Mobills makes it easy to\ncreate budgets, record transactions, and track spending and\nbalances on the go. With more than 8 million downloads, Mobills\nlets users manage over 1.5 million credit cards and tracks\npurchases from more than 300 million companies and counting.\n\n*** ** * ** ***\n\n##### Challenge\n\nWhen the team at Mobills wanted to increase their subscription\nand registration conversion rates, they looked for ways to\nimprove their app. They identified two areas of opportunity: a\nlong, single-page registration form and a potentially unclear\nCTA.\n\nTo see if spreading out the registration form over multiple\nscreens would increase conversions, they built a new version to\ntest against the original. They also tested the original\nsubscription CTA, \"Assinar agora\" (\"Subscribe now\"), against a\nnew version, \"Seja premium\" (\"Become premium\"). \n\n*** ** * ** ***\n\n##### Solution\n\nUsing [Firebase A/B Testing](/products/ab-testing)\nand [Remote Config](/products/remote-config),\nthe Mobills team was able to roll out the experiment to a\nsmall set of users without republishing their app. Remote\nConfig allowed them to update the CTA and UI variants\ndynamically, while A/B Testing gave them timely insights into\nthe results.\n\nThe experiments were a success. The new, multi-step\nregistration form led to a 2% higher conversion rate than the\noriginal, while the new CTA increased subscriptions by a\nwhopping 15%. \nAfter sharing the results with the rest of the company,\nMobills now empowers each staff member to run their own A/B\ntests. Recently, they successfully used A/B testing to\noptimize their checkout UI. Using Firebase, Mobills says they\ncan find solutions faster and keep improving their app's\nperformance.\n\n*** ** * ** ***\n\nResults\n\n15% increase in subscriptions\n\n2% increase in registrations \n\n\"Firebase has empowered our entire team to be more creative, because now we have a way to confidently and safely test our big ideas. It makes testing so easy that anyone on the team can run their own experiments.\"\n\n\n- Igor Ronner, Head of Product, Mobills \nTry Firebase today\n\n\nIntegrating it into your app is easy.\n[Get started](https://console.firebase.google.com/) \n\n#### All Firebase products\n\n##### Build\n\n- [App Check](/products/app-check)\n- [App Hosting](/products/app-hosting)\n- [Authentication](/products/auth)\n- [Cloud Functions](/products/functions)\n- [Cloud Storage](/products/storage)\n- [Data Connect](/products/data-connect)\n- [Extensions](/products/extensions)\n- [Firestore](/products/firestore)\n- [Firebase ML](/products/ml)\n- [Genkit](https://genkit.dev/)\n- [Hosting](/products/hosting)\n- [Realtime Database](/products/realtime-database)\n- [Firebase AI Logic client SDKs](/products/firebase-ai-logic)\n\n[Generative AI](/products/generative-ai) \n\n##### Run\n\n- [A/B Testing](/products/ab-testing)\n- [App Distribution](/products/app-distribution)\n- [Cloud Messaging](/products/cloud-messaging)\n- [Crashlytics](/products/crashlytics)\n- [Google Analytics](/products/analytics)\n- [In-App Messaging](/products/in-app-messaging)\n- [Performance Monitoring](/products/performance)\n- [Remote Config](/products/remote-config)\n- [Test Lab](/products/test-lab)"]]
