Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.

About Fermi: Daily Guessing Game
Fermi is a daily game about getting close.
Every morning you get three questions nobody can answer off the top of their head. How many baguettes do the bakeries of Paris sell before noon? How many trees are standing on Earth right now? You don't look it up. You break the problem into pieces you already know, follow a hunch, and put a number on it.
Then you find out how close you landed.
HOW IT WORKS
• Three questions. About three minutes.
• One number per question — no multiple choice, no second tries.
• Your score is the multiple between your answer and the truth. 1x is spot on. Lower is better.
• See where your number sits against everyone else who played today.
WHY IT'S DIFFERENT
Most quiz apps reward what you already memorised. This one rewards how you think. The physicist Enrico Fermi was famous for landing within an order of magnitude of almost anything using nothing but reasoning — how many piano tuners work in Chicago, how much energy a blast released judging by how far the paper scraps flew. That is the skill this app trains, and it gets sharper the more you use it.
WHAT YOU GET
• A fresh set of three questions every morning
• A daily leaderboard, plus weekly and monthly standings
• Your personal best and a running history of every round
• An archive of past days, open whenever you want another round
• The sources behind every answer, so you can see where the number came from
• Metric or imperial units, your choice
No sign-up, no email address, no ads in the middle of a question. Your first round is free; a subscription unlocks every daily round, the archive and the working behind every answer.
Come back tomorrow. There is always another one.
