App idea scorecard

Answer eight questions about demand, money, competition and effort, and get a score for your app idea with its weakest spots and what to do about each. Free, no sign-up.

  1. 01Is there a phrase people would type into the store search for it?
  2. 02How many ratings does the most-reviewed app for that phrase have?
  3. 03Do the leading apps charge (subscription or paid unlock)?
  4. 04How often would someone use it?
  5. 05Have some leaders gone 9+ months without an update?
  6. 06Do low-star reviews repeat the same complaint across apps?
  7. 07Did any app launched in the last 18 months reach the top ten?
  8. 08Does it need new content, moderation or support every week?
Any of these true?

Answer all eight to see the score. 0 of 8 done.

How it works

  • Eight questions, each from a check you can run in the stores yourself: is there a search phrase, do the leaders have ratings, do they charge, have they gone quiet, what do reviews complain about.
  • Demand and money weigh the most, because an idea without them fails whatever else is true.
  • A brand name or a licensed business caps the score: those are dead ends however good the numbers look.

Questions

What score is good?
70 or more is strong. 45–70 is worth a closer look, usually at the weakest spot listed. Under 45, the idea needs a different angle.
Can I trust my own answers?
Only if you looked. Each question tells you what to check; ten minutes in the store beats a guess.
