The "Free" Trap in Note-Taking Apps
The note-taking app market is booming. According to The Business Research Company's January 2026 report, the market reached $11.02 billion in 2025 and is projected to hit $13.3 billion in 2026, growing at a compound annual rate of 20.6%. With that kind of growth, the competition for your attention — and your data — is fierce. The most common entry point for new users is a free plan. But "free" in this market rarely means costless.
The real price you pay often comes in three forms: proprietary formats that make leaving expensive, sudden price hikes after you have years of notes locked inside, and privacy trade-offs that put your data at risk. This article breaks down the total cost of ownership (TCO) of seven major note-taking apps over a three-year period, factoring in subscription costs, sync fees, migration expenses, and the value of your data sovereignty.
Case Study: Evernote's 86% Price Hike Under Bending Spoons
Evernote is the cautionary tale that every note-taking app user should know. After Bending Spoons acquired the company in 2022, the annual subscription climbed from $69.99 to $129.99 — an 86% increase, as documented in Atlas's April 2026 evaluation. The free plan was gutted to just 50 notes and a single device. Users who had built decade-long archives faced an impossible choice: pay the new price or attempt a painful migration.
This pattern is not unique to Evernote. When a company changes hands or faces pressure to monetize, the free tier is often the first thing to shrink. The risk is highest for users who have accumulated hundreds or thousands of notes in a proprietary format that is difficult to export cleanly.
Free-Tier Restrictions Across 7 Major Apps: What You Actually Get
Free tiers serve two purposes: they let you evaluate a tool, and they build your dependency on it. The restrictions below show how quickly a "free" app can become unusable for serious note-taking.
| App | Free Tier Limits | Paid Plan Starts At | Last Verified |
|---|---|---|---|
| Evernote | 50 notes, 1 device, 250MB/month uploads | $14.99/month (Starter) | May 2026 |
| Notion | Unlimited pages, 7-day page history, 5MB file uploads | $10/user/month (Plus) | May 2026 |
| OneNote | 5GB storage, all core features | $1.99/month for 100GB | May 2026 |
| Apple Notes | 5GB iCloud storage (shared across all services) | $0.99/month for 50GB | May 2026 |
| Obsidian | Unlimited local notes, no cloud sync | $4/month (Sync add-on) | May 2026 |
| Joplin | Unlimited local notes, no cloud sync | €2.99/month (Joplin Cloud) | May 2026 |
| Google Keep | Unlimited notes, 50MB per note | Included with Google Workspace | May 2026 |
The key takeaway: Evernote and Notion impose the most aggressive limits on free users. OneNote and Apple Notes offer generous free storage but tie it to their respective ecosystems. Obsidian and Joplin give you full functionality locally for free — you only pay for optional cloud sync.

The Export Problem: How Easy Is It to Leave?
The single biggest hidden cost of a note-taking app is the difficulty of leaving it. If you cannot export your notes cleanly, you are locked in — and the vendor knows it. The Atlas evaluation framework, published in April 2026, rates apps on a "Data Sovereignty Quotient" that measures how easily you can take your data elsewhere.
| App | Data Sovereignty Score (Atlas) | Export Format | Migration Difficulty |
|---|---|---|---|
| Obsidian | 10/10 | Plain Markdown files | Trivial — files are already on your device |
| Joplin | 10/10 | JEX (JSON-based), Markdown | Easy — open format, multiple export options |
| Notion | 5/10 | Markdown (partial), HTML, PDF | Moderate — formatting loss, database structure issues |
| Apple Notes | 3/10 | ENEX (via export), PDF | Hard — no native bulk export, requires third-party tools |
| Evernote | Not scored separately | ENEX (proprietary XML) | Hard — formatting loss, attachment issues |
| OneNote | Not scored separately | HTML, PDF, Section files | Moderate — notebooks export individually |
Obsidian's approach is the gold standard: every note is a plain Markdown file on your local drive. You can open them in any text editor, back them up with any file-sync tool, and migrate to another app without any conversion step. Joplin uses a similar philosophy, storing notes locally by default and offering end-to-end encryption.
At the other end, Apple Notes scores a 3/10 on the Atlas Data Sovereignty Quotient. There is no native bulk export to a standard format. If you want to leave, you are looking at manual copy-paste or third-party tools that may not preserve formatting. Notion scores 5/10 — its export produces Markdown, but databases, linked pages, and embedded content often lose structure.
Local-First vs. Cloud-First: A Cost Comparison
The pricing models of local-first and cloud-first apps reflect a fundamental difference in how they treat your data. Cloud-first apps (Notion, Evernote, OneNote, Apple Notes) require a subscription to store your notes on their servers. Local-first apps (Obsidian, Joplin) store your notes on your device and charge only for optional sync services.
| App | Architecture | Mandatory Sync Cost | Optional Sync Cost |
|---|---|---|---|
| Obsidian | Local-first | $0 (local files only) | $4/month (Obsidian Sync) |
| Joplin | Local-first | $0 (local files only) | €2.99/month (Joplin Cloud) |
| Notion | Cloud-first | $10/user/month (Plus) | N/A |
| Evernote | Cloud-first | $14.99/month (Starter) | N/A |
| OneNote | Cloud-first | $0 (5GB limit) | $1.99/month for 100GB |
| Apple Notes | Cloud-first | $0 (5GB limit) | $0.99/month for 50GB |
The distinction matters because a local-first app cannot hold your data hostage. If Obsidian or Joplin raised their sync prices tomorrow, you would lose cloud sync — but your notes would remain on your device, fully accessible. If Evernote or Notion raised their prices, you would lose access to your notes entirely unless you paid.
Privacy and Encryption: Who Really Owns Your Notes?
Data ownership is not just about export formats — it is also about who can read your notes. Encryption practices vary dramatically across these apps.
| App | Encryption at Rest | End-to-End Encryption | Local-Only Mode |
|---|---|---|---|
| Joplin | AES-256 (NIST FIPS 197) | Yes (master password derived keys) | Yes |
| Obsidian | Device-level (OS dependent) | No (sync add-on uses TLS) | Yes |
| Notion | AES-256 (server-side) | No | No (limited offline cache) |
| Evernote | AES-256 (server-side) | No | No |
| OneNote | AES-128 (server-side) | No | No (limited offline cache) |
| Apple Notes | AES-128 (server-side) | Yes (iCloud end-to-end) | No (requires iCloud) |
Joplin stands out here. As noted in the Atlas evaluation, it uses AES-256 encryption with end-to-end keys derived from a master password, following NIST FIPS 197 standards. This means even Joplin's servers cannot read your notes. OneNote, by contrast, lacks true local-only encryption — your notes are encrypted at rest on Microsoft's servers, but Microsoft holds the keys.
Real Total Cost of Ownership Over 3 Years
This is the central calculation. We estimate the three-year cost for a single user who starts with the free plan and eventually needs to sync across devices. We also include a one-time migration cost estimate for users who later decide to leave.
| App | Year 1 Cost | Year 2 Cost | Year 3 Cost | Migration Cost (Est.) | 3-Year TCO |
|---|---|---|---|---|---|
| Obsidian (local + Sync) | $48 ($0 app + $48 Sync) | $48 | $48 | $0 (files are portable) | $144 |
| Joplin (local + Cloud) | $36 (€35.88 at €2.99/mo) | $36 | $36 | $0 (open format) | $108 |
| Notion (Plus plan) | $120 ($10/mo) | $120 | $120 | $50–$150 (manual cleanup) | $390–$510 |
| Evernote (Starter plan) | $180 ($14.99/mo) | $180 | $180 | $100–$200 (format loss) | $640–$740 |
| OneNote (100GB plan) | $24 ($1.99/mo) | $24 | $24 | $50–$100 (per-notebook export) | $122–$172 |
| Apple Notes (50GB plan) | $12 ($0.99/mo) | $12 | $12 | $200–$400 (no bulk export) | $224–$424 |
The results are striking. Obsidian and Joplin cost less over three years than any cloud-first app, even when you pay for their optional sync services. The difference is not just in subscription fees — it is in the migration cost. Apple Notes, despite having the lowest monthly price, carries a massive hidden cost if you ever need to leave, because there is no efficient bulk export path.
Verdict: When Is Free Worth It and When Does Paid Save You Money?
The answer depends on your time horizon and your tolerance for risk.
- If you are a casual user who takes fewer than 50 notes per year and does not need cross-device sync: free tiers from OneNote, Apple Notes, or Google Keep are genuinely costless. You have little to lose if you switch later.
- If you are a student or knowledge worker building a long-term knowledge base: start with Obsidian or Joplin. The $4/month or €2.99/month for sync is cheaper than any cloud-first subscription, and your notes will outlive any single app.
- If you are already locked into Evernote or Notion with a large archive: the cheapest option may be to stay, but you should immediately export a full backup in an open format. If you decide to migrate, budget for the time cost and expect some data loss.
- If privacy is your primary concern: Joplin is the only app in this comparison that offers user-controlled end-to-end encryption with local-first storage. Obsidian is a close second if you pair it with an encrypted sync method.
The note-taking app market is projected to reach $28.05 billion by 2030, according to The Business Research Company. As the market grows, the pressure on free tiers will only increase. The apps that survive and thrive will be the ones that respect your data sovereignty — not the ones that trap you.
