Many Tesla owners discover TeslaMate when they want to log and analyze their own driving data. But once you actually deploy it, you quickly realize how much weight comes with running Docker containers, backing up PostgreSQL, and maintaining Grafana dashboards. Add a Raspberry Pi or a VPS at $5–$20 per month, and the cost of running it forever isn't trivial either.
"I just want something simpler — ideally something that runs entirely on my iPhone." If that's you, this article compares three iOS alternatives to TeslaMate head-to-head, then identifies the best fit depending on your situation.

What is TeslaMate, and why look for alternatives?
TeslaMate is an open-source, self-hosted Tesla data logger written in Elixir and licensed under AGPLv3. It runs PostgreSQL, Grafana, and an MQTT broker via Docker, and Tesla owners host the entire stack themselves to capture high-fidelity driving records.
Powerful, yes — but here are the pain points users consistently mention:
- Setup is heavy: Docker + PostgreSQL + Grafana + MQTT. You also need basic networking knowledge.
- Recurring operating cost: A VPS or Raspberry Pi has to run 24/7. Electricity, hosting, or both add up monthly.
- You own all the failures: PostgreSQL backups, Grafana auth, TLS certificate renewal — every issue is yours to fix.
- Tesla auth tokens stored on your server: They're nearly as sensitive as a password, and they sit on a box you maintain.
- It's not iOS-native: Grafana isn't optimized for mobile, so glancing at it from inside the car is awkward.
For anyone who would rather spend that "ops time" actually driving their Tesla, an alternative becomes very attractive.
Alternative 1: HedgieMate (TeslaMate-connected)
HedgieMate is a native iOS app that visualizes data from a TeslaMate server. It supports iOS, macOS, watchOS, iPadOS, and Vision Pro, and you can check battery state-of-charge from your Apple Watch while driving.
- Price: Pro Lifetime $9.99 (one-time). Free tier shows up to 14 days of history.
- Connection: Requires a separate TeslaMate server — it's not a replacement, it's a "TeslaMate frontend".
- Languages: English, Korean, Chinese, German, and others. No Japanese.
HedgieMate makes sense if "I want to keep TeslaMate but replace Grafana with a polished iOS UI". The TeslaMate operational burden remains exactly the same.
Alternative 2: Mytess (TeslaMate-connected)
Mytess is another iOS app that connects to a TeslaMate server. It leans into modern iOS conveniences: real-time vehicle status, charging cost calculations, Dynamic Island support, and so on.
- Price: PRO version $9.99 one-time, with a 5-day refund policy.
- Connection: Requires both TeslaMate and the teslamateapi service running on your server.
- Languages: 13 languages supported, including Japanese.
- OS support: iOS 18.0 and above.
Mytess is polished and multilingual, but you still need to run TeslaMate plus the unofficial teslamateapi companion service yourself. The setup bar is actually higher than HedgieMate.
Alternative 3: VoltKeep (Direct Tesla connection)
VoltKeep takes a fundamentally different approach. Instead of going through a TeslaMate server, it connects directly to Tesla's official Fleet Telemetry API.
- Price: Free plan available; Pro is $2.99/month or $29.99/year (about 2 months free).
- Connection: No server required. Install the app, sign in via Tesla's official OAuth, and you're done.
- Languages: Japanese UI today; English UI in active development. App Store distribution is global, so you can install it from any country today.
- OS support: iOS 17.0 and above (iPhone).
- AI analysis: AI driving score, monthly AI report, battery degradation forecasting, automatic phantom drain detection.
- Privacy: Driving data is encrypted with X25519 public-key cryptography on the server; only your device can decrypt it. VINs are SHA-256 hashed.
VoltKeep's design philosophy: Get the same "see and analyze your driving in detail" experience as TeslaMate, without ever standing up a server.

|---|---|---|---|---|
| Connection method | Self-hosted server | Via TeslaMate | Via TeslaMate + API | Tesla Fleet API direct |
| Server setup | Required (Docker) | Required (TeslaMate) | Required (TeslaMate + API) | Not required |
| Upfront cost | Raspberry Pi or VPS | $9.99 + server | $9.99 + server | Free |
| Monthly cost | VPS ($5–$20) | VPS | VPS | $0 or $2.99 |
| Multi-language UI | Partial | No Japanese | 13 languages | JP today (EN coming) |
| Platform | Web (Grafana) | iOS / Mac / Watch | iOS 18+ | iOS 17+ |
| AI analysis | None | None | None | Yes (Pro) |
| Phantom drain detection | Manual visualization | Timeline view | Parking history | Auto-detect + push |
| Battery degradation forecast | None | Health view | Health view | Predictive model (Pro) |
| Encryption | You manage it | You manage it | You manage it | X25519 + VIN hashing |
So, which one should you pick?
Already running TeslaMate, just unhappy with Grafana → HedgieMate / Mytess
If you're willing to keep maintaining Docker and only want a nicer iOS frontend, these work. Pick HedgieMate for Apple Watch support, Mytess for the wider language coverage.
Want to escape server ops entirely → VoltKeep
If you want to drop Docker, PostgreSQL, and Grafana, stop paying for a VPS, and have everything run on your iPhone — VoltKeep is the right call. It connects directly to Tesla's official Fleet Telemetry API, so there's no intermediate server to operate or secure.
You value privacy and modern iOS UX → VoltKeep
VoltKeep is built iOS-first with end-to-end encryption (X25519 public-key crypto, VIN hashing) and built-in AI analysis. No hosting required, no Docker required. The UI is currently Japanese-only with an English version in development; the App Store listing is available worldwide.
TeslaMate-grade analysis. No server required.
Free plan covers driving routes, efficiency, and phantom drain detection.
Pro adds AI driving scores and battery degradation forecasting.
Frequently Asked Questions
Can I import my TeslaMate history into VoltKeep?
Not at the moment — there's no TeslaMate import feature today. VoltKeep starts collecting fresh driving data from the moment you connect.
Is connecting directly to Tesla's Fleet API safe?
Yes. Authentication uses Tesla's official OAuth flow, so your password is never shared. The Fleet Telemetry API is Tesla's official data delivery infrastructure — it's the same source TeslaMate uses locally.
What can I do on the free plan?
Map view of driving routes, efficiency tracking, automatic trip detection, monthly trends, phantom drain detection, widgets, and push notifications — all free. Only the AI analysis features are Pro-only.
