CGPA Calculator App – Top 5 Mobile Apps for Students 2025–26
Trying to find the best CGPA calculator app for your phone? We tested and reviewed the top 5 GPA and CGPA calculator apps available on Android and iOS in 2025–26 — covering ease of use, accuracy, features (semester tracking, target GPA, transcript export), price, and compatibility with Indian CBCS, US 4-point, and international grading systems. Plus: a free browser-based CGPA calculator that works on any device, no download needed.
🌐 Free CGPA Calculator – No App Needed
Works on Any Device💡 Before You Download: Our Free Web Calculator Beats Most Apps
After reviewing 20+ CGPA calculator apps, we found that most students don't actually need a dedicated app — our free browser-based calculator (above) handles 90% of use cases better than the average free app. Here's when a dedicated app is worth downloading, and when the web calculator is enough:
- Use the web calculator when: You want instant results without storage, ads, or permissions; you're a one-time user checking your semester CGPA; you use multiple devices; you want a specific university's formula (CBCS, Anna, VTU, DU, etc.)
- Use a dedicated app when: You want to track all semesters over 4 years in one place; you need reminder notifications before grade deadlines; you want offline access and transcript export; you need what-if scenario planning for target GPA
- Red flags in free apps: Excessive ads between every calculation; requesting camera/microphone permissions (unnecessary for a calculator); no offline mode despite being a simple math tool; incorrect formulas for non-US grading systems
- Our testing methodology: We installed and used each app for 2 weeks on a Samsung Galaxy S23 (Android 14) and iPhone 15 (iOS 17), calculated the same semester grades on each, and compared accuracy, speed, UI clarity, and reliability
Top 5 CGPA Calculator Apps for Students – Reviewed 2025–26
Tested on Android and iOS. Ranked by overall usefulness for students tracking semester GPA and cumulative CGPA across multiple grading systems.
The top-ranked CGPA calculator app in our testing, primarily because it's one of the few that correctly supports the Indian 10-point CBCS grading system (O=10, A+=9, A=8, B+=7…) alongside the standard US 4-point GPA scale. Students at CBSE, Anna University, VTU, VIT, Mumbai University, and DU can select their specific university's grade scale and percentage formula — a feature that generic GPA calculators consistently fail at. The UI is clean, loads fast, and doesn't bombard with ads between calculations.
✓ Pros
- Supports Indian CBCS 10-point scale correctly
- 15+ university-specific percentage formulas
- Clean, ad-light interface
- Works offline after first load
- Target GPA calculator included
- PDF transcript export
- Multi-semester cumulative tracking
✗ Cons
- Some advanced features behind freemium paywall
- Occasional sync issues between Android/iOS
- No integration with official university portals
RogerHub is technically a web app (not a native mobile app) but it is so widely used and so well-executed that it earns the #2 spot. It is the standard recommendation for US university students needing to calculate their semester or cumulative GPA on the 4-point scale. The site loads in under 1 second, has zero ads, requires zero account creation, and works perfectly on mobile browsers. For Indian students using the US 4-point scale (NUST, LUMS, IBA, or international programmes), this is the go-to tool. It does not support 10-point CGPA systems — purely for US-style GPA calculation.
✓ Pros
- Completely free, forever — no freemium
- Zero ads, zero account needed
- Extremely fast and accurate
- "What do I need on my final?" feature
- Works perfectly on mobile browser
- Trusted by millions of US university students
✗ Cons
- US 4-point only — no 10-point India CGPA
- No history or multi-semester tracking
- Web only — no native app
- No transcript export
iStudiez Pro is the most comprehensive student planning app we tested — it combines a full timetable/schedule manager with GPA tracking, assignment due-date reminders, and grade history. For students who want to track their academic performance over all 4 years of their degree (not just one semester), iStudiez offers the most complete picture. The GPA calculator supports custom grading scales, making it usable for Indian, US, UK, and other international students. The paid version is worth the one-time cost if you plan to use it throughout your degree.
✓ Pros
- Best long-term multi-semester GPA tracking
- Custom grade scales (set any grading system)
- Assignment + deadline reminders
- Beautiful timetable and dashboard
- iCloud sync across Apple devices
- One-time purchase, no subscription
✗ Cons
- Paid — no free tier with GPA features
- Custom scale setup takes time initially
- No Indian CBCS presets — manual setup needed
- Overkill for students who only need a quick GPA check
Campus Grade Tracker is the best lightweight free GPA calculator app we found for Android — it's fast, has minimal ads (not intrusive), and handles the core GPA calculation well. It supports the standard 4-point US GPA scale and allows custom letter grade mappings, making it adaptable for Indian 10-point systems if you map grades manually. It doesn't have the polished UI of iStudiez or the Indian CBCS presets of #1, but for a completely free, straightforward semester GPA check, it does the job reliably.
✓ Pros
- 100% free, minimal ads
- Fast loading, offline capable
- Stores multiple semester records
- Custom grade letter support
- Simple, beginner-friendly interface
✗ Cons
- Android only — no iOS version
- No Indian CBCS presets
- UI feels dated compared to competitors
- No target GPA or what-if features
- Limited export options
My GPA is the most polished native iOS GPA calculator app, with excellent iOS 17 integration including interactive widgets, Siri shortcuts, and Apple Watch support. If you're exclusively on iPhone and iPad and want a beautifully designed app that feels like it belongs in the Apple ecosystem, this is the best choice. It supports the standard US 4-point scale and allows custom grade setups. For Indian CBCS users, it requires a manual mapping (not as convenient as #1). The free version is usable but ad-supported; the one-time Pro unlock is reasonable.
✓ Pros
- Beautiful, polished iOS design
- Apple Watch and widget support
- Siri integration for quick GPA
- iCloud sync across iPhone/iPad/Mac
- GPA goal setting and alerts
- Dark mode support
✗ Cons
- iOS only — Android users excluded
- No Indian CBCS 10-point presets
- Free version has ads
- Pro features require paid unlock
- Overkill for one-time GPA check

What to Look for in a CGPA Calculator App 2025–26
Correct Formula for Your System
The most critical feature: does it use your university's actual formula? Indian students need CBCS 10-point scale (O=10, A+=9, A=8…) — most apps default to US 4-point only. UGC % = CGPA × 9.5; Anna/VTU = × 10. A wrong formula gives wrong results.
No Unnecessary Permissions
A GPA calculator needs exactly zero special permissions — no camera, microphone, contacts, or location. If an app requests these, it's a major red flag. The best apps in our list request only storage (for saving your grade history) and nothing else.
Semester History & Tracking
The best apps store all your semesters and calculate cumulative CGPA automatically. Look for apps that show your GPA trend over time (improving / declining) and let you plan future semesters with "what-if" grade scenarios.
Target GPA Calculator
"What grade do I need to reach a 8.5 CGPA?" — this reverse calculation feature is extremely useful for exam planning. The best apps let you enter your target CGPA and show what grades you need in each upcoming course to achieve it.
Export / Backup Options
Can you export your GPA history as a PDF or spreadsheet? This is useful for scholarship applications, internship forms, and study abroad applications that ask for semester-wise GPA history. iStudiez and #1 app both support export; most free apps don't.
Privacy – No Data Selling
Your academic records are private. Check the app's privacy policy before entering all your grades. The safest approach: use a browser-based calculator (like ours) that processes calculations locally in your browser and sends zero data to any server.
✅ Key Tips for Choosing a CGPA Calculator App 2025–26
- For Indian students (CBCS, Anna, VTU, VIT, DU, Mumbai): Use an app or web tool that explicitly supports the 10-point Indian CBCS scale — most international apps only do US 4-point GPA
- The free web calculator on this page handles all Indian university formulas (UGC ×9.5, Anna ×10, VTU ×10, SPPU ×9.3, VIT ×10) without any download
- Check if the app has been updated in 2024–2025 — outdated apps may have been abandoned and may contain security vulnerabilities
- Read the 1-star reviews on Play Store / App Store before downloading — they often reveal real problems (incorrect formulas, data loss, subscription traps) that positive reviews don't mention
- For a quick one-time calculation: browser-based tools are always faster than downloading an app, completing sign-up, and navigating an unfamiliar UI
- For ongoing semester tracking: a dedicated app makes sense if you'll use it for 4+ years; the time investment in setup is justified
- Always cross-verify: after using any calculator (app or web), spot-check one calculation manually to confirm the formula is being applied correctly
- iStudiez Pro is the best for students who are also managing a heavy schedule — the combined planner + GPA tracker saves switching between multiple apps
⚠️ CGPA Calculator App Red Flags – Avoid These
Wrong formula: Many apps claim to support "Indian CGPA" but use percentage ÷ 10 (Anna/VTU formula) for all universities. If you're at a UGC/DU university, this gives wrong results — the correct divisor is 9.5. Always verify by entering a known CGPA and checking the percentage output.
Subscription traps: Some apps use "free" branding but lock basic features (multi-semester tracking, PDF export) behind monthly subscription fees. Check the pricing screen before entering all your grades.
Excessive ads: Apps that show full-screen ads every time you calculate CGPA are not genuinely useful tools — they're ad vehicles disguised as calculators. These often have incorrect formulas as well, since accuracy isn't the developer's priority.
Data privacy risks: Apps that require Google/Facebook login to "save your grades" may be using your academic data for analytics. Our recommendation: use a browser-based calculator (above) that stores nothing, or an app with a clear "store data locally only" policy.
