, support, signage, testing, network and alternatives. Compare total cost, not only hardware.

Is phone-based capacity unlimited?

No. Hotspot, model, application and environment have limits. Valid capacity is what you demonstrate with real equipment and route.

Does an external Wi-Fi router raise capacity compared with a phone hotspot?

It changes the equipment creating the network but does not establish capacity for more listeners. Test audio and recovery with your group, and check that phones can communicate. The router connection limit is not a tested group capacity.

What is a hybrid model?

Visitor phones as the main option with compatible loan phones for those who need them. A traditional radio receiver does not automatically receive Wi-Fi audio; it would need its own compatible system.

How do I compare fairly?

Define the same group and service, add purchase or rental, licences, operation, support, replacement and staff time, then test each option on the route.

How can I try Echoris before a tour?

Prepare two compatible phones with Echoris and earphones: one acts as the guide and the other as a visitor. Check joining, listening and reconnection. Then extend the test to your intended route and group; two phones do not establish capacity for a full tour.

Tour guide systems vs smartphones: costs compared

A dedicated tour guide system and a visitor’s phone can both deliver the guide’s voice through earphones. The difference is in the equipment you prepare, the support the group needs and the cost of running the visit. The right choice for your business depends on those tasks as well as the listening experience.

Which option fits your group?

Owned or rented receivers: you can charge and check every unit before the visit. Consider them when you need visitors to use familiar equipment, especially if they do not carry phones or prefer not to use them.
Visitor phones: you can reduce equipment handouts when the group brings compatible phones and earphones. You will need to prepare the connection and help anyone who needs it.
A combined model: visitors use their own phones, with compatible loan phones running the same app available as an alternative. This avoids requiring everyone to bring a phone.

Echoris fits the phone option: it is an audio guide system that runs on phones, where the guide speaks through theirs and visitors listen on their own. The two-phone trial at the end helps you get familiar with that process before deciding.

Compare the same visit

Write down your group size, monthly departures, tour duration and route. Include languages and access needs. Compare both systems under those same conditions.

For dedicated systems, count transmitters, receivers, earphones, chargers and transport. For phones, include the app, network and any loan devices needed. If some visitors cannot listen, add an alternative before comparing the cost.

Costs: what to include for each option

Add up twelve full months:

Annual cost = purchased or rented equipment + licences or service + transport and replacements + preparation, cleaning and support work.

Divide by the tours you actually expect, including the low season. Count each expense once: if preparation time is already included, do not add those hours again as staffing.

Using visitor phones does not remove every cost: there may be service fees, network equipment, loan phones, support and testing. Dedicated receivers also take time to hand out, count and troubleshoot. Include signs and instructions if needed.

For example, if you run several departures in a day, count preparation and collection for each one. With phones, record how much help the group needs to get started. Use your own timings and quotes rather than assuming a percentage saving.

Equipment and batteries: what you can prepare in advance

Preparation before the group arrives
Equipment	What to prepare
Owned or rented receivers	Charge, channel, volume, enough units and spares.
Visitor phones	Explain the app, earphones and battery requirements. Plan help for different models and settings.
Loan phones	Charging, handing out and collecting also belong in the plan.

If several groups use radio receivers at once, test that their channels do not interfere. With visitor phones, allow for different battery levels.

Connection: what changes with Echoris

Echoris audio travels over a local Wi-Fi network created by the guide phone or an external router. Once the network exists, audio does not need internet access. Enabling the phone hotspot can depend on the model, carrier and plan.

A router adds equipment to carry, charge and configure. Check that it allows phones to communicate: some isolation settings and guest networks block this. Its advertised connection limit is not a tested listener capacity.

The guide linked below covers setup step by step. When choosing between models, focus on this check: joining, audio and recovery must work with your equipment, route and intended group.

On real tours of about 20 people we use the TP-Link M7450 V3, a pocket router with its own battery. We use it without a SIM to create the local network. That experience does not certify capacity on another route. What we carry ourselves is in the kit for a live tour.

Handing out or connecting: time the start and the end

Time it from the moment the group arrives until everyone can hear. With receivers: hand out, adjust and swap the unit that stays silent. With phones: open the app, connect and help whoever gets stuck. At the end, receivers need collecting and counting; visitor phones do not, but loan phones do.

Accessibility and privacy: prepare alternatives

Ask what each visitor needs to listen comfortably. Check volume, personal earphones and, where relevant, hearing aids, implants or compatible neckloops. You do not need to ask for a diagnosis to offer options.

Prepare an alternative for anyone who needs text or other support. W3C calls for an equivalent text alternative to prerecorded audio. For live commentary, decide how to make the essential information accessible. The guide for hearing-aid users details checks and alternatives.

If you use an app, explain the permissions and data it requests and why. Make that information clear before visitors decide whether to use it.

Test it where it will be used

With receivers, check interference, range at the worst point and how to replace a unit. With phones, check joining, guide and visitor battery life, and what happens when reconnecting.

Run the test while walking, with real background noise and at the group size you need. Two phones working together are a first step; they do not establish capacity for a whole departure.

Have a concrete fallback: stop, regroup, give essential information or split the tour. Audio does not replace headcounts or override local group-size limits.

How to decide

Consider what you can maintain over a full day. If controlling every device is the priority, start by testing receivers. If your audience is willing to use their phones and you want fewer equipment handouts, try that option and measure the support it needs.

If you need loan equipment, include its cost and preparation. Conventional radio receivers do not automatically receive an app’s Wi-Fi audio: use compatible phones or a complete, separate radio system.

For comparable quotes, use the tour guide system selection checklist.

Try Echoris with two phones

Prepare two compatible phones with Echoris and a pair of earphones. Use one as the guide and the other as a visitor. Listen to some commentary, walk and check how the connection recovers if interrupted.

This lets you assess how it works before arranging a trial with your actual group. Then record preparation time, help needed and any failures, just as you would with receivers.

Prepare an Echoris trial with two phones.
