Yapp

What the product is

Yapp is a no-code mobile app builder aimed at professional events. The company calls it "The No-Code App Builder for Professional Events" and says you can create iOS and Android apps "in minutes, not months" with no developers or designers. It is written for the person who runs a conference, a sales kickoff, a training day or a trade show and needs an attendee app without a project team behind it. Yapp, Inc. is the company name on the site, and the pages do not say where it is based.

The product has one job and sticks to it: a branded event app that holds the schedule, the speakers, the sponsors, the maps and the files, and that attendees install on their phones. The site also pitches the same tool for employee communications, internal events and sales teams, which are the same app pointed at a company audience instead of a paying crowd.

What you build and how

You build in your browser. The home page describes a drag-and-drop builder "like PowerPoint": you choose a template, drop in your schedule, speakers and sponsors, and preview on real devices before you publish. The company puts the first launch at 30 minutes or less and states that the average time from signup to live app is 31 minutes. The landing page says the app can serve in-person, virtual or hybrid events.

The content layer is the center of the product. Per the home page, an app carries a full agenda, speaker bios, sponsor info, venue maps, downloadable documents, photos and a social feed. The event-app landing page adds rich session details, live polling and Q&A, and slides, abstracts and files, plus an in-app social feed where attendees post photos, videos and comments. Multi-track schedules, speaker directories and a sponsor showcase are named for annual conferences.

Publishing works differently from most app builders, and it is the most useful thing to understand before you buy. Yapp uses what its landing page calls a "single container app." Attendees download Yapp from the App Store or Google Play, and your event content appears inside it. The page says this means no custom build and no waiting on app store approvals: you click Publish and the content is live. It lists iOS, Android and web as the places the app works, and says you "create in your browser" and publish to all three with one click. Updating is just as quick. The company says any content can change in 30 seconds, and attendees see edits without downloading anything new, even during the event.

Attendees get what the home page calls a native mobile experience, and it works offline. Once an attendee has the app, the essential event information is available without an internet connection, which matters in a convention hall with poor reception. Push notifications are part of the app, and the landing page says they are unlimited.

Measurement is built in. The landing page says organizers can see installs, device mix and page views, send targeted push alerts, and watch which features are being used and what is being discussed, then change the event based on it. Sponsors are treated as a revenue line: the page describes premium placements and branded spots inside the app for sponsors and partners.

Anything outside the event shape is not what Yapp sells. The pages describe no database you design yourself, no automation or workflow editor, no API and no code export. If you want a general mobile app for a product or a marketplace, this is a different category of tool. The pages do state one thing that touches the "mobile apps" question directly: you never submit the app to the stores yourself, because the company handles the App Store and Google Play side ("We handle App Store & Google Play").

What the pages say about plans, limits and support

Price is the headline. The home page shows "Yapp $399-799" and says plans start at "just $399 per year," billed annually. Beside that range the company prints its own comparison of what it calls professional event apps: "Cvent $15K-30K," "Whova $8K-12K" and "Bizzabo $10K-25K." A customer testimonial on the page reads: "We were quoted $22K from Cvent and $18K from Whova. Built our app on Yapp in 45 minutes for $450." (Michael Torres, Corporate Event Manager). Those competitor figures are Yapp's own marketing claims, not independent quotes. The company also says its approach cuts event tech costs "by up to 85%" and that it is "up to 90% less than comparable tools."

The pages name what a plan includes: "All features included. No hidden costs. Unlimited attendees." The landing page adds unlimited push notifications and unlimited pages and updates. The pages name no tier-by-tier feature split, so how the $399 to $799 spread maps to differences is not something the site spells out.

Trial and refund terms are stated plainly. There is a 14-day free trial with no credit card required, and a "30-day refund" with "Satisfaction Guaranteed or Your Money back," with cancel-anytime and annual billing noted underneath. After the event, the FAQ says the app stays available for attendees to view content, share photos and network until the annual subscription period ends, and you renew the license for the next event.

On scale, the hero says "Trusted by 350,000+ Events" and "Trusted by 10,000+ organizations worldwide," while a later section says "Trusted by 50,000+ Events." The two event counts disagree on the same page, so treat them as marketing claims. Review ratings are shown as "4.8/5 157 reviews on G2" and "4.7/5 176 reviews on Capterra." The FAQ also says many customers "have stayed with us for over a decade."

Support is a selling point. The home page promises "Real human support during your event hours (not a chatbot)," and the landing page lists "Around-the-clock customer service" and a 100% satisfaction guarantee. Those two descriptions of availability are not identical, so check the hours before a high-stakes event.

The pages publish no security certifications, no compliance claims, no integration list and no open-source license.

Who it suits and who it does not

Yapp suits an event organizer on a small budget and a short clock. The home page names annual conferences of 100 to 10,000 attendees, medical associations, trade shows and professional societies, plus corporate events such as sales kickoffs, company meetings and team off-sites. One testimonial comes from a board member of a small association who said the team "were worried about how much time it would take to set up our conference" and that the group had printed a conference booklet before switching to the mobile platform. A conference that runs every year can reuse and update the same app.

It also fits an operations or communications team that wants an internal app for meetings and trainings. The site lists employee communications, internal event apps and sales team apps as use cases.

It does not fit a founder building a product app, a store or a service-booking tool, because the whole offer is shaped around schedules, speakers, sponsors and attendee engagement. It also gives you no code layer: if you need custom logic, an API or an escape hatch into code, the pages offer none. And because attendees open your event inside the Yapp container app, the app lives in the Yapp ecosystem rather than as a separately branded listing in the stores. For a team that needs its own app store presence, that is a real trade-off against the speed it buys you.
