S1 FinFit is a financial digital assistant available to you free through an invitation from Synergy One Lending. We’re here to help you achieve your financial wellness goals. Organize in one place: Your S1 FinFit dashboard summarizes important financial information such as: account balances, transactions, net worth, budgeting, credit score, cash flow analysis, estimated home value, spending analysis, offers and promotions from Synergy One Lending, and an information center with personal finance articles and videos, all in one place. Budgeting: Understand what you are spending and where. Track your spending by categories and drill down into subcategories. Receive alerts if you are off track or confirmation if you are on track. Free Credit Score, Report and Monitoring: Your credit score is prominently displayed in your dashboard - and it doesn't cost you anything. Track changes month to month and learn the key factors that make up your score like length of credit, timely payment history, utilization of credit, total accounts opened and inquiries. Don't worry, this is a "soft credit pull," meaning there is no impact to your score by checking it. Look through your credit report for accuracy. Access helpful articles that explain credit bureaus, credit score, and more. Prepare: Prepare for home ownership by planning for a down payment, establishing reserves, managing your debt-to-income ratio, improving or maintaining your credit, creating loan scenarios through our calculators, establishing your projected loan-to-value, and more. Visit the readiness assessment in your app to see a snapshot of your credit overview, debt-to-income ratio, cash reserves, employment, down payment, and sales price. Share: When you are ready to move forward with a financial transaction, you choose to share information from your accounts to easily get the process started. All data is always encrypted.

Verdict
The clearest difference is monetization model: S1 FinFit at free against Essential CU's free with in-app purchases. S1 FinFit also leads on update cadence (every 5 weeks vs every 3 months) and iOS requirement (15.0 vs 17.0). Essential CU's advantage is ratings volume (4.6K vs 16) and rating (4.8 vs 4.5). On price, ads, in-app purchases and device support there is nothing between them.
