The Solve Finance App is where you can apply for Personal Loans, help build your credit report track record (we offer small Credit Builder loans), and view your credit report to help you better navigate your finances. With no impact to your credit score, you can see amounts, estimated rates, and monthly payments before verifying your income to apply for one of our direct loan programs. Enter your information once and keep up with your progress in the app. Direct Loan programs are offered by Franklin Credit. Any pre-approval for a loan program is based on your credit report and is not a commitment to lend — final terms are determined for completed applications using bank data to give as fair and full underwriting as possible, and try to offer options to as many people as possible. View your credit report and score. Track changes over time, review your accounts and balances on file, and see why your score is what it is and figure out your next move. Pulling your report through the Solve Finance app does not affect your score. HOW IT WORKS Create an account and tell us what you're looking for. View your credit report and see what you pre-qualify for. Complete your application and review rates, terms, fees, and monthly payments. Solve Finance was built by a team with backgrounds in household finance research and software engineering. You choose which products to apply for and when.

Verdict

The call

The clearest difference is monetization model: Debt Optimizer at free with in-app purchases against Envelope Budget's subscription.

On price, rating, ads and in-app purchases there is nothing between them.
