## What is Photo Editor?

Compare your photos side by side: Move the slider to easily grasp the differences. 

Is the lighting ok? Are the eyes open? Are all people smiling? And so on…

You often take several shots of the same scene, and then struggle to pick the best one. No more going back and forth - with TwoSlideOver, you just slide one photo on top of the other and see immediately which one to keep.

Use the powerful built-in photo editor to apply awesome filters, effects, and edits to your photo. While editing, compare to the original photo side by side.

Filters set a mood for the photo, such as "Rainy", or "Summer". The editing tools enable you to greatly enhance or change your photo. Effects can make your photo look strange, crazy or just funny. 

Stay tuned for even more possibilities in future updates.

Share your pick with friends or save it to the camera roll - or export the dual image.

We don’t gather, process or share any of your personal information, including your photos. If you choose to help us improve the app, you can enable sharing some anonymous usage statistics about OS version, device type, and what features are used most. Everything else stays on your device and we will keep it that way.

To transmit the usage statistics we use the service TelemetryDeck.

### 4/5 — Wichtige Möglichkeit fehlt…

*2025-03-22*

Fast perfekte App, aber es fehlt was sehr wichtiges: das anpassen der Bildposition. Sonst machen richtige Vergleiche mit Schieberegler nicht viel Sinn. Wenn man zB so wie ich die Entwicklung der Hautkrankheit verfolgen möchte, muss es unbedingt möglich sein beide Bilder so anzupassen, dass es wie ein nahtloses Bild erscheint. Wenn diese Funktion hinzugefügt wird, gibts die vollen 5 Sterne :)

### 5/5 — Super Foto-Editor

*2022-03-21*

Der Foto-Editor macht echt Spaß. Hoffentlich kommen noch mehr Effekte.

### 5/5 — Very nice, respects user privacy

*2022-01-21*

I'm very happy with this app. It's fast, does what it says it will do, and respects my privacy. The app starts with anonymous data collection turned off by default.

### 5/5 — Praktisch zum Bilder vergleichen

*2021-07-24*

Ich nutze die App öfter, um zwei sehr ähnliche Bilder zu vergleichen. Sehr praktisch, auch, weil man das „bessere“ Bild gleich teilen kann. Hoffe, es kommen bald noch mehr Effekte.

### 5/5 — Coole App

*2021-02-10*

Macht Spaß, Bilder zu vergleichen oder sie zu verfremden und dann abzuspeichern.

### 5/5 — Useful Creative Tool and Utility

*2021-02-09*

Good for comparing photos or images. Helps when choosing a shot or looking for differences between images. But also has some editing tools that creative people can use to make interesting art.

**Developer response:** I’m glad you like the app and thank you for your kind words!
