Find out what your phone plan is really costing you
PlanCheck launched on March 24, 2026.
What it does
A free, independent phone plan savings calculator. Enter your bill, pick your phones (new, used, or hand-me-downs), and see a 36-month cost comparison between your carrier and top MVNOs like Visible+ and US Mobile. Receipt-style results show exactly how much you could save — often $1,000-3,000+ for families. No sign-up, no tracking, no affiliate links. Runs entirely in your browser, built to show that MVNOs use the same towers for half the cost.
Enter your monthly phone bill. See how much you could save by buying a phone outright and switching to an MVNO.
How we calculate: Your total monthly bill ÷ lines × 36 months = carrier total. We compare that to buying phones outright + MVNO service for the same period. Monthly savings are also shown for easier budgeting. MVNO pricing: Visible+ includes taxes at $35/line with priority Verizon data. US Mobile Premium includes taxes at $44/line with multi-network choice. US Mobile Starter includes taxes at $25/line. US Mobile Pooled pricing is $10 first line + $8/additional + $2/GB shared data, all taxes included. Used phone estimates: Used/refurbished prices are approximated at ~70% of retail. Actual prices vary by condition, seller, and market. Check Back Market, Swappa, or manufacturer…from costcheck.org

I built a free app for New Yorkers to save money on groceriesJul 2026 · sbnyc.app · ▲13I built this because I see that grocery savings are achievable in NYC. People usually just go to the store they're used to going to, and it's rarely worth the effort of combing through card cashback, weekly coupons, CPG rebates. Most people leave real money on the table by not stacking them, and even more don't even know that these deals are out there.... so I built a way to automate it. You can use it for free, no login, currently NYC-only with ~690 stores. I built it so that you just search whatever you want (use commas if you want to search multiple items). Or - use the AI tool to help…
