Contradict
Read full descriptionHide full description
Why would you want an app that disagrees with you all the time? Good question. Being disagreed with is definitely not a pleasant feeling. But I firmly believe that challenging our own views is a great way to keep our minds open and get closer to the truth. With that in mind, the Contradict app is designed to make disagreement as good as possible. For example, all contradictions will have Wikipedia links, so you can dive into a topic with just a tap.
D2D Tracker

D2D Tracker is the fastest way to count your knocks, conversations, appointments, or sales - whatever you want. Built for door-to-door reps who need a tally counter that keeps up. TRACK WHAT MATTERS Doors, conversations, appointments, and sales - or make it yours. Add your own metrics, pick their colors, and drag to reorder. Hold any card to rename it, fix a miscount, or archive it (your history stays). KNOW YOUR NUMBERS Set your season, build your pay scale, and watch your revenue add up as you close. See where you're pacing and what you're projected to finish the season at - so payday is never a guess. RUN WITH YOUR CREW Follow the reps you knock with and get a live feed of their day - sales as they close, cars as they win them. Check anyone's profile and garage. Turn on alerts and know the second your crew closes a deal. SEE YOUR HISTORY Daily totals with a per-category breakdown, so you know exactly how your week went - doors to conversations to sales. Open the calendar to view or edit any past day. BRING YOUR DATA Switching from a basic tally counter? Import your history and pick up right where you left off. BUILT FOR THE DOORS Works fully offline - no signal at the door, no problem. Light and dark, matched to your phone. Free account gets you backup, sync across devices, and your crew. For solar, pest control, alarms, roofing, fiber, and every crew that knocks doors for a living.

Verdict
The clearest difference is update cadence: D2D Tracker at every 2 weeks against Contradict's every 6 months. Contradict's advantage is iOS requirement (13.0 vs 16.4). On price, ads, in-app purchases and device support there is nothing between them.
