The short version

  • Each has a real cost: Duolingo free tier includes ads and energy-based hearts system limiting daily practice without paying; Photomath full free step by step solutions make it straightforward for a student to submit copied working without doing the reasoning themselves, which is a real concern for teachers assigning homework.
  • They diverge on capability: Duolingo covers 40+ languages, Photomath covers Camera scanning.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Duolingo

  • Free tier includes ads and energy-based hearts system limiting daily practice without paying
  • Gamification focus may appeal to casual learners but lacks depth for serious language study beyond conversational basics
  • Limited to short, bite-sized lessons without extensive grammar explanations or cultural context

Photomath

  • Full free step by step solutions make it straightforward for a student to submit copied working without doing the reasoning themselves, which is a real concern for teachers assigning homework.
  • Word problems, a common school assessment format, are gated behind the Plus subscription, so the free tier is weaker on exactly the problem type many students struggle with most.
  • Camera recognition of messy handwriting or complex notation such as matrices or multi-line proofs is unreliable, and misreads produce confidently wrong steps.
  • Since the 2022 Google acquisition, the product sits inside a company whose primary business is advertising and data, which is a relevant factor for schools with strict student data policies.
  • It solves problems rather than teaching underlying concepts from scratch, so a student with no foundational understanding gets a worked answer but not necessarily comprehension.
