The absolute best app for SOF IMO (International Mathematics Olympiad) is the official SOF Olympiad Trainer and Gonit is excellent for advanced problem-solving practice.
Finding the Best apps for SOF IMO preparation can be confusing. Some apps closely follow the exam pattern, while others focus on building broader problem-solving skills.
To help parents and students choose wisely, we evaluated six popular SOF IMO preparation apps based on syllabus coverage, mock tests, previous-year papers, pricing, features, and user feedback.
This guide highlights what each app does well, where it falls short, and who it is best suited for.
How We Evaluated These Apps
Every app in this list was assessed against the following criteria:
- SOF IMO syllabus alignment: Does the content actually match what’s tested?
- Mock test quality and quantity: Are the mock tests genuinely exam-like, or just random MCQs?
- Previous-year paper availability: A key differentiator for serious preparation.
- Class-wise support: Does it work for your child’s specific grade?
- Question difficulty vs real exam: Are questions too easy, too hard, or well-calibrated?
- Progress tracking and analytics: Can you identify weak areas meaningfully?
- Free vs paid features: Is the free tier actually useful, or just a teaser?
- Update frequency: Has the app kept up with the 2025–26 exam pattern?
- User feedback: What are students and parents actually saying?
Overview of SOF IMO Preparation Needs in 2026
The SOF International Mathematics Olympiad (IMO) is one of India’s most widely participated school-level math competitions, open to students in Classes 1 through 12.
The exam tests mathematical reasoning, problem-solving, and logical thinking, not just syllabus memorisation.
It follows a structured pattern with sections covering mathematical content, everyday mathematics, and an achievers section for higher-order thinking.
For 2026, the exam continues to be conducted at two levels: Level 1 (school-based) and Level 2 (for top scorers).
The achievers section, in particular, has become more challenging over recent years, and many students underestimate it until they sit a proper mock test.
A good prep app for the SOF IMO needs to do three things well: cover the class-specific syllabus accurately, provide realistic mock tests that mirror the actual exam’s difficulty, and help students track where they’re struggling.
Apps that do only one or two of these things are useful but incomplete. You can learn more about the full SOF IMO exam pattern and syllabus before choosing your app.

Which App is Best For You?
Best App Overall
SOF Olympiad Trainer for students whose primary target is the SOF IMO, especially Classes 5–10. The content is the most directly aligned with the actual exam.
Best Free App
Gonit App offers the most genuinely useful free experience for daily math practice. For free SOF-specific content, Olympiad Success has the most accessible free worksheets.
Best for Beginners (Classes 1–4)
Practido wins here — its visual design, gamified elements, and age-appropriate interface make it the most accessible choice for younger children. Gonit App is also excellent for building foundational math confidence at this level.
Best for Middle Classes (Classes 5–8)
SOF Olympiad Trainer or Olympiad Success, depending on whether you prioritise exam alignment (former) or analytical depth and question variety (latter). Using both isn’t overkill for a motivated student.
Best for Advanced Students (Classes 9–10)
SOF Olympiad Trainer for Level 2 preparation specifically. Olympiad Success for broader conceptual strength and performance benchmarking.
Best for Rank-Focused Preparation
If you’re aiming for a top-100 or zonal rank, you need SOF Olympiad Trainer for previous-year papers and Level 2 mock tests, combined with Olympiad Success’s question bank depth.

Best for Mock Tests and Previous-Year Papers
SOF Olympiad Trainer is the clear winner for SOF-specific mock tests. For a wider range of previous-year papers across classes, Olympiad Success is a strong second.
SOF IMO sample papers can also give you a benchmark before you invest in any app.
Are Apps Enough for SOF IMO Preparation?
Honestly for most students at Class 1–7 level, a good app combined with regular school study is sufficient to do well at Level 1.
The SOF IMO at these levels tests curriculum knowledge plus some reasoning, and a focused app covers that well.
For Classes 8–10, and especially for Level 2, apps alone are usually not enough. The achievers section requires deeper problem-solving skills that benefit from exposure to varied question types beyond what any single app provides.
In these cases, supplementing with MTG or Arihant IMO workbooks, or enrolling in SOF Olympiad Trainer’s online concept classes, adds meaningful value.
The honest answer: apps are excellent for building speed, accuracy, and comfort with the exam format. They’re not a substitute for genuine conceptual understanding.
Gonit App specifically is designed to build that underlying mathematical thinking which is why it works well as a daily companion rather than a last-minute cramming tool.
For students asking whether apps can fully replace other study resources, the short answer is: they help a lot, but the best results come from combining them thoughtfully.
Parent Buying Guide
Here’s what to actually look for when choosing an app for your child:
Match the app to your child’s class. Practido only covers Classes 1–8. If your child is in Class 9, that immediately rules it out. Check class support before downloading anything.
Test the free tier first. Most platforms offer enough free content to judge the question quality and interface. Spend 20–30 minutes with the free version before paying.
Check update dates. An app that hasn’t been updated since 2023 may have syllabus gaps.
Look at the Play Store/App Store update history; regular updates (every few months) indicate an active platform.
Watch for over-promised analytics. “AI-powered personalised learning” is on nearly every app’s listing.
Ask what that actually means: does it adapt question difficulty based on performance, or just show a score graph? The latter is basic, not adaptive.
Budget considerations. SOF Olympiad Trainer starts at ₹1,499 for a one-subject package, which is reasonable for 4–6 months of prep.
Olympiad Success’s test series at ₹999 is also fair value. If budget is a concern, Gonit App’s free tier and Olympiad Success’s free worksheets give meaningful practice at no cost.
Red flags to avoid: Apps that guarantee rank improvements, apps with no update history, or platforms where the “free trial” requires payment details upfront.
Which is the best app for SOF IMO preparation?
For students focused specifically on the SOF IMO, SOF Olympiad Trainer is the most directly aligned option; it most closely matches SOF exam patterns, previous-year papers, and Level 2 content. For students who also want to build genuine depth in problem-solving, pairing it with the Gonit App for daily math practice yields better long-term results.
Is the SOF Olympiad Trainer app free?
SOF Olympiad Trainer has a limited free tier that gives access to some sample papers and trial questions. Most meaningful content full mock tests, complete previous-year papers with solutions, and chapter-wise test banks requires a paid subscription starting from approximately ₹1,499.
Which app is best for Class 5 IMO preparation?
For Class 5, both Practido and SOF Olympiad Trainer are strong choices. Practido is more engaging for students newer to Olympiad prep. SOF Olympiad Trainer goes deeper on exam-specific content. Gonit App is excellent for building the underlying math skills. A combination of Gonit App for regular practice and SOF Olympiad Trainer for mock tests works very well at this level.
Can I prepare for SOF IMO using only an app?
For Classes 1–7 and Level 1 preparation, a good app is likely sufficient for most students. For Classes 8–10 or Level 2, apps should be supplemented with workbooks, and for serious rank aspirants, concept classes. Apps are strongest at building speed and familiarity with the exam format. Check out a detailed guide on how to prepare for the SOF IMO for a full roadmap.
Is Practido good for SOF IMO preparation?
Yes, particularly for Classes 1–8. Practido covers SOF Olympiad patterns, has a clean interface, and is available on both Android and iOS. Its main limitation is the class ceiling of Class 8 students, above whom a different platform is needed. It’s also better for multi-board students than those focused exclusively on SOF.
What features should I look for in an Olympiad prep app?
The essentials: SOF IMO syllabus alignment, previous-year paper access with explained answers, timed mock tests that mirror actual exam difficulty, class-specific content, and a way to track weak topics. Nice-to-haves: adaptive question selection, performance comparison with peers, and hint systems for self-learning. Avoid apps that only offer question banks without any performance analysis, knowing your score is less useful than knowing which chapters to fix.

Conclusion
The best SOF IMO app depends on your child’s goals.
SOF Olympiad Trainer is the strongest choice for exam-specific preparation, while Olympiad Success offers greater question variety and analysis.
