The easiest way to stay healthy

Crumb is a revolutionary fitness mobile application that was supported by Interexy from the very beginning.

The app provides users with rewards within local businesses for various fitness activities, connecting to users’ Health App. This way product motivates the population to be more active and makes the process more fun, personalized & convenient. The fitness & wellness focus of the product along with implementation quality led to multiple successful fundraising activities from the government of Germany by the founders of the app.

Users get rewards within local stores whether these are discounts for protein shakes or sports supplements or beauty products.

Interexy team was chosen as a provider for the company from day 1 assisting the Crumb team to overcome challenges along the way.

introduction

Product Concept

Crumb main concept is to make it easier for people worldwide to spend time outside doing sport & fitness activities by providing various rewards, discounts & benefits within local shops & restaurants.

Who would not want to get a free cup of coffee after a good morning walk? That’s the concept Crumb leverages and that’s the vision that stays behind the company – helping users to be more active & local businesses to drive in more potential clients & sales.

Goals & Objectives

Crumb met Interexy team at a very complex point of its lifecycle – they were running late with the first build release having inhouse CTO coming from a web background working on a hybrid cross-platform version of the app – spending too much time & money for Health App integration which was the core feature of the app – resources the team did not have.

We came into the product team & quickly outlined the main issues – the technology that was being used. We decided to focus on the iOS version & use native Swift iOS language to integrate the Health App which only took a couple of days to finish.

We’ve delivered the first version on time within the first 5 weeks & were able to allow Crumb to extend the pre-seed fundraising round & continue working on the product further.

UI & UX design was one of the main reasons for product rapid growth & initial market success – we decided to make it clean, robust & simple to use on the go.

Design Creation

One of the main differentiators in Fitness & Wellness is the UX of the product – many companies develop functional telemedicine apps but they often lack clear & simple UX with sophisticated design in place – that what Interexy’s team focused on during the design process.

Users are able to clearly see each metric of their physical activities & and extended information over each of them. We’ve made sure it’s convenient & also extendable for people specifically focused on data & want to know more.

Design Challenges

The goal of the product was to be being used by the vast majority of the population – for us that meant that we should adjust to quite a different user base & make it convenient for each of them.

We made sure the app is easy to use on the go & has a clear flow in each of its parts to make it more appealing for businesses to be presented on the product.

MVP Fundraising Activities – what happened after first 5 weeks

Crumb met Interexy team at a very complex point of its lifecycle – they were running late with the first build release having inhouse CTO coming from a web background working on a hybrid cross-platform version of the app – spending too much time & money for Health App integration which was the core feature of the app – resources the team did not have.

We came into the product team & quickly outlined the main issues – the technology that was being used. We decided to focus on the iOS version & use native Swift iOS language to integrate the Health App which only took a couple of days to finish.

Development Process

iOS Version Improvement

After the acquire of seed funding we continue with the iOS version build.

Android Version Kickstart

We also kicked off the Android version using native Kotlin development technology following iOS example for best UX & perforamance.

Backend Extension

We started to rewrite the backend to adjust to modern scalability & extendability requirements.

New UX Challenges

With new application features we also have new UX challenges to keep the product simple & easy.

Start of the Android app development

Android app development began with clear planning & overview sessions based on the existing iOS version & demands of the Android target audience – based on our experience we knew that Android users are used to the slightly different user experience from iOS one mainly dictated by different operation system & a range of different user flows as well.

Then we began architecting the Android version & implementing the navigation for the future application flow along with network layers and data models.

We also had time constraints when working on the Android version since investors wanted to see it released fast & we needed to move quickly to meet those requirements – daily calls with the Crumb team were a necessity & we felt like a full-time development team of theirs – the Crumb team even shared some of their branded merch with us 😊

Development technlonogies

We specifically chose native app development languages for the sake of clear & smooth integration with Apple Health Kit & Google Health to show relevant & useful data to app users & allow for peak performance & best user flows.

The goal to disrupt the marketplace with the revolutionary concept but also do it in a sophisticated way by providing a very robust, clean & functional piece of software to be enjoyed by a healthy population in Germany.

Technical Implementation

1. New Social Functionalities

With the extension of iOS version fo the product we put emphasis on social functionalities development – referral system was on of them which lately led to a rapid app growth within the region.

User profile & various social features were also additions into the build.

2. Referral System

We carefully thought through the referral system & added a competitive touch to it as well – fitness-focused audience likes the competition & it drives downloads & new users for the apps based in this niche.

3. Local stores benefits & discounts

Connection of fitness activities within benefits & discounts in local shops, stores & cafes increased the power of the referral system that was in the app and allowed for even faster application growth. By bringing more leads to local businesses we had more & more of them wanting to jump on the service.

4. In-app content & app retention

In-app content was the way for us to establish high retention rates & lower the churn rates on the product – Crumb team was constantly working on adding the new content into the project & making sure it was up-to-date & specific to locals.

User Wallet

We also were engineering & thinking through the fintech-related part of the project with the implementation of in-app currency through the app wallet. We even had projections in the future to extend to blockchain space with our own Crumb tokens & smart contracts to make sure we have a secure & efficient way for transactions between local businesses & customers of the services.

We ended up integrating a convenient & easy to use wallet feature so users of the app can see at any moment how many Crumb tokens they have & what benefits, discounts & products they can get within local businesses for it.

We also were promoting certain businesses in the wallet section based on the interests & preferences of the users gather by the app to make sure we’re providing a relevant & top-notch experience to our audience.

Flawless Login Flows

One of the success reasons for the referral program was login flow with clear onboarding screens that made it very easy for users to understand how to use the app & what’s the value the app brings.

We focused on making it engaging & simple for the users keeping in mind the target audience and goals of the product.

Gamification

Gamification was also a huge part of our product engineering – we wanted to make sure that the app will be engaging, give dopamine hits by reaching certain milestones with fitness & benefit the users for it since fitness activities are something that has a high turn-down rate due to usage of will power and we knew we need to gratify our users for performing them.

We adjusted fitness activities based on the preferences of each user & were providing useful content on how to improve in certain areas benefiting users through the process.

Technical Outcomes

We came into the cross-platform unfinished version with lagging Health flow – we left by having two pixel-perfect gamified native apps with seamless backend integration, referral program & a satisfied and growing user base.

Business Outcomes

The product passed through the harsh COVID-19 period & was able to survive and fundraise further to the continuation of the app development. The app successfully passed 3 funding rounds with Interexy as a development team.

Saad Saeed

Founder & CEO @ Crumb

Within its first nine weeks, the app received 8,000 users and a 4.7-star rating. The platform is well designed and hasn’t had many bugs. Interexy LLC is fast and efficient at building new features as well as taking scope changes in stride. Expertise and responsiveness are hallmarks of their work.

Will von Behr

Founder @ Urbs Travel

I got an amazing product that was exactly what I envisioned when I first sat out & drew the plans. The two areas that I think where Stan & his team particularly excel: first is attention to detail (…) & secondly the kind of support they’ve provided after the app was largely complete. I’m sure the number of teams just do the bug work & leave it but they are [Interexy team] always on hand to answer any questions really at any time of day which is incredible. So I’d encourage anyone who wants to build any sort of product to use Stan & his team. It’ll accelerate your business and make your life a whole lot easier.

Doug Scibilia

Founder & CEO @ SQRK – Squaker

Before choosing Interexy, I’ve hired a firm out of India – they gave me a great price, great timeline (…). And after close to a year, they told me they couldn’t get the project done. Then I started to talk with Stan from Interexy. I hired them, they quoted me 8 weeks to get this project done, well, 8 weeks later – the project is done. Now I just have nothing but a great thing to say about the company – they were on time, great communication and just great people there. I’d 100% recommend Interexy for any web development or app development project that you have out there, they’re just fantastic.
