Guess Who: Riddle Me This

The tidbit about 360 being in the 359th position of Pi is amazing.

I enjoy that they make each lesson interactive and visual. I’m able to retain the information easier

Unable to do anything without a subscription. The popups are absurd. Deleted within 2 minutes.

Todas las app ahora es pagar y pagar, ofrezcan productos excelentes que el voz a voz es muy poderoso, cuando ya uno esté motivado decide pagar no al empezar , 6 días free es poco

Could be up front about not being a free app instead of asking 100 questions and then mentioning free trial for 7 days only. During installation also mentions in app purchases rather than a fully paid app

No puedo borrar mi cuenta, es de paga, solo en inglés, interfaz mala… parece un beta, no está lista para los usuarios

Was interested in the idea of this app until you finish the (lengthy) setup process only to be prompted to subscribe to a yearly subscription for $90. What a waste of time and a good concept, be upfront about it being a paid app.

This app is not only substandard and a waste of your time, but the business practices behind it are downright unethical. Unlike nearly every other iPhone app, Nibble doesn’t manage subscriptions through the App Store. Instead, they bury in their fine print that renewals are handled on their website, making the process deliberately murky and confusing. Here’s how it works: you assume, like any rational person, that you can manage your subscription through your phone. You check your subscriptions, cancel trials, and think you’re done. But Nibble hides your subscription status where you’d never find it, and when the renewal comes around—bam! You’re charged $25 for an app you haven’t touched in months and thought you’d canceled. When you contact customer service, they smugly point to their fine print and essentially say, “Too bad—you agreed to this.” This isn’t just bad design or oversight; it’s sneaky, calculated, and despicable. If you value your time, money, and principles, steer clear of this app and its deceptive developers. It’s a trap.

I feel like the app has a lot of potential but it needs more development. The lesson are quick to read through and relatively simple so that you don’t get bored, but I felt like I was bored with this because it was telling me material already know. It didn’t go in to details. It discussed a few main points and moved on to another topic. I feel like your not fully learning the material. You get the basics of what happened or theories and then you move on to another topic. There is no depth to the material; furthermore, the subscription is a bit expensive. I wish there was more depth and a way to quiz your knowledge on certain topics to determine if reading is value added or if simple repetition. The app felt like a waste of time, but I see what the app can become and I hope they add depth, knowledge detection so you only learn what is needed, and cheaper subscriptions.

The lesson was easy to follow. The diagrams gave a clear visual of the concept and the review helped to remember what I learned.
