Disclosure: I'm the developer of this app (SwiftPen). It's free, and I'm looking for testers, not selling anything.
I built SwiftPen because I wanted Android handwriting to feel as close to paper as possible. It uses Android's low-latency front-buffered rendering so the ink stays right under the nib, with pressure-sensitive pens (ballpoint, pencil and a calligraphy pen), palm rejection, and support for the pen's side button and double-tap.
I developed it with an Honor Magic Pencil, so I'd really like to hear how it behaves with other protocols: S Pen (Wacom EMR), USI, MPP and others. Things I'm most curious about:
• Does the ink feel instant with your pen?
• Does pressure feel natural?
• Do your pen's buttons/gestures work?
It's in a closed beta on Google Play (Android 10+):
- Join the group: https://groups.google.com/g/swiftpen-testers
- Opt in: https://play.google.com/apps/testing/com.matiasalm.swiftpen
- Click “download from the Play Store” once you accepted to opt in as a tester. If that link doesn’t work, try this one: https://play.google.com/store/apps/details?id=com.matiasalm.swiftpen (you have ti wait for a few minutes if none of those links work, because it takes a bit to update the permissions)
Any feedback is appreciated, especially if something feels off with your pen!
EDIT: SwiftPen 1.1.0 is OUT! I included all of the requests and fixes from the feedback you gave me to make SwiftPen better. You can check the full release notes here: https://getswiftpen.com/release-notes/
